Rated Voltage: The rated voltage of this cable is 600/1000V, and this parameter range is carefully designed to meet the needs of various power distribution systems. Among them, 600V is suitable for low-voltage power distribution scenarios, such as branch circuits in large commercial buildings and local power supply for some industrial equipment; 1000V is suitable for medium-voltage environments, and can be used for main power distribution lines in industrial parks and some branch lines of urban power grids. In actual operation, the working voltage of the cable will not exceed the upper limit of its rated voltage to ensure the stability and safety of power transmission and avoid problems such as insulation layer breakdown caused by excessive voltage.

Conductor Specification: The cross-sectional area of the conductor is 60mm², and this specification is determined according to the power demand of high-power equipment. The conductor is made of high-purity stranded copper with a purity of over 99.95%. The high-purity copper ensures excellent conductivity, with a conductivity of more than 100% IACS (International Annealed Copper Standard), which can effectively reduce energy loss during current transmission. In terms of current-carrying capacity, when the cable is laid in air, the current-carrying capacity can reach 200-230A, and the specific value will be affected by environmental temperature, laying method and other factors. For example, when the ambient temperature rises to 40℃, the current-carrying capacity will be reduced by about 15% compared with that at 25℃; when laid through a pipe with a large number of cables in the pipe, the current-carrying capacity may be reduced by 20%-30%.

Conductor Structure: The conductor adopts a stranded structure, which is composed of multiple thin Copper Wires with a diameter of 0.63mm, usually 196 wires. The stranding pitch is strictly controlled between 25-30mm. The reasonable pitch design not only enhances the Flexibility of the conductor, facilitating operations such as bending and threading in complex wiring environments, but also reduces the loss caused by the current skin effect, and at the same time improves the tensile and vibration resistance of the conductor. Tests show that the tensile strength of the conductor is not less than 200MPa, which can withstand a certain degree of tension during construction and use.

Insulation Layer Parameters: The insulation layer is made of high-quality polyvinyl chloride (PVC) material with a thickness of about 1.8-2.0mm. The insulation resistance of the insulation layer is not less than 100MΩ, which can effectively prevent current leakage and ensure electrical safety. It has excellent chemical corrosion resistance and can resist the erosion of acid and alkali solutions with a concentration of no more than 10% and common oils. In terms of temperature resistance, the insulation layer can work stably in the ambient temperature range of -15℃ to 70℃. At -15℃, it can still maintain good flexibility without embrittlement; at 70℃, the mechanical properties and insulation performance of the insulation layer will not decrease significantly. In addition, the flame retardant grade of the insulation layer reaches UL94 V-0, which can self-extinguish quickly when exposed to open fire without dripping, meeting relevant fire safety standards.

Overall Size: The overall outer diameter of the cable is determined by the conductor diameter and the thickness of the insulation layer, which is about 12-13mm. This size design not only ensures the stability of the internal structure of the cable but also facilitates laying in narrow spaces such as pipes and cable trays, without increasing the construction difficulty due to excessive outer diameter.

Length Specification: Common cable lengths on the market include 100 meters, 200 meters, 300 meters, 500 meters, etc., in coiled packaging. They can also be customized according to the special needs of customers, with a maximum customization length of 1000 meters. The length error is controlled within ±0.5% to ensure that the actual length is basically consistent with the marked length, meeting the laying needs of different projects.

Weight Parameters: The weight of each meter of cable is about 0.65kg, and the weight of a 100-meter-long cable is about 65kg. This weight requires appropriate tools to assist in handling during transportation and installation to improve efficiency and safety.

Industrial Field: In industrial production, 60mm² Stranded Copper Cable 600/1000V PVC insulated is widely used. It can be used as the Power Cable of factory production lines to provide power for large industrial motors (such as asynchronous motors with power above 100kW), stamping equipment, injection molding machines, etc. These equipment have large power and long running time, and have high requirements for the current-carrying capacity and stability of the cable. This cable can meet the needs of their long-term stable operation. In high-temperature and dusty environments in metallurgy, chemical industry and other industries, the cable can also work normally because its insulation layer has good temperature resistance and chemical corrosion resistance. For example, in chemical production workshops, cables can be used to connect equipment such as stirring motors of reaction kettles to resist the erosion of possible chemical gases in the workshop.

Large Commercial Building Field: Large commercial buildings such as shopping malls, office buildings, hotels, etc., have many electrical equipment and large total power. This cable is suitable for power distribution trunks and Emergency Power Supply systems. The power distribution trunk distributes power from the main distribution room to the distribution rooms on each floor, and then from the distribution rooms to each area. The strong current-carrying capacity of this cable can meet the total power demand of the entire building. The emergency power supply system supplies power to important loads such as fire-fighting equipment and emergency lighting when the commercial power is interrupted. The reliability of this cable can ensure the timely switching and stable operation of the emergency power supply, ensuring personal safety and building safety.

Public Facilities Field: The main power distribution lines of public facilities such as gymnasiums, convention centers, and hospitals often use this cable. The total power of lighting systems, audio equipment, air conditioning systems, etc. in gymnasiums is relatively large, requiring reliable power transmission; convention centers rely on stable power supply for a large number of exhibition equipment and temporary lighting equipment when holding large-scale exhibitions; operating room equipment in hospitals and life support equipment in ICU wards have extremely high requirements for the continuity and stability of power. This cable can provide safe and reliable power guarantee for them, avoiding serious consequences caused by power interruption.

Outdoor Power Distribution Engineering Field: Due to its high rated voltage and current-carrying capacity, this cable is also often used in outdoor power distribution projects. In urban power grid transformation, it can be used as a branch cable to connect transformers and distribution cabinets, improving the power supply capacity of the power grid; in industrial parks, it is used to connect the power distribution systems of various factories to realize centralized distribution and efficient transmission of electricity. In outdoor environments, wind, sun, rain and other conditions may be encountered. The insulation layer of this cable has good weather resistance and can work stably in outdoor environments for a long time.

Conductor Material: The conductor is made of high-purity electrolytic copper. Electrolytic copper removes impurities through electrolytic refining process, with a purity of more than 99.95%. This kind of copper has extremely high conductivity, which can effectively reduce energy loss during current transmission. At the same time, electrolytic copper has good ductility and toughness, which is not easy to break during stranding, ensuring the stability of the conductor structure. In addition, the surface of electrolytic copper is smooth and not easy to oxidize, and can maintain good conductivity during long-term use.

Insulation Layer Material: The insulation layer is made of high-quality polyvinyl chloride (PVC) material, which is made of polyvinyl chloride resin added with plasticizers, stabilizers, flame retardants and other additives. PVC material has good insulation performance, which can effectively isolate current and ensure electrical safety. It has high mechanical strength, with a tensile strength of not less than 15MPa and an elongation at break of not less than 200%, which can withstand mechanical stress during construction and use. At the same time, PVC material has good processing performance, which is convenient for forming a uniform insulation layer through extrusion process.

Style Design: The cable is cylindrical in shape with a smooth and flat appearance. The color of the insulation layer is usually black or gray. These two colors not only conform to industry practices but also have good dirt resistance, so they are not easy to get dirty when used in outdoor and industrial environments. The cable is packaged in coils, and the reel is made of high-strength plastic. The inner diameter of the reel is 100-120mm, and the outer diameter depends on the length of the cable. For example, the outer diameter of the reel for a 100-meter-long cable is about 500mm. There are baffles at both ends of the reel to prevent the cable from loosening during storage and transportation.

Copper Smelting and Drawing: First, high-purity copper raw materials are put into a melting furnace for smelting. The smelting temperature is controlled at 1100-1200℃ to remove impurities in the copper, and copper water with a purity of more than 99.95% is obtained. The copper water is made into copper rods with a diameter of 8mm through continuous casting process. After cooling, the copper rods enter the wire drawing process. During the drawing process, the copper rod is gradually drawn through multiple wire drawing dies with different apertures, and finally made into fine copper wires with a diameter of 0.63mm. The drawing speed is controlled at 8-10m/s, and the mold is cooled by water at the same time to ensure that the diameter of the copper wire is uniform, the surface is smooth, and there are no scratches, cracks and other defects. The drawn copper wire is annealed at 400-450℃ for 2-3 hours to eliminate the internal stress generated during the drawing process and improve the flexibility and ductility of the copper wire.

Conductor Stranding: 196 fine copper wires with a diameter of 0.63mm are stranded at a pitch of 25-30mm by stranding equipment. The stranding equipment adopts a multi-head stranding machine, which can accurately control the tension of each copper wire to ensure that the Stranded Conductor has a compact and round structure, and the cross-sectional size meets the requirements of 60mm². During the stranding process, the diameter of the conductor is monitored in real-time, and the deviation is controlled within ±0.1mm. After stranding, the conductor is inspected for appearance to ensure that there are no loose strands, broken wires and other phenomena.

Insulation Layer Extrusion: The extrusion molding process is used to wrap the PVC Insulation layer on the outer layer of the stranded conductor. First, PVC particles are added into the hopper of the extruder and heated to melt, with the melting temperature controlled at 160-180℃. The molten PVC material is evenly coated on the surface of the conductor through the die of the extruder. The size of the die is determined according to the thickness of the insulation layer and the diameter of the conductor to ensure that the thickness of the insulation layer reaches 1.8-2.0mm. The extrusion speed is matched with the traction speed of the conductor, controlled at 5-8m/min to ensure that the insulation layer is uniform. The extruded cable is cooled in a cooling water tank to make the insulation layer solidify quickly.

Quality Inspection: Strict quality inspection procedures are set up in each link of the production process. After copper wire drawing, parameters such as diameter, tensile strength and elongation of the copper wire are tested; after conductor stranding, DC resistance, cross-sectional area and appearance of the conductor are tested; after insulation layer extrusion, thickness, insulation resistance, voltage resistance performance and flame retardant performance of the insulation layer are tested. The finished cable also needs to undergo bending test, wear test, aging test, etc. For example, in the withstand voltage test, the cable must not break down under 2500V voltage for 5 minutes; in the bending test, the cable is bent 180 degrees with a radius 6 times the outer diameter of the cable, and after 10 repetitions, the insulation layer has no cracks.

Packaging Materials: The cable uses high-strength plastic reels as the main packaging material. The plastic reels are made of polypropylene (PP), which has the characteristics of compression resistance, drop resistance and corrosion resistance, and can bear the weight of the cable and the impact force during transportation. The two ends of the reel are provided with metal flanges to enhance the strength of the reel. For coiled cables, first wrap a layer of moisture-proof paper, then wrap with plastic film. The moisture-proof paper can effectively prevent the cable from getting damp, and the plastic film plays the role of dust prevention and cable fixing. For cables with longer length and larger weight, a wooden frame is also 套在 the outside of the reel to further protect the cable from damage during transportation.

Packaging Method: The cable is neatly wound on the plastic reel, and each layer must be tightly arranged without crossing or twisting. After winding, wrap the outer layer of the cable with moisture-proof paper, and the overlapping width of the moisture-proof paper is not less than 50mm. Then wrap the plastic film from one end of the reel to the other end, keeping appropriate tension during winding to ensure that the plastic film is closely attached to the cable. On the obvious position of the package, labels are used to mark the product name, model, specification (60mm², 600/1000V), length, production date, batch number, execution standard, manufacturer name and contact information. For cables packaged with wooden frames, the frame and the reel are fixed with bolts to prevent the reel from shaking in the frame.

Packaging Marks: In addition to basic product information, the package also prints some warning marks, such as "Avoid Sun Exposure", "Avoid Rain", "Do Not Invert", "Stacking Limit", etc. The "Stacking Limit" mark indicates the maximum number of layers that the packaged cables can be stacked, usually no more than 2 layers. The marks are printed with sun-resistant and wear-resistant ink to ensure that they do not fade or blur during outdoor storage and long-distance transportation.

Transportation Methods: According to the customer's geographical location and order quantity, select the appropriate transportation method. For short-distance transportation (such as within a radius of 500 kilometers), road transportation is adopted, and van trucks with rainproof and sun-proof facilities are selected. The bottom of the truck's carriage is paved with moisture-proof wooden boards to prevent the cables from getting damp. For long-distance transportation, railway transportation or water transportation is adopted. Railway transportation uses container transportation, and the container is kept dry and clean; water transportation stores the cables in the cabin, away from water sources and corrosive substances, and takes good fixing measures to prevent the cables from shaking and colliding during navigation. For emergency orders, air transportation can be adopted. During air transportation, it is necessary to comply with the airline's regulations on the weight and size of goods and specially package the cables.

Transportation Precautions: During transportation, the cables should avoid severe collision, extrusion, exposure to the sun and rain. When loading, the cable reels should be placed horizontally, with the axis consistent with the driving direction of the vehicle, avoiding stacking too high. When stacking, wooden boards are placed between the upper and lower reels to prevent mutual extrusion. For cables packaged with wooden frames, the frames are fixed on the transport tool with steel wire ropes or fastening belts to ensure that they do not shift during transportation. During transportation, the cable should be avoided from contact with sharp objects to avoid damaging the insulation layer and packaging. At the same time, the temperature of the transportation environment should be controlled between -20℃ and 50℃, and the relative humidity should not exceed 85% to avoid extreme temperatures and humid environments affecting the performance of the cable.

Transportation Tracking: The company cooperates with professional logistics companies to provide customers with full transportation tracking services. Customers can query the transportation location, transportation status and estimated arrival time of the cable by entering the waybill number through the logistics query system on the company's official website or the customer service hotline of the logistics company. If abnormal situations such as traffic jams and bad weather are encountered during transportation, the logistics company will timely communicate with customers and the company, explain the situation and adjust the transportation plan to ensure that the cables can arrive on time.

Delivery Process: After receiving the customer's order, the sales department first conducts order review to confirm whether the product model, specification, quantity, delivery date, delivery address and other information are accurate. After passing the review, the order information is transmitted to the warehouse department. Warehouse personnel retrieve the corresponding cables from the inventory according to the order information, conduct quantity checking and appearance inspection to ensure that the cable packaging is intact, the logo is clear and there is no damage. After goods preparation is completed, warehouse personnel transport the cables to the delivery area and notify the logistics department to arrange transportation. The logistics department connects with the logistics company to determine the transport vehicle and transport route, and go through relevant transport procedures. Before delivery, the sales department notifies the customer of the delivery information (including logistics company name, waybill number, estimated arrival time, etc.) via SMS, email, etc., so that the customer can prepare for receipt.

Delivery Time: For products in stock, delivery is completed within 2-3 working days after order confirmation; for products that need customized lengths, production and delivery are completed within 7-10 working days according to the customized length and production plan.
