I. Information Related to the Product Itself
(I) Specification Parameters
The E-Yy, E-Y2y, E-Ayy, E-Ay2y, and E-A2y series
Power Cables have clear and standardized settings in terms of specification parameters to meet power transmission needs in different scenarios.
The conductors of this series of cables are aluminum cores, and their cross-sectional areas cover a variety of common specifications, which can adapt to different current load conditions. From the daily electricity use of small buildings to the power supply of small industrial equipment, you can find the corresponding suitable conductor specifications. After testing, under standard working conditions, the continuous current-carrying capacity of cables of different specifications is stable, which can meet the basic requirements of small and medium-power power transmission.
The thickness of the insulation layer strictly follows relevant standards. The thickness of the polyvinyl chloride (PVC) insulation layer is designed according to the rated voltage and use scenario of the cable. Sufficient insulation thickness ensures that the cable has good insulation performance, high insulation resistance, can effectively isolate current, reduce the risk of electric leakage, and ensure the safety of power transmission.
The high-density polyethylene (HDPE) outer sheath also has a clear thickness standard, and its thickness can provide effective protection for the cable, resisting erosion from the external environment and mechanical impact. The overall outer diameter of the cable has been optimized. On the premise of ensuring various performances, it is convenient to operate in various laying environments, such as passing through wall holes and pipes.
In addition, the bending radius of this series of cables also meets relevant regulations. The good
Flexibility enables the cable to adapt to a certain bending angle during laying, reducing construction difficulty.
(II) Characteristic Uses
Based on its unique performance combination, this series of cables have a wide range of targeted characteristic uses.
In the field of building power distribution, it is an ideal choice for civil buildings and small commercial buildings. In civil buildings, it can be used for power distribution lines in residential buildings to transmit power from the distribution box to electrical equipment such as sockets and lamps in various rooms. The lightweight characteristic of its aluminum core reduces the difficulty of laying in building walls and ceilings. The PVC insulation layer and HDPE outer sheath can adapt to the relatively dry environment inside the building while ensuring electricity safety. In small commercial buildings such as convenience stores and small office buildings, this series of cables can meet the power supply needs of lighting, air conditioners, office equipment, etc., and their stable performance ensures the normal operation of commercial activities.
This series of cables perform well in outdoor temporary power supply scenarios. For example, in outdoor construction sites and large outdoor activity venues, temporary power supply lines need to be built. The HDPE outer sheath of the cable is UV-resistant and resistant to wind and rain erosion, and can maintain stable performance under complex outdoor weather conditions. Its flexibility is convenient for transportation and temporary laying, and can quickly provide power support for construction equipment and activity lighting, and is not easy to be damaged due to the influence of the external environment during use.
Wiring of small industrial equipment is also an important application scenario. For some small industrial equipment with relatively low power, such as small machine tools and auxiliary equipment of production lines, the requirements for
Power Supply Cables focus on stability and economy. This series of cables can meet the power transmission needs of these equipment. The cost advantage of aluminum cores reduces the equipment investment cost of enterprises. At the same time, the performance of insulation and sheath materials ensures the safe operation of the equipment and reduces equipment failures caused by cable problems.
In addition, in the agricultural field, such as power supply for small greenhouses, this series of cables can also play a role. There may be a certain humidity in greenhouses, and the moisture resistance of the HDPE outer sheath can ensure the normal operation of the cable, providing power for lighting and irrigation equipment in the greenhouse.
(III) Material and Style
Conductor Material: The conductors of this series of cables are made of high-quality aluminum materials. Aluminum has good electrical conductivity. Although its conductivity is slightly lower than that of copper, it can fully meet the needs in small and medium-power power transmission scenarios. Moreover, the density of aluminum is small, making the overall weight of the cable relatively light. This advantage is particularly obvious during laying, which can reduce labor and equipment costs during construction. At the same time, the Aluminum Conductor has undergone special surface treatment to improve its oxidation resistance and extend the service life of the cable.
Insulation and Sheath Materials: The insulation layer is made of polyvinyl chloride (PVC) material. PVC has excellent insulation performance, which can effectively prevent current leakage and ensure the safety of power transmission. It also has certain temperature resistance and can work stably in an ambient temperature of -15℃ to 60℃, adapting to most common environments. In addition, the cost of PVC material is relatively low, which helps to control the overall cost of the cable.
The outer sheath is made of high-density polyethylene (HDPE) material. HDPE has excellent weather resistance, can resist UV radiation, and is not easy to age due to long-term exposure to the outdoors. It has strong acid and alkali corrosion resistance and can adapt to erosion from environments such as humid soil and slightly corrosive liquids. At the same time, the HDPE outer sheath has high mechanical strength and good impact resistance, which can reduce damage to the cable caused by collision and extrusion during transportation, laying and use.
Style Design: The cable adopts an overall circular structure design. This style is not only beautiful, but more importantly, it can make the cable evenly distribute pressure when stressed, improving its compressive performance. The circular structure is also convenient for winding, storage and transportation of the cable, reducing storage space. The surface of the cable is smooth, so it is not easy to generate excessive friction with other objects during laying, reducing the risk of damage. In addition, this series of cables has good flexibility and can be properly bent according to laying needs, adapting to different installation paths, such as corner turns and passing through narrow spaces.
(IV) Production Process
The production process of this series of cables is strict and standardized to ensure that product quality meets relevant standards.
In the conductor manufacturing link, high-purity aluminum ingots are first selected and made into aluminum rods through smelting, casting and other processes. Then, the aluminum rod is drawn into
Aluminum Wires of the required diameter by a wire drawing machine. During the wire drawing process, the wire drawing speed and temperature are accurately controlled to ensure the dimensional accuracy and mechanical properties of the
Aluminum Wires. After that, multiple aluminum wires are stranded to form a conductor according to the cable specifications. The stranding process can improve the flexibility and overall strength of the conductor, making the conductor not easy to break when bent.
Insulation layer extrusion is one of the key processes. The PVC material is heated to a molten state and evenly extruded and wrapped on the surface of the conductor through an extruder to form an insulation layer. During the extrusion process, the extrusion temperature, pressure and speed are strictly controlled to ensure that the insulation layer has uniform thickness, a smooth surface, is closely combined with the conductor, and has no defects such as bubbles and impurities. The quality of the insulation layer directly affects the insulation performance of the cable, so real-time monitoring and quality inspection are carried out in this link.
The outer sheath extrusion process is similar to that of the insulation layer. The HDPE material is heated and melted, then extruded and wrapped outside the insulation layer through an extruder to form an outer sheath. During the extrusion process, it is necessary to ensure that the outer sheath is closely attached to the insulation layer with uniform thickness to play a good protective role. At the same time, process parameters need to be controlled to avoid problems such as sheath cracking and wrinkling.
After production, the cable needs to undergo a series of strict tests, including insulation resistance test, voltage withstand test, mechanical performance test, etc. Only products that pass all tests can enter the subsequent packaging link to ensure that the cables leaving the factory are of reliable quality.
II. General Product Information
(I) Packaging
To ensure the integrity of the cable during transportation and storage, the packaging design of this series of cables is scientific and reasonable.
Cables are usually wrapped and packaged with wooden or plastic reels. The wooden reels are made of hard and non-deformable wood and undergo drying treatment to prevent mildew and deformation due to moisture during storage and transportation. The plastic reels have the characteristics of light weight and corrosion resistance, and are suitable for short-distance transportation and storage in humid environments.
The length of each reel of cable varies according to the model and specification, usually 100 meters, 200 meters and other common lengths, which is convenient for users to cut according to actual needs. When winding the cable, ensure that the cable is arranged neatly and tightly to avoid mutual winding and extrusion, and reduce wear on the cable surface.
The outside of the package will be wrapped with a layer of plastic film to play a role in moisture-proof and dust-proof, protecting the cable from external environmental pollution. At the same time, the product model, specification, length, manufacturer, production date, implementation standard and other information are clearly marked on the package to facilitate user identification and acceptance. For export products, corresponding English logos and certification marks will also be marked.
(II) Transportation
There are clear specifications and requirements for the cable transportation link to ensure that the product is not damaged during transportation.
The transportation method is selected according to the transportation distance and quantity. For short-distance transportation, truck transportation is generally used. The compartment of the transport vehicle should be kept clean and dry to avoid contact between the cable and sharp objects and corrosive substances. During transportation, the cable reel must be fixed firmly to prevent rolling and collision during vehicle operation. Ropes, brackets and other fixing devices can be used.
For long-distance transportation, railway transportation or logistics 专线 transportation can be chosen. Railway transportation has good stability and is suitable for long-distance transportation of large quantities of cables, which can reduce the impact of bumps during transportation on the cables. Logistics 专线 transportation can provide door-to-door service, and there are special personnel responsible for the transportation process, who can deal with problems in transportation in a timely manner.
During transportation, the cable should be avoided from direct sunlight, rain and extreme temperatures. In high temperature in summer, sunshade treatment can be carried out on the cable; in low temperature in winter, it is necessary to prevent the cable from becoming brittle and damaged due to low temperature. When loading and unloading cables, special hoisting equipment must be used, and rough loading and unloading are strictly prohibited to avoid damage to the cable reel and the cable itself.
