120mm 150mm 185mm Copper Power Cable 0.6/1kv Freetox Halogen-Free Duplex Triplex Unipolar Cable N2xoh

Conductor Material: The conductor of this series of cables is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity electrolytic copper has excellent conductivity and high conductivity, which can effectively reduce energy loss during current transmission and improve power transmission efficiency. At the same time, electrolytic copper has good ductility and Flexibility, which is convenient for stranding and other processing during cable production, and can also adapt to different bending angles during laying without breaking. In addition, electrolytic copper has good chemical stability and is not easy to be corroded, which can ensure that the cable maintains good conductivity during long-term use and prolong the service life of the cable.

Insulation Material: The insulation layer of the cable uses Freetox halogen-free material, which is an environmentally friendly insulation material. Compared with traditional halogen-containing insulation materials, Freetox halogen-free materials do not release toxic hydrogen halide gases such as hydrogen chloride when burned, which greatly reduces the harm to humans and the environment in case of fire. At the same time, it has good electrical insulation performance, which can effectively block current and ensure that the insulation resistance and voltage resistance performance of the cable meet the standard requirements. This material also has certain mechanical strength and aging resistance, and can resist external mechanical impact and environmental factors such as temperature changes and ultraviolet radiation, maintaining the stability and integrity of the insulation layer.

Style Design: This series of cables has various structural types such as duplex, triplex and unipolar. A duplex cable is composed of two Insulated Cores, wrapped with a sheath; a triplex cable contains three insulated cores, which are tightly wrapped by a sheath; a unipolar cable has only one insulated core. Different structural designs meet the needs of different circuits. The Multi-Core structure is convenient for transmitting multi-phase current at the same time, reducing the complexity of line laying.

Conductor Stranding: First, high-purity electrolytic copper rods are drawn into copper wires of the required diameter through a wire drawing machine. Then, according to different conductor cross-sectional areas, multiple copper wires are stranded in a certain way. During the stranding process, it is necessary to strictly control the stranding pitch and tension to ensure the roundness and tightness of the conductor, reduce the resistance of the conductor, and improve the conductivity. The Stranded Conductor needs to be surface-treated to remove oil and impurities on the surface to ensure good bonding with the insulation layer.

Insulation Extrusion: Freetox halogen-free insulation material is added to the extruder, heated and melted, and then evenly extruded and coated on the surface of the stranded conductor through a mold to form an insulation layer. During the extrusion process, parameters such as extrusion temperature, speed, and pressure must be precisely controlled. Excessively high temperature will cause the insulation material to decompose, affecting the insulation performance; excessively low temperature will cause defects such as bubbles and material shortage in the insulation layer. The stability of extrusion speed and pressure can ensure uniform thickness of the insulation layer, close bonding with the conductor, and no looseness.

Cabling (Multi-Core Cables): For duplex and triplex cables, it is necessary to cable multiple cores wrapped with insulation layers. During cabling, the cores are stranded together according to a certain stranding direction and pitch, and at the same time, some halogen-free filling materials are filled during the stranding process to make the structure of the cable more round and stable. The filling material is compatible with the insulation material and sheath material and will not have an adverse impact on the performance of the cable.

Sheath Extrusion: After cabling (for unipolar cables, after insulation layer extrusion), sheath extrusion is carried out. Freetox halogen-free sheath material is added to the extruder and extruded and coated on the cabled core or the unipolar insulated core to form a sheath layer. The sheath extrusion process is similar to insulation extrusion, and various parameters need to be strictly controlled to ensure uniform thickness and smooth surface of the sheath, close bonding with the internal structure, and effective protection of the internal core from external mechanical damage and environmental erosion.

Inspection and Testing: Strict inspection and testing are carried out in all links of the production process. The diameter, resistance, and stranding quality of the conductor need to be sampled and tested; the thickness, insulation resistance, voltage resistance performance, and mechanical performance of the insulation layer need to be comprehensively tested; the outer diameter, roundness, and stranding quality of the cabled cable need to be checked; the thickness, appearance, and weather resistance of the sheath layer also need to be inspected. The finished cable also needs to undergo overall performance tests, such as current-carrying capacity test, short-circuit test, and combustion performance test (to verify halogen-free characteristics), to ensure that all performance indicators meet relevant standards and design requirements. Only products that pass all inspections and tests can leave the factory for sale.

Packaging Materials: Cables are usually wound on steel cable reels. Steel cable reels have the characteristics of high strength and high load-bearing capacity, and can bear the weight of the cable and the external force during transportation and handling. The size of the cable reel is determined according to the specification and length of the cable. The length of each reel of 120mm², 150mm², and 185mm² cables is usually 100 meters, 200 meters, or 500 meters. On the cable reel, the cable is tightly wound and wrapped with plastic film, which can effectively prevent the cable from being affected by dust, moisture, and direct sunlight, keeping the cable clean and dry. For some small batches of short cables, wooden box packaging can also be used. Buffer materials such as foam are placed inside the wooden box to avoid damage caused by mutual collision during transportation.

Packaging Marks: Clear packaging marks are printed on the surface of the cable reel or wooden box. The marking content includes product name, model (N2xoh), specification (120mm², 150mm², 185mm²), length, rated voltage (0.6/1kV), structural type (duplex, triplex, unipolar), execution standard, manufacturer, production date, shelf life, etc., which is convenient for users to identify and check during receipt and acceptance. At the same time, some warning signs such as "Do Not Invert", "Handle with Care", "Moisture-proof and Sun-proof", "Keep Away from Fire" are also printed on the packaging to remind transportation and storage personnel to handle the cable correctly and avoid cable damage due to improper operation.

Packaging Requirements: During the packaging process, it is necessary to ensure that the cable is neatly wound on the cable reel without distortion or knotting. The two ends of the cable must be sealed to prevent moisture and impurities from entering the inside of the cable. For cables packaged in wooden boxes, the firmness of the wooden box must be ensured, and the buffer materials inside the box must be filled in place to ensure that the cable does not shake in the box. After packaging, the packaging must be inspected to ensure that the marks are clear and firm and the packaging is intact.

Transportation Methods: This series of cables can be transported by various means such as road transportation, railway transportation, and waterway transportation. Road transportation has the characteristics of high flexibility and can realize door-to-door service, suitable for short-distance transportation and small-batch transportation, and can quickly deliver cables to the destination. Railway transportation has large capacity and relatively low cost, suitable for medium and long-distance transportation and large-batch transportation, especially for cross-regional cargo transportation. Waterway transportation is suitable for long-distance and large-batch transportation, especially for coastal areas or cities with ports, with low transportation costs but relatively long transportation time. When choosing the transportation method, it is necessary to comprehensively consider factors such as the quantity of cables, transportation distance, time requirements, and cost budget, and select the most suitable transportation method.

Transportation Precautions: During transportation, it is necessary to ensure the stability of the cable reel or wooden box to avoid rolling and collision on the transport tool. The cable reel should be placed horizontally, and inversion or tilting is strictly prohibited to prevent the cable from falling off the cable reel or being damaged by extrusion. The compartments and cargo holds of transport vehicles or ships must be kept clean and dry, without sharp objects, corrosive substances, and flammable and explosive items, to avoid mechanical damage or chemical corrosion to the cable. During transportation, measures for moisture-proof, sun-proof, rain-proof, and high-temperature prevention must be taken, such as covering the cable tightly with a tarpaulin to avoid the cable being affected by bad weather. At the same time, traffic rules and transportation regulations must be observed, and transportation routes and time must be reasonably arranged to ensure transportation safety.

Transportation Responsibility: The transporter shall be responsible for the transportation process of the cable. Before transportation, the transporter shall inspect the packaging and quantity of the cable, and sign for receipt after confirmation. During transportation, the goods must be properly stored to ensure that the cable is delivered to the destination safely and intactly. If the cable is damaged, lost, or delayed due to the transporter's reasons, the transporter shall bear the corresponding compensation liability in accordance with the terms of the transportation contract. The shipper shall maintain close communication with the transporter, keep abreast of the transportation status of the goods, and negotiate solutions together in case of abnormal situations.
