N2xoh Cable Single Core 600/1000V XLPE Insulated LSZH Sheathed Power Cables to IEC 60502-1 N2xh N2xh-J N2xh-O Cable

Insulation Material: The N2xoh series single-core cables use cross-linked polyethylene (XLPE) as the insulation material. XLPE is a polyethylene material treated by cross-linking. Compared with ordinary polyethylene, it has higher mechanical strength, temperature resistance and insulation performance. The cross-linking treatment makes the polyethylene molecules form a three-dimensional network structure, which greatly improves the heat resistance of the material, enabling it to maintain stable performance at higher temperatures and not easy to soften or melt. At the same time, XLPE has excellent electrical insulation performance, which can effectively block current leakage and ensure the efficiency and safety of power transmission. In addition, it also has good chemical corrosion resistance and aging resistance, and can be used for a long time in various harsh environments without performance degradation.

Sheath Material: The sheath of the cable is made of low-smoke zero-halogen (LSZH) material. LSZH material does not release a lot of smoke and toxic halogen gases when burned, which is its most significant advantage compared with traditional sheath materials. Traditional polyvinyl chloride (PVC) sheath materials will produce a lot of black smoke and toxic gases such as hydrogen chloride when burned, which will not only hinder the evacuation and rescue work of personnel but also cause serious harm to the human body. However, LSZH material has low smoke density and high light transmittance, which is conducive to maintaining a clear line of sight in case of fire. At the same time, it does not release toxic gases, which greatly improves the safety in case of fire. In addition, LSZH material also has certain mechanical strength and wear resistance, which can protect the internal insulation layer and conductor of the cable from external mechanical damage.

Conductor Material: The conductors of this series of cables usually use high-purity copper or aluminum as materials. Copper Conductors have excellent electrical conductivity, high conductivity and low resistance, which can reduce energy loss during power transmission and are suitable for scenarios with high requirements for electrical conductivity. Compared with Copper Conductors, Aluminum Conductors are lighter in weight and lower in cost, and have certain advantages in some occasions sensitive to weight and cost. Both copper and Aluminum Conductors undergo strict processing to ensure their surfaces are smooth and free of burrs, so as to ensure good electrical conductivity and bonding effect with the insulation layer.

Style Design: The N2xoh series single-core cables adopt a single-core design with a simple and compact structure. Compared with Multi-Core cables, single-core cables have the advantages of good bending performance and convenient laying, especially in some narrow spaces or occasions that require frequent bending. The appearance of the cable is usually dark colors such as black or gray, which is not only conducive to absorbing heat and reducing the impact of direct sunlight on the cable performance but also can blend with the surrounding environment to maintain beauty. In addition, the surface of the cable is usually printed with relevant specifications, models, standards and other information, which is convenient for users to identify and use.

Conductor Manufacturing: First, the copper or aluminum raw materials are smelted and rolled into round Copper Wires or round Aluminum Wires that meet the requirements. Then, multiple single wires are twisted together by bunch stranding or compact stranding to form a conductor with the required cross-section. During the stranding process, the structure of the conductor must be tight and round to improve its electrical conductivity and mechanical strength. At the same time, the surface of the conductor is treated to remove oil, oxide layers and other impurities on the surface to ensure a good bond between the conductor and the insulation layer.

Insulation Extrusion: Advanced extrusion equipment is used to evenly extrude XLPE material onto the outside of the conductor to form an insulation layer. During the extrusion process, parameters such as extrusion temperature, speed and pressure must be strictly controlled to ensure that the insulation layer has a uniform thickness, a smooth surface and no defects such as bubbles and impurities. After extrusion, the insulation layer is cross-linked, usually by warm water cross-linking or steam cross-linking, so that the XLPE material forms a stable three-dimensional network structure to obtain excellent performance.

Sheath Extrusion: LSZH sheath material is extruded onto the outside of the insulation layer. The process requirements for sheath extrusion are similar to those for insulation extrusion. It is necessary to ensure that the sheath has a uniform thickness, tightly wraps the outside of the insulation layer, and has good adhesion with the insulation layer. At the same time, various parameters during the extrusion process must be controlled to avoid quality problems such as sheath cracking and bubbles.

Inspection and Testing: Strict inspection and testing are carried out in all links of the production process. After the conductor is manufactured, parameters such as the diameter and resistance of the conductor are tested; after the insulation layer and sheath are extruded, their thickness, appearance, mechanical properties, electrical properties, etc. are inspected. In addition, the finished cable also needs to undergo overall performance tests, such as withstand voltage test, insulation resistance test, combustion performance test, etc., to ensure that the cable meets the requirements of the IEC 60502-1 standard. Only products that pass all inspection and testing can leave the factory for sale.

Packaging Materials: Wooden reels or cable spools are usually used as the main packaging carriers. Wooden reels or cable spools have sufficient strength and stability to bear the weight of the cable and the external forces during transportation. The material of the cable spool is generally high-quality wood or metal, which has undergone anti-corrosion treatment to prevent rot or rust during storage. At the same time, the cable is tightly wrapped on the reel with plastic film or linen to prevent the cable from being affected by dust, moisture and direct sunlight.

Packaging Specifications: Different packaging specifications are adopted according to the length and cross-sectional size of the cable. Generally speaking, the length of each reel of cable can be customized according to user needs, and common lengths are 100 meters, 200 meters, 500 meters, etc. For cables with larger cross-sections, the length of each reel is relatively short to facilitate transportation and handling; for cables with smaller cross-sections, the length of each reel can be longer to improve transportation efficiency. The packaging will clearly indicate the model, specification, length, weight, manufacturer and other information of the cable, which is convenient for users to identify and accept.

Packaging Marks: In addition to the above basic information, some warning marks such as "Handle with Care", "Do Not Invert", "Moisture-proof and Sun-proof" are also marked on the packaging to remind transportation and storage personnel to handle the cable correctly. At the same time, product quality inspection certificates and user manuals and other documents are also attached to facilitate users to understand the relevant information and usage methods of the product.

Transportation Methods: The N2xoh series single-core cables can be transported by various means such as road transportation, railway transportation, and waterway transportation. For short-distance transportation, road transportation is usually used, which is flexible and convenient and can directly deliver the cables to the user's designated location. For long-distance transportation, railway transportation and waterway transportation have the advantages of large transportation volume and low cost. When choosing the transportation method, comprehensive consideration is given to factors such as the quantity of cables, destination, and transportation time to ensure that the cables can be delivered safely and timely.

Transportation Requirements: During transportation, it is necessary to ensure that the packaging of the cable is intact to avoid mechanical damage to the cable caused by extrusion, collision, dragging, etc. The cable reel should be placed horizontally and must not be inverted or tilted to prevent the cable from falling off the reel. At the same time, the cable should be avoided from contact with sharp objects and corrosive substances to prevent damage to the sheath and insulation layer of the cable. During transportation, attention should also be paid to sun protection, moisture-proof and rain-proof to avoid the cable being affected by extreme environmental conditions. Transport vehicles or ships should have good ventilation conditions to prevent performance changes of the cable due to high temperature during transportation.

Transportation Responsibility: During the transportation of the cable, the transporter shall bear corresponding responsibilities.
