Overhead insulated cable is a kind of conductor with extruded insulation layer on the basis of single-layer or multi-layer aluminum strand stranding, which is mainly used for urban power distribution. The design of this cable is to solve the problem of complex short-circuit grounding and lightning strike lines in the urban power distribution environment, and improve the reliability of power supply by wrapping the insulation layer on the outer layer of the wire. Overhead insulated cables have various voltages and models. For example, models such as JKLYJ10KVA50 * 100 specify the voltage, model, material, cross-sectional area and length of the core.

Aluminum alloy cable is a new type of material power cable, with AA8000 series aluminum alloy as conductor material, with high conductivity, high temperature resistance and excellent mechanical properties.
The conductivity of aluminum alloy cable reaches 61.8 of copper, and the current carrying capacity is 79% of copper. While ensuring the stable performance of the cable, its weight is only half of that of copper cable, which helps to reduce the weight of the cable, reduce the installation cost, and reduce the wear of equipment and cables, making the installation work easier. In addition, the corrosion resistance, creep resistance and bending performance of aluminum alloy cables have been significantly improved, and they can maintain continuous and stable performance under long-term overload and overheating.

Introduction of Low Smoke Halogen Free Cable
Low smoke halogen-free cable is a high-performance energy-saving and environmentally friendly products, characterized by wire conductors do not contain halogen, sulfur, nitrogen and other halides. This kind of cable has flame retardant properties and excellent insulation properties, and at the same time has good electrical conductivity. Low smoke halogen-free cable is mainly used in the field of building electrical, communications, etc., can work normally under various harsh conditions. Its insulation and sheath insulation is good, the insulation resistance is large, and the resistivity is between 0.5 and 35, which meets the combustion performance requirements of wires and cables specified in QC/T 1847-1999. Low smoke halogen-free cable is the use of special low smoke flame retardant material production of wire, because of its own characteristics, can meet the flame retardant requirements, high safety. Although there is a standard support and supervision system, there are still many questions about the flame retardant material itself.
