Standard
　This product is produced according to GB/T12527 "Overhead insulated cables with rated voltage of 1kV and below" and GB/T14049 "Overhead insulated cables with rated voltage of 10kV".
Features and uses
　The product is weather-resistant cross-linked polyethylene, weather-resistant high-density polyethylene or weather-resistant PVC extruded outside of compacted copper and aluminum conductors. Its structure is simple, safe and reliable. At the same time, it has excellent mechanical and physical properties and electrical properties. Resistance to electrical tracking, creeping discharge resistance, and excellent atmospheric resistance. Compared with bare wires, the laying gap is small, the line corridor is saved, and the line voltage drop is reduced. Especially to reduce power supply accidents and ensure personal safety, it is suitable for cities, rural areas, mountainous areas, forest areas, and mining areas. It is an all-weather cable product.
