Product Desciption
The so-called overhead line is relative to the cable said, is set up by the tower wire at a certain height of the transmission of electric power line. For the overhead lines of high voltage transmission and distribution network, the ground insulation is generally air dependent. The distribution lines (except 380V below 10kV) used bare wires in the past. However, due to the complex distribution environment in urban areas, short-circuit grounding and lightning strikes often occur, resulting in reduced reliability of power supply. Therefore, generally, overhead lines below 10kV are insulated wires (that is, wires are wrapped with insulating layers), which is called insulated overhead wires.
Overhead line is divided into low voltage and high voltage, general model is divided into many kinds, such as street lamp overhead line, JKLYJ*10KVA*50*100, it shows the overhead line voltage, model, material, core cross-sectional area and length.
