The tower will be set up in a high wire power transmission line. Forhigh voltage transmission distribution network overhead lines to groundinsulation is generally rely on air, before the distribution line (below10 kV in 380V) is also generally used bare wire, but due to thecomplexity of the urban distribution environment, often short-circuitground and lightning, resulting in reduced the reliability of powersupply, so the current general 10KV overhead lines use insulated wire(wire coated with insulating layer), this is the so-called insulationoverhead power lines.

Overhead lines with low pressure and high pressure points and models are generally divided into many kinds, such as street lamp overhead line, JKLYJ*10KVA*50*100, it shows that the voltage of overhead transmission line, types, material, core of the sectional area and length of the.
