Overhead line is a line which is erected by tower to transmit
electric energy at a certain height. For the high-voltage
transmission and distribution network, the ground insulation of the
overhead line is generally based on air, and the distribution line
(except 380V under 10kV) generally uses bare conductor. However,
due to the complex urban distribution environment, short-circuit
grounding and lightning strike often occur, resulting in the
decrease of power supply reliability. So far, the overhead line
under 10kV generally uses insulated conductor (that is, the outer
layer of conductor is wrapped with insulation layer), which is the
so-called insulated overhead cable.
