1.In order to reduce the induced voltage and power loss of the overhead ground wire, the ground wire is insulated from the ground, and only a grounding of a certain base tower of the line is called grounding at a single point. When the overhead grounding wire is grounded at a single point, the tower of the grounding point should ensure that the grounding wire is r...

The requirements for the 110KV overhead line are: 1 to meet the current capacity requirements; 2 to meet the tensile strength requirements of the wire under various conditions. Since the three-phase wires of the overhead line are separately erected on the line pole, the distance between the three wires has already met the insulation require...
