The current practice in China is that the operators use insulating blankets to insulate and shield the adjacent phase wires, hanging porcelain bottles and tension cross arms, and then use insulating jack ropes to fix the insulation tensioner and backup protection rope clamps to the angle steel cross arms. connect. Specifically, one end of the jack rope is placed on the double cross arms of the fixed hanging porcelain bottle wrapped with an insulating blanket, and the other end of the jack rope is fixedly connected with the insulating wire tightener or the protective wire clamp. During the operation process, the jack rope rubs frequently at one end of the double-angle steel cross-arm. After a long time, the jack rope will be greatly worn. If you continue to use it, it will affect the tensile strength of the jack rope, thereby affecting the safety of the jack rope.
