Purpose Of Insulator Binding Wire

‌The main purpose of insulator binding wire includes fixing the conductor, preventing the conductor from contacting with pillars, hardware, etc. to cause short-circuit faults, and bearing the tension of the conductor to maintain the normal shape and position of the conductor. Specifically:

‌Fixing the conductor‌: Insulator binding wire is used to fix the conductor to the insulator to ensure that the conductor does not move or fall off at will. For example, on a straight pole, the conductor should be fixed in the groove at the top of the pin insulator; on a corner pole, the conductor should be fixed in the groove of the binding wire outside the insulator corner.

‌Preventing short-circuit faults‌: The binding wire can isolate the conductor from metal parts such as pillars and hardware, preventing the current from flowing back to the ground through these metal parts, thereby avoiding the occurrence of short-circuit faults.

‌Withstanding tension‌: The binding wire can withstand the tension of the conductor, maintain the normal shape and position of the conductor, and ensure the stable operation of the transmission line.

In addition, there are specific requirements for the length and fixing method of the binding wire. For example, when copper wires are fixed on butterfly insulators, the binding length needs to be determined according to the cross-sectional size of the wires. Aluminum wires are prone to wear at the contact points with insulators and hardware, so aluminum tape needs to be wrapped around the contact points to protect the wires.
