The invention belongs to the technical field of
power transmission. More specially, the invention relates to a pre-twisted safety
backup wire clamp for suspension, which comprises a hanging point hardware fitting, an insulator, a socket hanging plate, a
power transmission cable, a suspension wire clamp, a
backup stranded wire and an end binding wire. The upper end and the lower end of the insulator are provided with integrally formed sockets, the bottom end and the top end of the hanging point hardware fitting are fixedly connected with the sockets, the
backup stranded wires are bundled and wound on the
power transmission cables at the left side and the right side of the suspension wire clamp, and the end binding wires are used for bundling and winding at the ports of the backup stranded wires, when the power
transmission cable suspension wire clamp is worn and broken seriously, the backup stranded wire can effectively pull cables on two sides of a fracture, so that the problem that the power
transmission cable and the suspension wire clamp are subjected to long-term vibration, abrasion and the like to cause the outer broken strand at the joint is avoided, and the problem that thesudden drop of the wire due to failure in timely discovery or other problems in inspection causes accidents is solved.
