Description

Technical Field

[0001] The utility model relates to the technical field of power accessories, in particular to an overhead insulated wire clamp. Background Art

[0002] When the cables are routed overhead, in order to prevent the cables from getting entangled with each other, wire clamps are used to juxtapose the cables. The most traditional wire clamps are composed of an upper clamp, a lower clamp, bolts and nuts. The upper and lower clamps are connected, the bolts are inserted between them, and the nuts are tightened to tighten the cables in the upper and lower clamps. However, in the process of tightening the cables, we will find that one of the clamps will deflect during the process of tightening the bolts, resulting in misalignment between the upper and lower clamps, which will indirectly squeeze and break the cable and affect the service life of the cable.

[0014] 1. The overhead insulated conductor clamp is provided with an upper telescopic joint between an insulating lower clamp and an insulating upper clamp.
