In the prior art, each sub-conductor is mainly supported by a spacer in the power transmission line in China, and when the power transmission line is used, the spacer is arranged between the sub-conductors of each power transmission line, and collision between the sub-conductors is prevented through the effect of the spacer. The common spacer comprises a frame body and a wire clamp connected with the frame body, wherein the wire clamp is also used for being connected with the power transmission line. In general, the wire clamp and the power transmission line are directly clamped, and the like, so that in the connecting mode, the wire clamp is directly clamped on the power transmission line, the abrasion to the insulating layer of the power transmission line is large, when the wire clamp is subjected to downward tension, the local stress is easily concentrated, the voltage transmitted by the power transmission line is relatively high, and if the power transmission line is subjected to large local stress, a great potential safety hazard exists.
