Description

Technical Field

[0001] The utility model relates to an electric power fitting, in particular to a novel pre-twisted phase-to-phase spacer fitting. Background Art

[0002] Phase spacers are essential protective fittings for the State Grid's main transmission and distribution line fittings, which are used to maintain the phase distance between conductors and suppress conductor dancing.

[0003] The interphase spacer structure mainly includes the middle spacer tile and the spacer clamp. When the interphase spacer is used in extremely cold weather, the middle spacer tile plays the role of shock absorption and clamping the wire. It is generally made of rubber and is prone to cracking and falling off due to freezing. This can easily cause strong friction and collision between the wire and the spacer wire clamp when the wire dances in strong winds, causing risks such as wire damage and spacer breakage, which may cause the circuit to lose power due to broken wire strands, causing safety hazards such as fire and explosion, affecting the stable operation of the transmission line, and directly causing economic losses.

[0008] The spacer pad comprises a rubber body, in which two parallel frames are arranged, and the frames are in a shape of inferior arc.

[0009] A connecting column is arranged in the middle of a pair of frames.

[0010] The frame is made of metal.

[0011] A positioning groove is provided in the middle of the C-shaped hole, and a positioning block is provided in the middle of the outer side of the spacer pad.

[0012] The positioning block is used to be connected in the positioning groove.
