Problems solved by technology
[0002] Since the long-term operation of the transmission line has to withstand the severe test of severe weather such as ice, snow, and storms, the original high-voltage transmission line jumper spacer has a reasonable mechanical strength, damping performance, corrosion resistance and appearance. There are certain defects in the performance, there will be whipping and collision between the wires, and sometimes the wires also have vibration problems

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0021] As shown in the figure, this squirrel-cage type jumper spacer has a wire splitting distance of 300mm, and the applicable wire diameter range is ￠22-35mm. It mainly includes a frame 1 and a clamp body 2. The frame 1 is divided into two symmetrical parts. Through the connecting hole 22 on the frame 1 , the second bolt 13 , the second flat washer 14 , the second spring washer 15 , the second nut 16 and the second cotter pin 17 are fixedly connected together. The first mounting hole 19 provided on the frame 1 and the second mounting hole 23 provided on the clamp body 2 pass through the first bolt 7, the first nut 8, the first flat washer 9, the first spring washer 10 and the first A cotter pin 11 fixedly connects the frame 1 with the ends of a group of clamp bodies 2 along the circumferential direction, and the first bolt 7 is covered with ...

The invention relates to a squirrel-cage jumper spacer, comprising a frame and a wire clip body. The frame is formed by splicing two symmetrical parts. The frame is respectively fixedly connected with the ends of a group of wire clip bodies along the circumferential direction. A rubber stopper is clamped at the connection with the wire clip body, the front end of the wire clip body is provided with a first pin hole, the first pin hole is separated and forms a slot, one end of the cover plate is inserted into the slot, and the cover plate is inserted into the slot. The second pin hole and the first pin hole are connected together by a hinge pin; the clip body and the cover plate are provided with a rubber pad cavity for installing the rubber pad, and the clip body is provided with a self-locking pin that cooperates with the locking pin hole. The beneficial effects of the invention are: the product is a squirrel-cage jumper spacer for 750KV high-voltage transmission lines, which mainly splits the wires, supports the overall squirrel cage shape, prevents whiplash and collision between the wires, and has the function of suppressing the vibration of the wires .
Description
technical field [0001] The invention relates to the field of high-voltage transmission lines, in particular to a squirrel-cage wire jumper spacer. Background technique [0002] Since the long-term operation of the transmission line has to withstand the severe test of severe weather such as ice, snow, and storms, the original high-voltage transmission line jumper spacer has a reasonable mechanical strength, damping performance, corrosion resistance and appearance. There are certain flaws in the performance, there will be whipping and collision between the wires, and sometimes the wires also have vibration problems. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming of above-mentioned technology, provide a kind of squirrel-cage jumper spacer. [0004] The technical solution adopted by the present invention to solve the technical problem is: the squirrel cage type wire jumper spacer includes a frame and a clamp body, the fr...
