A jumper spacer bar is an electrical fixture used to secure and support jumpers in a transmission line to maintain their position and spacing. Jumper spacer bars are usually made of metal and have some mechanical strength and corrosion resistance to adapt to harsh outdoor environments.

The main function of the jumper spacer bar is to prevent the jumper from vibrating and dancing under the action of natural factors such as wind, rain, and snow, so as to avoid short circuit or ground fault between the jumper and the adjacent transmission line or tower. At the same time, the jumper spacer bar can also prevent the impact of external forces such as bird damage and tree barriers on the jumper to ensure the safe and stable operation of the transmission line.

Jumper spacer models and specifications vary according to different use environments and requirements. In general, the choice of jumper spacer rod needs to consider the voltage level of the transmission line, wire type, pitch, wind deviation and other factors. When installing the jumper spacer bar, it is necessary to follow the relevant technical specifications and operating procedures to ensure the installation quality and effect.

In short, jumper spacer is an important part of power transmission line, which is of great significance to ensure the safe and stable operation of the line.
