Jumper spacer bar

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.

Double split spacer rod is a special spacer rod, mainly used in double split wire system. In power transmission lines, double-split wire system is a common wire arrangement in which two wires are arranged in parallel to improve transmission capacity and reduce corona loss. The function of the double split spacer is to hold and support the two wires in this wire system, maintaining the spacing and relative position between them.

The design of the double split spacer should consider the diameter of the wire, the spacing, the mechanical properties of the material and the environmental factors. It needs to have enough strength and stability to withstand the tension of the wire and the influence of the external environment, such as wind and rain, temperature changes, etc. In addition, the double split spacer rod also needs to have good electrical performance to prevent the occurrence of electrical failures.

In the double split wire system, the installation position and number of the double split spacer rod also need to be designed according to the specific engineering requirements. Reasonable installation position and quantity can effectively ensure the stability of the wire and transmission efficiency.

In short, the double split spacer is an indispensable part of the double split wire system, and its design and selection is of great significance to ensure the safe and stable operation of the transmission line and improve the transmission capacity.
