Welding Type Power Cable Joint

2022-10-20
Overview

Welded cable joint has the characteristics of good waterproof performance, excellent electrical conductivity, reliable insulation performance, and no partial discharge phenomenon, high voltage, small volume, long service life. It's different from Heat Shrinkable Cable Accessories.

It is a cable accessory whose electrical and mechanical properties are closest to the power body. The product passed the test of National Wire and Cable Quality Testing Center and met the requirements of GB/T12706.4 national standard.

Welding Type Power Cable Joint is a new cable connection mode. It's our company independent research and development, with independent intellectual property rights of power cable connection technology. Welded cable joint has the characteristics of good waterproof performance,excellent electrical conductivity, reliable insulation performance, and no partial discharge phenomenon, high voltage, small volume, long service life. 

It is a cable accessory whose electrical and mechanical properties are closest to the power body. The product passed the test of National Wire and Cable Quality Testing Center and met the requirements of GB/T12706.4 national standard.

Weld type power cable joint, the conductor connection adopts aluminum exothermic welding, so that the conductor is welded together completely, so that the cable restores its original structure, does not change the original characteristics of the cable, the service life of mechanical and electrical performance is equivalent to the original cable.
