| Rated voltage | 800KV |
| Series | JW |
Description
JW5 series high voltage earthing switch is composed of three single poles and operating mechanism. Each single pole consists of a base, a pillar insulator and a conducting rod. The conductive rod is installed on the base, and the static contact is installed on the top of the pillar insulator.
The operating mechanism drives the conductive rod to rotate upward from the horizontal position through the transmission element, and is stuck or inserted into the static contact to realize the closing of the ground switch, and the opening process is the opposite.
Main Features
The product structure is simple and reasonable, easy to assemble, transport, install and debug.
The conductive rod is made of high-strength alloy profiles with good electrical conductivity, high mechanical strength, light weight, strong anti-corrosion ability and long service life.
