JW10 Earthing Switch
JW10 Earthing switch is used to release the static charge of the line and equipment to be repaired. The high-voltage equipment such as the bus bar and circuit breaker to be repaired is electrically safely grounded, so that the grounding opening and closing mark is clearly visible in the line to ensure the personal safety of the maintenance personnel.

01
Advantages of conductors
Conductive arm made of high strength aluminum alloy profiles, with good electrical conductivity, high strength, light weight and excellent anti-corrosion ability.

02
Advantages of design structure
The earthing switch has a one-step action structure and a snap-in contact, which is simple in structure and easy to maintain. The structure effectively uses electric power to clamp the contacts and keep the ground knife in the closing position, so it has excellent ability to withstand short circuit current.

JW10-363, 420, 550, 800 type ground switch is single-arm vertical open structure, contact is inserted, simple structure. The grounding conductive rod is a two-step action when opening and closing. When closing, rotate from horizontal upward to the static contact, and then move straight upward to play the plum contact, and the ability to withstand short circuit current is strong.
