1-Phase Earthing Device
Ref. SS 428 91 01, EN 61230, EN 61235
Earthing device JSGO or JSGO-T is used in combination with line earthing device JSGT.
Line clamp’s clamping range: 3-20 mm. The device has a rubber insulated bayonet type connector fitting for connection to earthing device
JSGT and JSGH.
The line clamp conducting parts are made of hardened AlSi-alloy. Steel components are surface treated. The insulating pole is made of
fiberglass reinforced vinyl ester and is sealed. The earthing cable, made of highly flexible ESTPR-insulated copper strands, has sealed cable connections, which prevent humidity from penetrating the cable. The earthing cable is connected by compression to the line clamp (also available with cable lug connection).
As standard the earthing device is marked with 24 kV.
