3-Phase Earthing Device
Ref. SS 428 91 01, EN 61230
The device is for use on substations.
Line clamp JK 42 is for connection to contact fittings JKA, JKC, JKAD, JBA, and JBC or directly on lines or pipes with max Ø 40 mm. Insulating poles MGV, MDV/MSV and operating socket JGS are used to operate the line clamps.
The line clamps conducting parts are made of hardened AlSi-alloy and steel components are made of stainless steel. The thread has a Heli-Coil insert in stainless steel. 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 earthing device. Cable shoe JLA 34 is made of hot pressed electrolytic copper and the hand bolt of stainless steel.
