3-Phase Earthing Device

Ref. SS 428 91 01, EN 61230
Line earthing device JSKL3-STG is for use on overhead transmission lines, low and high voltage 0.4 – 52 kV. The device is equipped with a buttress threaded clamp JSKL-STG. This clamp is tightened against the conductor with a few turns and can be placed diagonally to the line, which significantly simplifies application. Insulating pole MRS, is used to operate the line clamps.
Line clamp’s clamping range: 1-25 mm (Cu 10 mm2 – FeAl 329mm2). The device has a rubber insulated bayonet type connector fit-
ting for connecting an alternative earthing device such as JSKL1-STG and JSKL1-JTG and earthing device JK238-DXF, JK250-DXF.
The line clamps conducting parts are made of hardened AlSi-alloy. Steel components are surface treated. 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 to the clamp with a cable lug.
Case: DFO/JSKL1-J.
