3-Phase Earthing Device

Ref. SS 428 91 01, EN 61230
Line earthing device JSKL3-SQL is for use on overhead transmission lines, low and high voltage 0.4 – 52 kV. The device is equipped with quick-lock clamp JSKL-SQL. This clamp is tightened against the conductor with just one turn and can be placed diagonally to the line, which significantly simplifies application. The earthing device is as JSKL3-SQL but prepared for a 5:th clamp. Insulating pole MRS, is used to operate the line clamps.
Line clamp’s clamping range: 1-25 mm (Cu 10 mm2 – FeAl 329 mm2).
The device has a rubber insulated, bayonet type connector fitting for connecting alternative earthing devices such as JSKL1-SQL and JSKL1-JQL and earthing device JK31-DXF, JK238-DXF, JSGO.
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.
