3-Phase/2-Phase Earthing Device

Ref. SS 428 91 01, EN 61230, EN 61235
Line earthing device JSKL3-QL is for use on the Railways auxiliary power lines.
Earthing device JSKL3-QLBV is equipped with a quick-lock clamp JSKL-QL. This clamp is tightened against the conductor with just one turn. Earthing device JSKL3-TGBV is equipped with buttress threaded clamp JSKL-TG. This clamp is tightened against the conductor with a few turns. JSKL-QL and JSKL-TG can be placed diagonally to the line, which significantly simplifies application.
Line clamp’s clamping range: 1-25 mm (Cu 10 mm2 – FeAl 329 mm2). The devices are equipped with an earth clamp JK 238. Earth clamp JK 238 is for connection to steel structures such as frameworks and bars with a thickness up to 30 mm. The clamp is approved for use on painted surfaces and can also be connected to the base of the rail, which allows rail vehicles to pass.
The line clamps 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. Conducting parts of the earth clamp are made of surface treated spring steel with hardened spikes. Other steel components are made of stainless steel. The loop is made of spring steel to give a constant contact pressure. The screw is insulated. 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 clamps with cable lugs. As standard the earthing devices are marked for 24 kV.
Also availably in a 2-phase design, JSKL2QLBV/25 alt. JSKL2-TGBV/25.
