1-Phase Earthing Device
Ref. SS 428 91 01, EN 61230, EN 61235
Earthing device JSKL1-QL/-TQL is used in combination with line line earthing device JSKL3.
The device is equipped with a quick-lock clamp JSKL-QL. This clamp is tightened against the conductor with just one turn and 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). Thedevice has a rubber insulated bayonet type connector fitting for connection to line earthing device JSKL3-QL.
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 to the clamp with a cable lug. As standard the earthing device is marked for 24 kV.
