RAILWAY SPECIAL EARTHING DEVICE U1-SK

The railway special type earthing devices type U1-SK, U1-SK/A, U1-SK/B, U1-SK/C, U1-SK/D, U1-SK/E are designed for earthing overhead traction installation by connecting the auxiliary extension arm of the traction conductor with the railway rail.

Portable earthing devices: U1-SK, U1-SK/A, U1-SK/B, U1-SK/C, U1-SK/D, U1-SK/E are made for currents up to Ir=9kA for time tr=1s. Cross section of wire is 50 mm2. Length of wire can be choose from range 7 – 14 [m] with 0,2 [m] gradation.
The U1-SK railway special type earthing device consists of:
– the WT-Z7 line clamp equipped with a spring-operated self-locking clamp on the extension arm and a spark rod. This clamp co-operates with the head of the TDO-4-B insulating pole,
– earthing conductor made of copper cable with cross-section of 50 mm2
covered with transparent plastic protection,
– the WR-3 earth clamp made of aluminium alloy, the design of which allows to clamp it to the traction rail foot.
