Type: 804.001-M

for subway (underground)

Short-circuiting (earthing) set designed for short-circuit making and earthing of power supply distribution of subway’s rail set. The set is designesd for the nominal network voltage of 1 kV.  The short-circuiting set is delivered together with one conductor clamp of special contruction, one earthing clamp and Cu cable in transparent insulation. It is possible to connect conductor clamp to supply rail and earthing clamp to driving rail. The handle of conductor clamp is provided with the protecting ring (hand guard). The side handle serves for better manipulation with set and it is removable. The material of set fulfills the requirements on the protection equipment for outdoor use.
