Short-circuiting (earthing) equipment HV 38.5 kV – universal – outdoor – single-phase

Type: 824.040 1F

Models: 824.040 – 06 (08,10,15)

Short-circuiting (earthing) set is designed for short-circuit making and earthing of the circuit in networks with an indirectly earthed or insulated node of the nominal voltage of up to 35 kV. The short-circuiting set is delivered together with one insulating pole ended with conductor clamp, which is connected by Cu cables in transparent isolation to the earthing clamp. Conductor clamp is universal, i.e. for connection to conductor of circular cross section, spherical connecting point, connecting point of “T” shape or to the flat conductor. Earthing clamp is connected to the earthed flat conductor or to the conductor of circular cross section. Insulating pole is made of glass fabric laminate which is suitable for its high electrical and mechanical resistance and stability. It fulfills the equirements on the protection equipment for outdoor use. The set is determined for indoor use, as well as for outdoor use under normal climatic conditions. The handle is provided with the protecting ring (hand guard). Short-circuiting set complies with standards ČSN EN 61230 ed.2, IEC 61230, DIN 46235. It is produced in four models for various short-time withstanding current. It is possible to modify the model at the custom’s request.
