Short-circuiting (earthing) equipment VHV 123 kV – for conductors 0 – 50 mm

Type: 810.123

Models: 810.123 – 10 (15, 19) H (S), 810.123 – 10 (15, 19) D, H (S)

The short-circuiting (earthing) equipment is designed  for short-circuit making and earthing of the circuit in networks with an earthed  node of the nominal voltage of up to 110 kV. The short-circuiting set consists of one insulating pole and three short-circuiting cables ended with conductor and universal earthing clamps to connect it to the conductor of circular cross section up to 50 mm in diameter. Conductor clamps are connected to earthing clamps by Cu cables in transparent isolation. Insulating pole is made of glass-fabric laminate which is suitable for its high electrical and mechanical resistance and stability. Upper part of pole is ended with hook (model H) or socket (model S) to connect of conductor clamp. It fulfills the requirements on the protection equipment for outdoor use. The set is determined 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 three models for various shorttime withstanding current with the pole in all or divided. It is possible to modify the model at the custom’s request.
Note: Insulating pole can be delivered divided to two parts for models 810.123-10(15,19)D. Poles are connected by means of connecting element.
Example of order: 810.123-19,D,H = set with short-time withstanding current 19 kA / 1 s, with hook and clamp 810.020, divided pole.
