Type: 812.245
Models: 812.245 – 10 (15, 19)
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 220 kV. The short-circuiting set consists of three insulating poles ended with fixed conductor clamps for the attachment to conductor of circular cross section up to 50 mm in diameter and three short-circuiting cables ended with universal earthing clamps. 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. Pole consists of two pieces connected by means of connecting element. 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. It is possible to modify the model at the custom’s request.
