Product Description
Each technical performance index outdoor high voltage isolating vacuum load switch completely reachedGB3804 and IEC standards. It is suitable for power supply network with rated voltage of 12kV, rated current of 630A and 3-phase AC 50Hz and used for closing and opening load current.
Ambient temperature:+40ºC~-30ºC;
Altitude above sea level not exceed 2000m;
Relative humidity : Daily average value not exceed 95%,Monthly average value not exceed 90%;
No frequent extreme vibration.
Using vacuum arc extinguishing chamber, no explosion danger, no maintenance.
The isolation knife is connected with the three-phase vacuum interrupter, and the isolation fracture is visible when the brake is opened.
All parts of the body are made of stainless steel, and the bottom frame is made of carbon steel with hot dip galvanized plus ultraviolet protection coating to ensure the normal operation of the body in outdoor environment.
The installation mode is mainly single-pole operation, which can be operated manually, electrically or remotely.
Widely used in rural power grid, urban network, railway and other configuration line transformation.
Large breaking capacity, safe and reliable, long electrical life, frequent operation.
