Description:
FZRN21-40.5D Indoor High Voltage Vacuum Load Switch is a type of high-voltage vacuum load switch and LBS-fuse combined unit that is suitable for three-phase AC 40.5kV, 50Hz power system, or supporting with sets of power distribution equipment, RMU switchgear, combined power station, etc.
Application:
FZRN21-40.5D Indoor High Voltage Vacuum Load Switch
is widely used in wind power generation. urban network construction and modification projects, industrial and mining enterprises, high-rise buildings and public facilities.
FZRN21-40.5D Indoor High Voltage Vacuum Load Switch can be used as a ring network power supply unit or terminal equipment with functions such as electric energy distribution, control and protection.
The product's technical performance meets the requirements of GB16926-1997 AC High Voltage Load Switch -- LBS-fuse Combined Unit and IEC420 AC High Voltage Load Switch -- LBS-fuse Combined Unit.
Advantages:
FZRN21-40.5D Indoor High Voltage Vacuum Load Switch
has the advantages as following:
1: large breaking capacity,
2: safety and reliability,
3: Long electric life,
4: frequent operation,
5: compact structure,
6: small in size,
7: lightweight,
8: maintenance-free, etc.
It can disconnect rated current, overload current, short-circuit current and prevent equipment from phase failure operation. The switch has an obvious isolation fracture. It is equipped with a grounding switch and electric spring mechanism with closing and opening ability and can be remotely controlled.
