Detailed Product Description

 

FZN25 -12RD/T12.5-31.5 indoor AC high-voltage  vacuum  load  switch ,which is also named ZFN25 load switch , is  the triphase high voltage switch equipment of  10kv rated voltage and 50HZ rated frequency .It is used to close the load current ,closed loop current , unload transformerand cable charging current and combine short current. Load switch of the Earthing .switch is also equipped ,which can stand load current. In order to realize the demand of tri-control of electrical power system engineering , hand operation and motor operation system are equipped.
FZRN25 vacuum load switch and group machine can be used in power supply  power equipments of triphase AC50HZ ring net or commercial power which can control lead and short circuit. It is used in opening and closing load current, closed loop current, unload transformer and cable charging current .Group machine can be opened to any current of rated short current. The linkage of direct acting isolation clearance and vacuum arcing chamber is adopted. It has the unction of hand operation and electricity operation.

FZRN25 has special design. Vacuum arcing chamber only stand voltage at the moment of opening and closing, so the size is small and the price is low.

FZRN25 can realize one off operation of isolation clearance and are extinguishing chamber clearance.

FZRN25 mutual-linkage grounding valve of grounding switch between static contact and moving electric torch, so it can make sure safety and convenient maintenance

Equipments of triphase AC50 HZ ring net or commercial power which can control lead and short circuit. It is used in opening and closing load current,closed loop current, unload transformer .
