FN7-12R(L)AC MV load switch used in 50Hz,12kV three phase AC power system
FN7-12R(L)series vacum circuit breaker is indoor high voltage switch-gearwith rated voltage 12kV,three-phase AC 50Hz,which is developed by introducing from Switzerland,ABB corporation technology and analyzing domestic professiondevelopment condition,productivity development manufacture product.The overaltructure of this product is formed with theswitch mainbody and operating device,uses the compound insulation structure,does not have the pollution and the explosionhazard,and the insulation level is high.This operating device of the series product is for the spring loaded type,can use theelectrically operated operation,also can use the manualoperationc Standard:IEC 60265-1,IEC62271-105.

FZN25,FZRN25 vacuum load switch and composite apparatus,suitable for three-phase AC 50Hz ring network or terminal power supply and industrial electrical equipment,for load control and short circuit protection use,load switch open and close the closed loop current,no-load transformer and cable charging current,composite apparatus can break any current till ated short circuit current

The FZW28-12 outdoor sectionalizer vacuumload switch is equipped withfault detection,protection,control and communication functions that can autonomously isolate single-phase grounding faults and automatically isolate phase-to-phase short-circuit faults.Itis suitable forthe incoming end oruser end of 10kV distribution lines and can alsobe used at otherbranching line connections that meetthe requirement

FZW32-12 (40.5)outdoor MV isolatingvacuum load switch is a newtype of load switchwhich is the integration of mature experience of domestic existingload switch and advancedtechnology design of external.This load switch is composedof isolating switch,vacuum interupter and operating mechanism and other parts.By using the principle ofvacuum interrupter,with strong arcing ability,reliableperformance,long service life,small volume,no explosion danger,no pollution etc advantage.Theproduct can be used in transmission and distributionsystem ofelectric power,metallurgy,mine,chemical industry and other departments as control equipment,especially suitable for frequent operation place
