VFZN25-12D/T630-20 indoor AC H.V. load break switch is the indoor installation with tri-phase AC 50HZ, rated voltage 12KV, which is suitable for using in industry and mining situation and so on enterprise substation and transformer substation. As protection and controlling the electrical facility, using in Off and On load current, closed loop current, idling transformer and cable charging current. It has manual and electrical motor operating mechanism that is advantageous to realize three remote controls requirement of power system.
VFZRN25-12D/T125-31.5 indoor AC H.V. vacuum load break switch fuse combined electric appliance is the indoor installment with tri-phase AC 50Hz, rated voltage 12kV, which is suitable for load control and short circuit protection using in industry and mining situation and so on enterprise substation and transformer substation. It is equipped with an earthing switch that may withstand short-circuit current. The operating mechanism can be possible manually and electrically operated that is advantageous to realize three remote controls requirement of electrical power system.
VFZN25- 12D, VFZRN25-12D load switch and combination electric appliance are suitable for load control and short-circuit protection, using in urban power station and industrial electric appliance supply by tri-phase ring network or terminal. For the protection of combined electric appliance on electrical appliance equipment is more reliable, economical than circuit breaker electrical appliance equipment such as the transformer, especially is for the ring net, double radiation power supply unit and box type transformer substation.
