Overview

FKN12-12D compressed air load switch, FKRN12-12D series compressed air load switch-fuse combination electrical appliances are new series of switchgear developed by our company, suitable for 12kV and below three-phase power distribution system, as transformer, cable, overhead It is used for control and protection of power equipment such as lines; it is especially suitable for terminal substations and box-type substations of urban and rural power grids. And it is suitable for the control and protection of ring network and double radiation power supply unit.

FKN12-12D series pressure load switch can switch load current and overload current.

FKRN12-12D series compressed air load switch ~ fuse combination can switch load current, overload current, and break short circuit current.

This series of products has the characteristics of compact structure, reasonable design, reliable interlocking and high insulation level; the spring energy storage operating mechanism makes the opening and closing speed not affected by the operator's operating force; the arc is extinguished in the bell-shaped insulating cover , the free gas during arcing will not cause the reduction of the dielectric strength between phases or to the ground. The use of copper-tungsten alloy arc ignition needle and plum-shaped main contact makes the switch reliable in conduction and long in electrical life. This series of products is easy to maintain, easy to operate and reliable in operation, and has won praise from users.

This series of products is designed and manufactured in accordance with the following standards:

GB3804 "3-63kV AC High Voltage Load Switch"
GB16926 "AC High Voltage Load Switch Fuse Combination Electrical Appliances"
GB1985 "AC High Voltage Isolation Switch and Earthing Switch"
IEC265 "High-voltage load switch with rated voltage above 12kV and below 52kV"
IEC420 "AC High Voltage Load Switch-Fuse Combination Electrical Appliances"
