F KN12A-12 (D )/T630-20 FKRN12A-12 (D )/T125-31.5 AC high voltage gas production load switch/High voltage load switch-fuse combination
FKN12A-12D gas production load switch, FKRN12A-12D series gas production load switch-fuse combination electric appliance, is a new series of switches and equipment developed by our company. It is suitable for 12KV and below three-phase power distribution system, as transformer, cable and overhead. It is used for the control and protection of power equipment such as lines; it is especially suitable for terminal substations and box-type substations in urban and rural networks. It is also suitable for the control and protection of ring networks and dual radiant power supply units.
FKN12A-12D series gas production load switch can divide load current and adoptive 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 unaffected by the operator's operating force; The arc is extinguished in the bell-shaped insulating cover, and the free gas during arcing does not cause a decrease in the insulation strength between the phases or the ground. Adopting the arc-ignition needle and plum-shaped contact of copper-tungsten alloy, the switch is reliable in conduction and long in electrical life. This series of products is easy to maintain, easy to operate, reliable in operation, and won praise from users.
