DNK High Voltage 12KV Load Type Falling Fuse with Arc Extinction Equipment

Description

    In addition to the function as a fuse used in power distribution system the SSOC (NCF)3 fuse can be also applied as the outdoor load switch equipped with an independent arcing chute for loadbreak which restricts the electrical arc and provides de-dissociation function.

High Quality Material Fuse tube - epoxy fiber glass with fiber lining coated with special ultraviolet resistant material, the corresponding disconnect switch knife can be here selected.

     2.    Upper contact - silver to silver, high contact pressure squeezed by stainless steel spring.

            

  3.     Trunnion - high strength cast copper, silver - plated, and pressed on the side surface of the hinge around the trunnion surface to ensure the fuse tube alignment while switching-on.
