DFW 10kV cable branch box
Product Details
Product overview
DFW series high-voltage cable distribution box, widely used in 35KV, 25KV, 10KV cable system node connection, is the main electrical equipment for collection and distribution of cables after outgoing from the switch cabinet. The cable joint of the tap box adopts high-grade insulation imported rubber tight covering insulation without exposed charged body; the switch with switch tap box adopts SF6 insulated load switch.
