DFP Type 12/24/35kv Outdoor Cable Distribution Box

DFP Type 12/24/35kv Outdoor Cable Distribution Box

Outdoor Cable Distribution Box

Product Introduction

DFW type cable distribution box is a kind of outdoor high-voltage electrical equipment of that rated voltage is 12/24 / 35kV, rated current is 630A , for the connection and cut of power cable.

Structure features 

This products adopts "high-performance hexafluoride load switch with SF6 insulation gas inside" and "shielded silicon rubber cables separable connector", with strong drop-out ability of active load and no-load cable current and strong closing ability of short-circuit current, what's more, we can install lightning arrester and ground fault indicator according to users' request.

Each ring connecting lines of this series of products are equipped with vacuum load switchgear or circuit breaker, any branch circuit is free to withdraw and put into operation, and other ring circuits are not affected; can install extra fuse on load switch, when one branch circuit has short-circuit accident, the fuse in this branch circuit can break accident circuit immediately, and impact load switch's release to let it trip, isolate accident circuit, which can ensure non-accident circuits' continuous power supply.
