Branching boxes are intended for connection and branching of flexible and armored cables, wires with copper and aluminum cores at mining enterprises of
ferrous and nonferrous metallurgy. Environment is not explosive.
Great cross section of laid cable cores.
The box is intended for RN area.
The body has four incoming devices ensuring sealing of flexible cables with outside diameter from 24 to 52 mm (cross section of cable cores from 6 to 70
mm2) and device for box pendant mounting. Cables are fixed by means of special bushings ensuring unloading of cores from tension forces and twisting.
body six clamps are installed connected with busbars by pairs intended for power circuits and three grounding clamps connected by busbars. Clamps intended for power circuits
are designed for connection of cable cores with and without caps.
