CONSTRUCTION AND APPLICATION:

Distribution box 88.3000-BHV is a sub-assembly of the ZW-1 (BHV) coupler assembly used to connect individual railcar segments of a train’s high voltage heating systems. The box task is to permanently connect HV cables. The box housing is made of  aluminum alloy is equipped with internal terminals for HV cables mounted on an insulating bracket. HV cables are mounted in a clamp and pressed by three shins. Rubber packing within the box gland may be replaced to match the used ASWP cable gauge.

 

The box is fixed to the locomotive or a railcar by means of two M20 bolts.

The box is equipped with two grounding elements: an M12 bolt outside the box body; an M10 bolt inside the body (for cables of the ASWP type).


 The construction is TOTALLY INSENSITIVE to shocks and vibrations that accompany a train ride AS WELL AS TO MOISTURE AND POLLUTION.
