Air break switch NX2004704

Air break switch NX2004704

Overhead switch ISAR-S is installed at the end of the line in a structured MV three-phases 24 kV networks, enables a group of stations to be isolated, so that live line work can be carried out downstream. Delivered in compact packaging, the device has to be assembled in front of the pole: the phases are pre-assembled, the frame, rod assembly and handle are a set of parts to bolt together.
