Structure and performance


The GN□-12D cable-side grounding disconnector has a novel structure and is a new type of disconnector independently developed by the company. The moving and static contacts are installed on two parallel insulators. It has small installation space, convenient busbar connection, obvious fracture, and is suitable for various installation heights. Grounding on the side of separate and protective outgoing cables.
