40.5kV composite combined electrical apparatus (HGIS) is an outdoor three-phase AC power transmission equipment using SF6 gas as the insulating medium. The product structure consists of components such as inlet and outlet bushings (BSG), three (multi) position isolating grounding switches (DES), circuit breakers (CB), and current transformers (CT). It can meet the needs of different substation designs through flexible combinations of these modules, which not only saves space but also simplifies substation design work. It has the advantages of small volume, small footprint, large configuration flexibility, simple maintenance, and long cycle.
