High-voltage GIS composed of components such as circuit breakers(CB), busbars, disconnecting switches, voltage transformers, current transformers, lightning arresters, bushings, and grounding switches. It employs SF6 gas with outstanding insulation and arc-extinguishing performance as both insulation and arc-quenching medium, and seals all high-voltage electrical components within a grounded metal enclosure. Suitable for power grids with high voltage levels and large capacity ratings, it serves for power reception/distribution and control.

Features: compact structure, small footprint, high reliability, flexible component arrangement, convenient installation, strong safety, robust environmental adaptability, and minimal maintenance workload.

Voltage levels: 126kV, 252kV
