With China's electrified railways demanding switchgear to be more compact, intelligent, maintenance-free, and operable under all conditions, the high-quality GSR6-27.5 series environmentally friendly gas-insulated metal-enclosed switchgear (C-GIS) has been developed. This product uses dry air (D-air) as the insulating medium and integrates vacuum circuit-breaking technology, APG solid-seal technology, gas insulation technology, and interface insulation technology, making it a green and environmentally friendly medium-voltage switchgear for railways. The product has passed type tests and technical appraisal by national authoritative testing institutions. Its design is mainly suitable for single-phase or two-phase electrified railway systems with a rated voltage of 27.5 kV and a maximum voltage of 31.5 kV, such as high-speed railways and dedicated passenger lines, as well as other advanced railway applications.
The product features a modular design, allowing solutions to be flexibl
