The 35kV high-voltage gas insulated switchgear is a high-grade compact power distribution equipment independently developed by Mingtuo Electric for 35kV high-voltage power transmission and distribution systems. It inherits the core advantages of full insulation, full sealing and IP67 high protection of the series products, and upgrades the internal insulation structure and bearing capacity, adapting to high-voltage and large-current power supply scenarios. The product has excellent short-circuit resistance and fault tolerance, with more stable dielectric performance. It is widely used in new energy power stations, industrial high-voltage power distribution, suburban power grid trunk lines, box-type substation matching and other high-reliability power supply occasions, realizing safe, stable and maintenance-free long-term operation of high-voltage power distribution links.
