描述:
The 400kV Gas Insulated Switchgear (GIS) is a compact, metal-enclosed switchgear assembly designed for extra-high-voltage transmission substations up to 420,000 volts. Using SF₆ gas as the primary insulating and arc-quenching medium, it integrates all live components in a sealed, maintenance-reduced enclosure. The system offers high reliability and a reduced footprint compared to conventional air-insulated designs.
概观:
Rated voltage(kV)420kV
Short-circuit current rating(kA)50kA/63kA/80kA
Rated current(A)Up to 6,300A
Rated frequency(Hz)50/60Hz
Features
  • Ensures stable quality thanks to condenser-free breaking parts.
  • Secured with large-capacity breaking performance.
  • Excellent reliability with mechanical durability (class M2) and small capacitive current (class C2).
  • Guaranteed gas leakage rate of less than 0.1%/year.
