General
SF6 Gas Insulated Metal-clad switchgear, RGIS-G20 designed up to 40.5kV 3-phase 3 wire 50/60 Hz system.
The switchgear voltage rate up to 40.5kV and has horizontally or Vertically-installed vacuum circuit breakers.The switchgear includes vacuum circuit breakers, meters, relays, etc. The switchgear is certified by Xi'an High Voltage Institute.

Features
Compactness, Automation,
High Reliability and Safety, Easy Expansion,
Simple Installation, Economy.
Stationary Structure
The switchgear consists of bus compartments and a circuit breaker compartment that are hermetically pressure sealed with SF6 gas.
●Welded stainless steel enclosure
●Modular design
●Duct for pressure relief
●Panels coupled by plug in bus connectors
●Cable connection inner cone plug in system

Environmental Qualification
in order to simplifying the switchgear equipment maintenance and extending service life,We analyzed the test data and upgraded the product.
Hermetically-sealed primary enclosure for protection against environmental conditions (dirt, moisture,  vermin, insects and high altitudes).

Quality Assurance
The program comply with the requirement ofISO fully.
