Product Overview
GPN2-40.5kV cubicle type gas insulated switchgear (CGIS) is an indoor, factory-assembled, metal-enclosed switchgear for 40.5kV single busbar applications. It is available in three versions to suit different insulation and environmental requirements.
GPN2E-40.5 — Green Type
Mixed gas insulated (SF6+N2) with vacuum breakers, reduced SF6 by 50%.
GPN2N-40.5 — SF6-Free Type
Pure nitrogen insulation, zero SF6 emission, genuine green environmental protection.
Key Features
Reduced Greenhouse Gas Emissions
Available with 50% or 100% SF6 reduction using nitrogen mixed gas or pure nitrogen insulation technology.
70% Reduction In Switchroom Size
Optimized electric field design results in compact switchgear saving 70% space vs air-insulated switchgear.
Reliable Electrical And Mechanical Interlocks
Interlocks between circuit breaker and three-position switch prevent misoperation.
Maximum Operator Safety
Minimum functional pressure 0.00 MPa (20℃); rated insulation level maintained even under gas leakage conditions.
Easy Installation And Extension
Modular panel design with plug-in connectors; middle panels removable for maintenance without moving neighbouring panels.
Low Gas Pressure Operation
Operates normally at zero gauge pressure; switchgear can remain energized even if gas escapes.
Vacuum Switching Technology
Arc limited in vacuum interrupter, reducing insulation gas exhaust volume; high performance in frequent switching applications.
Embedded Pole VCB Design
Three-phase embedded poles arranged vertically in circuit breaker gas tank; APG epoxy molding process for high insulation level.
Suitable For Harsh Industries
Suitable for power networks, mining, rail transportation, petrochemical plants, wind farms, and metropolitan rail systems.
Digital Manufacturing And Auto Testing
Modern digital manufacturing with automatic testing coupled with sensor, monitor and protection technology.
Easy Retrofitting
Can be retrofitted into existing switchroom; reduces cost of substation land.
IP65 Gas Tank Protection
Gas tank rated IP65; enclosure rated IP4X.
Insulation Gas Options
Standard Type: 100% SF6
High-performance SF6 insulation, proven reliability, easy maintenance.
Green Type: SF6 + N2 Mixed Gas
50% SF6 reduction with nitrogen mixed gas insulation; full rated performance maintained.
SF6-Free Type: Pure Nitrogen
Zero SF6 emission, pure nitrogen insulation, non-toxic arc decomposition products.
