145 kV Gas Insulated Switchgear (GIS)

Inkan Power proudly delivers advanced 145 kV Gas Insulated Switchgear (GIS) systems engineered for safe, reliable, and space-efficient power transmission. Designed for critical infrastructure, substations, and industrial networks, our GIS technology provides modular solutions to meet the demands of modern energy distribution.

Key Features

Compact Structure : Our 145 kV GIS boasts a three-phase common enclosure design, maximizing space savings and installation flexibility for diverse project requirements.
High Reliability: Built to reduce annual gas leakage below 0.1%, and with exceptional insulation performance, our systems guarantee whole bay partial discharge of less than 3pC. Advanced sealing and interlocking mechanisms minimize misoperation and maximize uptime.
Maximum Safety: Inspection pathways and access are strategically positioned, eliminating the need for personnel to enter the bay for routine checks, reducing risk and operational hazards.
Modular Design: Standardized flanges and interchangeable modules enable customized configurations, future expansion, and optimal layout of substations or switchgear rooms.
