Product Description

Product Info High Voltage GIS Gas Insulated Switchgear

(72.5kV / 110kV / 145kV / 220kV / 252kV GIS Substation)

252kv Customized Gis Switchgear Installation

Our GIS Gas Insulated Switchgear is a compact, fully enclosed high-voltage switchgear system using SF6 gas as the insulating and arc-quenching medium.

It is designed for reliable operation in urban substations, industrial plants, power utilities, renewable energy projects, and harsh environments where space saving and high safety are required.

The system integrates circuit breaker, disconnector, earthing switch, busbar, and instrument transformers into a sealed metal enclosure, ensuring high reliability, long service life, and minimal maintenance.

Key Features

Compact design, saving up to 70% substation space
Fully sealed structure, dust-proof, moisture-proof, corrosion-resistant
High operational safety and long maintenance intervals
Modular design, flexible for extension and customization
Stable performance in high altitude, coastal, and polluted environments
Suitable for EPC projects and turnkey substations
