Introduction: Powering Modern Infrastructure Efficiently

As cities grow denser and energy demands rise, the need for compact, safe, and reliable electrical systems becomes critical. Traditional air-insulated systems often require large spaces and frequent maintenance. That’s where Gas Insulated Switchgear (GIS) emerges as a game changer — compact, sealed, and exceptionally reliable.

At Degatech Electric Co. Ltd, we specialize in engineering advanced GIS solutions that redefine how electricity is transmitted and controlled. Visit us at https://chinadegatech.com/ to explore our full range of electrical equipment.

What is Gas Insulated Switchgear (GIS)?

A Gas Insulated Switchgear is a type of metal-enclosed switchgear that uses sulfur hexafluoride (SF₆) gas as an insulating medium. This setup minimizes the size of the switchgear while providing enhanced safety and performance.

Unlike traditional systems, GIS components—circuit breakers, disconnectors, busbars—are housed in sealed metal enclosures filled with SF₆ gas, protecting them from dust, humidity, and pollution.

Key Advantages of GIS

1. Compact Design
GIS is ideal for urban or space-limited environments. A GIS system can occupy up to 10 times less space than conventional air-insulated switchgear.

2. Enhanced Safety
The sealed system eliminates exposure to environmental hazards. SF₆ gas provides superior insulation and arc-quenching capabilities, reducing fire risk.

3. Low Maintenance
Because all live parts are sealed within the enclosure, GIS requires minimal periodic inspection, leading to lower operational costs.

4. High Reliability
GIS systems maintain performance even in extreme weather—rain, salt mist, pollution, or high humidity—making them ideal for coastal or industrial regions.

Applications of GIS

• Urban Substations: Compact structure suits underground or rooftop installations.

• Renewable Energy Plants: Ensures reliability for solar and wind integration.

• Industrial Facilities: Provides uninterrupted operation in critical manufacturing zones.

• Transport Hubs: Used in airports, metros, and railway power systems.
