GIS Medium Voltage Switchgears
Introduction to GIS Medium Voltage Switchgears
Advanced technology for compact design, high safety, and extended equipment lifespan
GIS (Gas Insulated Switchgears) represent one of the most advanced solutions for medium voltage power distribution. Instead of air, they use SF6 gas insulation, resulting in compact dimensions, enhanced safety, and reliable performance.
At Iran Transfo Substation Development Co., we design and manufacture GIS switchgears based on modern global standards, tailored for industrial, power plant, and urban utility applications. Thanks to their long service life, environmental resistance, and fully enclosed design, they are ideal for projects where space optimization and high reliability are essential.

FAQ
- What is a GIS switchgear and how does it work?
- GIS (Gas Insulated Switchgear) uses SF6 gas to insulate internal components, enabling compact design, high operational safety, and minimal maintenance.
- What are the key advantages of GIS over traditional AIS panels?
- GIS panels are more compact, better protected against environmental factors, offer higher reliability, and require less maintenance compared to AIS (Air Insulated Switchgear).
- Is SF6 gas safe for use in electrical systems?
- SF6 is a non-toxic, effective insulating gas. While it has a high global warming potential, GIS systems are fully sealed and designed to minimize environmental impact.
- Where is GIS switchgear typically installed?
- GIS is ideal for space-constrained environments such as city substations, power plants, hospitals, and underground facilities where safety and reliability are critical.
- Can Iran Transfo Substations Development Co. customize GIS switchgear?
- Yes, all GIS solutions are tailored to client specifications, including current ratings, dimensions, and protection schemes, ensuring compatibility with various project needs.
