1.Small footprint: GIS equipment encloses all electrically charged parts in a metal enclosure, dramatically reducing the footprint. For example, the footprint of a 220kV GIS is only about 15% of that of a conventional substation of the same size.

2.High operational reliability and safety: The insulating properties of GIS equipment are not affected by the surrounding atmospheric conditions, and its strong seismic resistance improves operational reliability. In addition, the electrically charged part of the equipment is enclosed in a metal casing, which avoids the pollution of the environment by high voltage and prevents people from being electrocuted and killed at the same time.

3.Long maintenance cycle: GIS equipment has a long maintenance cycle, and generally can be dismantled and overhauled within 10 to 20 years, reducing maintenance costs and downtime.

4.Strong environmental adaptability: GIS equipment is designed according to IEC international standards and is suitable for various environmental conditions, including low temperature environment.

5.Compact structure: The components of GIS equipment are compact, with a minimum spacing of 2 meters, further saving space.

6.Intelligent monitoring and diagnostic functions: Equipped with electronic equipment, transmitters and actuators, advanced GIS equipment not only has the basic functions of a switchgear, but also has additional functions, and excels in monitoring and diagnostics in particular.
