Advantages of medium voltage outdoor ring main unit switchgear:

medium voltage outdoor ring main unit switchgear There are two insulation methods: one uses air insulation, and the other uses compressed gas insulation. The former has existed for a long time and is commonly referred to as switch devices. The latter is commonly referred to as gas insulated switchgear.

Gas insulated switchgear, commonly known as GIS, requires the sealing of high-voltage components (such as circuit breakers, isolating switches, load switches, grounding switches, transformers, busbars, etc.) within a closed metal enclosure filled with low-pressure compressed gas (such as compressed air, SF6, N2, etc.). Now we mainly discuss medium voltage SF6 gas insulated switchgear, hereinafter referred to as GIS.

Compared with traditional air insulated switchgear, GIS has many advantages:

1.The use of high-performance compressed gas significantly improves insulation performance, with gas insulation being 2 to 3 times better than air insulation. This advantage helps to design smaller shell sizes and improve compactness.

2.Using high-performance compressed gas can sometimes improve arc extinguishing performance.

3.Due to its sealed design, GIS is not affected by external environmental factors such as condensation, pollution, small animals, and chemicals, making it suitable for harsh environments.

4.GIS adopts a maintenance free product structure, greatly reducing maintenance work and related costs.
