Air Insulated ring cabinet, ordinary called semi-insulated ring cabinet, air insulated ring cabinet commonly known asFully Insulated ring mesh cabinets, The difference is:
1, the distance between the inflatable and the insulating cabinet is only 1/3 of the air insulation cabinet, the size of the switchgear greatly reduced.
2, all fully insulated ring cabinet insulation Media: The use of sf6, n2 and other gases or its composite gas as an insulating medium, insulation function is strong.
3, Electrical clearance: Insulation gas insulation function is far better than air, the electrical clearance of the fully insulated ring cabinet cabinet is much smaller than the semi-insulated cabinet.
4, Equipment size: Due to small electrical clearance, full insulation cabinets than the same class semi-insulated cabinets much smaller, accounting for small air accumulation.
5, High Impact: The main circuit element of the fully insulated ring cabinet is placed in the inflatable compartment, the pressure is constant. They are not affected by altitude. Semi-insulated ring cabinet insulation function is directly affected by the height. Standard products are used below 1000m, with a high degree of high demand for special design.
6, pollution effect: pollution will not affect the fully insulated ring cabinet inflatable compartment, suitable for contaminated areas. Semi-insulated ring cabinets are directly affected by contamination.
