SF6 tank arrester for 110-220kv system GIS

Purpose:

SF6 tank (single-phase) gapless metal oxide arrester for miniaturized GIS (hereinafter referred to as lightning arrester) is an important protective electrical appliance used to protect fully enclosed combined electrical appliances in the power system from damage from the atmosphere and operating overvoltages.

Main structural principle: This product is a gapless metal oxide arrester, which is mainly composed of a core, a disc insulator, a tank, etc., and an arrester monitor is attached. The core is encapsulated in the tank, and the tank is filled with SF6 gas with high insulation strength, which greatly reduces the insulation distance between phases and ground, reduces the footprint, and achieves miniaturization, and the product itself is not affected by the external environment , To ensure the stability and reliability of product performance.
