  Different uses, Zhongzhigui is commonly known as KYN28 cabinet, handcart type high voltage switchgear, generally used to protect back-end Transformers, or other high pressure load. The ring net cabinet is mainly used for the distribution of high voltage power supply. The cabinet is mainly used for high pressure load protection. Ring net cabinet with air insulation, and a fully closed filling cabinet? In both cases, the air insulation is connected to a system using a common SF6 load switch through a copper row, while a fully closed filling tank has a special connection device in addition to the power inlet and outlet line, and the cabinet is connected to the cabinet in a complete gas chamber filled with SF6 gases.
