The product is three- phase common tank structure. The circuit breaker, disconnector, earthing switch, current transformer, voltage transformer, lightning arrester, busbars, incoming and outgoing bushings and cable terminal are fully enclosed integrated combination. So it saves more land，and is high in reliability, short in installation period, less in sealing surface, and small workload in operation and maintenance.
(1) Aluminum alloy enclosure, anti-corrosive, light weight.
(2) Equipped with a spring operating mechanism, self-energy arc-extinguishing and excellent breaking.
(3) Modular design is suitable for various design arrangements and shortens the design and construction period.
(4) When delivery, the whole bay is transported to site for the convenience of fast installation.
(5) Flexible and convenient combination, the combination of different schemes can be carried out upon users’ requests.
(6) Electronic transformers can be installed to realize digitization and intelligentization of metering and protection at power plants, and improve the automation level of power system.
(7) Realize SF6 gas pressure on-line monitoring and partial discharge live monitoring, so safety is higher.
(8) Fully enclosed gas-insulated switchgear, less or free maintenance.
