Protection level: IP67, can be fully immersed in water for a long time.

Environmental Protection: Free from SF6 greenhouse gas, it is an environmentally friendly product.

Swap design: e upper and lower isolation schemes have identical switch shapes and installation dimensions, and can be combined arbitrarily to achieve universal upper and lower isolation in the same substation.

Independent switch: e rota isolation switch and grounding switch are set independently, eliminating the defect of the main circuit being aected by blade burnout when the three position switch is grounded and closed.

Phase to phase independence: Each phase has an independent structure to avoid phase to phase sho circuits and achieve modular assembly and replacement.

Compament independence: e switch includes an isolation switch, a vacuum arc extinguishing chamber, a grounding switch, and three pas with their own independent sealed paitions.

Creep distance design: e 202 European style connector for the outgoing line adopts an increased creepage distance design, which avoids the creepage phenomenon caused by improper installation of the European style cable connector or silicone grease hardening.

Full visibility: ere are 6 obseation pos, LED lights inside the switch, three-phase isolation switch, and any position of the grounding switch is visible.

Operating mechanism: Equipped with a spring operating mechanism, it can be operated manually or electrically. e isolation switch, vacuum arc extinguishing chamber, and grounding switch inside the switch are operated independently and interlocked with each other, meeting the ve prevention interlocking requirements.

Anti pollution: e product is a fully insulated, fully sealed, maintenance free structure with no exposed live pas and is not aected by external pollutants.

Expansion design: e product design dimensions have been considered to be compatible with the 1250Acontainer that will be developed later.
