- Product Description
-
SMS-SIS solid cabinet is a new type of switchgear developed by our company on the basis of extensively absorbing the advantages of similar products at home and abroad.
1) Completely rule out the dependence on SF6 gas, which is a completely environmentally friendly product.
2) Vacuum arc extinguishing is used, which determines the safety and stability of its operation.
3) All the live parts are sealed, using solid-sealed pole technology, and the protection grade is IP67.
4) Phase-to-phase isolation design, the fault is limited to the faulty component itself, and the fault does not spread.
5) Suitable for low temperature and cold and highland areas.
6) The working position of the isolating switch has a special lighting and a see-through window, which can directly see the position of the isolating blade contact.
7) Modular, unitized, and generalized assembly structure, which facilitates the change of the loop expansion unit exchange program.
8) It has a variety of mechanical interlocking functions to achieve five-proof requirements.
