33kV Isolator / Disconnector

33kV isolator/disconnector is mainly applied in AC10~40.5kV, 50Hz power system. 33kV isolator/disconnector is widely used in electric power, railway, mining and oil field. And all fittings not only reasonably& integrally designed but also made of high quality materials

1. Stainless steel disc spring bowl- It makes two contact parts much more tighten, and supplies very low resistance.



2. Operation pull ring--- The lever design of pull ring and shift lock-pin ensures high breaking ability.



3. Contact methods---using surface contact instead of point contact, the device prevents too large resistance leading to heat too fast, and provides fire protection as well.
