AC Outdoor High Voltage 33kV Isolator

AC outdoor high voltage 33 isolator is mainly applied in AC10~40.5kV, 50Hz power system. The ac outdoor high voltage 33kV isolator is widely used in electric power, railway, mining and oil field. And all fittings of the ac outdoor high voltage 33kV isolator 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.
