AC Outdoor High Voltage 12kV Isolator Switches  

AC outdoor high voltage 12kV isolator switches are mainly applied in AC10~40.5kV, 50Hz power system. The 12kV isolator switches are widely used in electric power, railway, mining and oil field. And all fittings of the 12kV isolator switches not only reasonably& integrally designed but also made of high quality materials.

Conductive contact parts---All the parts are over 20μ silver coating, preventing from oxidation easily.

Insulator---Epoxy resin insulator provides the performances of strong environment adaptability, self-cleaning ability, ultraviolet resistance and waterproof.

Base plate---Stainless steel or hot galvanizing base ensures reliable manipulation & corrosion resistance.

1 piece 12kV isolator switches per poly bag, each product is wrapped with poly foam inside and standard carton outside.

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.

The design and test of 12kV isolator switches are complied with the following standards:
