RIF (Resin Impregnated Fiberglass) Dry type Porcelain Wall bushing adopts the porcelain meets the IEC 62155.

RIF (Resin Impregnated Fiberglass) composite wall bushing is a new product recent years, but it has good performance in running. So it becomes popular.



RIF porcelain wall bushing advantages:

1.Certification:ISO9001, ISO14001, OHSAS18001 

2.Voltage range: from 1kV to 1100 kV,

3.Current range: from 1A to 4000A

4.Type test report

5.Large insulation margin for the design, semiconductor capacitance screen, with raise discharge inception voltage to the maximum extent, with no partial discharge in operation

6.Heat resisting and fire-retardant insulating material, with no decomposition, stable electric property, and no danger of combustion or explosion

7.Short processing cycle, customized according to customer requirements

8.Long service life, low running cost
