The high-voltage porcelain wall bushing is composed of a porcelain sleeve, a conductor, an intermediate flange and end accessories. The porcelain sleeve is the main insulation of the bushing, the intermediate flange is normally grounded, and the conductor normally passes high-voltage current.

It is recommended to use products with a creepage ratio of 2.5cm/kV and 3.1cm/kV, which not only have high pollution resistance at the outdoor end, but also increase the creepage distance at the indoor end as much as possible to prevent flashover caused by condensation and other reasons.

According to the standard

·IEC 60137, GB/T 4109

The main technical parameters

·Ambient temperature: -50℃~+50℃

·Rated voltage: 12kV-40.5kV

·Rated current: 630A - 6O0O

·A Other parameters are in accordance with the standard.
