The problem of existing creepage distance shortens, effectively improves insulation performance of the resistance unit in rain spraying environment, meet resistance unit
High pressure resistant requirement in rain spraying environment.
By using integral insulation pipe, completely eliminate between original porcelain piece and resistance band and between porcelain piece and porcelain piece
Gap so that being not in since rain spraying environment makes between porcelain piece and resistance band and porcelain between resistance band and support rod
Gap infiltration between part and porcelain piece, leads to conduction, so that the creepage distance between resistance band and support rod is substantially reduced
The phenomenon that occur, test proves that the pressure-resistant performance using integral insulation pipe will not be influenced by rain spraying environment again, Er Qienai
Pressure performance has large increase, is as follows: with traditional porcelain piece isolation method contrast test effect
| Serial number | Title | Pressure voltage under drying condition | Pressure voltage under the conditions of drenching with rain |
| 1 | Insulate pipe unit | 20000 VAC | 7000 VAC |
| 2 | Conventional elements | 12000 VAC | 3000 VAC |
By above-mentioned test result it is clear that improved pressure resistance performance is improved significantly, height can satisfy completely
The performance requirement of the various environment such as iron, motor-car.
