Diamond pattern insulating paper
Interlayer insulating paper for transformer winding
 |
Insulating paper with diamond shaped insulating resin application.
For interlayer insulation of transformer winding
Surface applied epoxy insulating resin hardens every layer of winding thoroughly by heat. |
| |
Applicaton example |
Excellent in insulating property
Insulating resin is excellent in resistance property against moisture, heat or oil ,
Excellent in adhesive property
Adhension at low teperature and pressure can be performed
Therefore heat deterioration of covered coil wire can be prevented.
Especially high density heat resistant paper base material can keep high adhesiveness even in 140℃ insulating-oil.
Excellent in storage stability
After one year storage at normal temperature and humidity, sufficient adhesiveness can be kept.
