Product Description

Diamond Dotted Insulation Paper (DDP) is made of electrical insulation paper coated with heat curable epoxy resin, the epoxy adhesive is applied to both sides of the paper in a diamond pattern consisting of 9.5mm X 9.5mm diamonds with 15.9mm center spacing.

The epoxy resin used in DDP is dry and no conglutination at normal temperature (below 35°C). When the temperature is rising up to 90 degree C, the resin begins one-off thaw and then one-off solidification. When to keep the temperature at 90°C for 90 minutes, the epoxy resin would paste on neighboring cable and paper safely. The felt intensity is as high as to 70psl at 100°C.

Property:
This product has good dielectric properties and good machenical properties after being heat-solidification. 

Application
It can be used as coils and between layers of oil immerged power and distribution transformers.
