Whole Sale DDP Diamond Dotted Insulation Paper for Transformer and Motor

Diamond Dotted Insulation Paper (DDP) is produced of electrical insulation paper coated with warmth curable epoxy resin, the epoxy adhesive is applied to each sides of the paper in a diamond sample consisting of 9.5mm X 9.5mm diamonds with 15.9mm centre spacing.

The epoxy resin employed in DDP is dry and no conglutination at normal temperature (under 35°C). When the temperature is rising up to ninety degree C, the resin commences a single-off thaw and then one particular-off solidification. When to preserve the temperature at 90°C for ninety minutes, the epoxy resin would paste on neighboring cable and paper securely. The felt intensity is as substantial as to 70psl at 100°C.

House:
This solution has great dielectric homes and great machenical houses after getting heat-solidification. 

Application
It can be employed as coils and in between layers of oil immerged energy and distribution transformers.
