Used in Oil-type transformers ,good electrical and mechanical purposes

Diamond Dotted Paper

 

Made of Kraft 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×9.5mm diamonds with 15.9mm center spacing

The Diamond Dotted Paper, alias such as: epoxy adhesive diamond Paper, Diamond Dotted Presspaper,

Double sided Diamond Pattern Paper, DDPP, DPRCP, D.D.P, DPP, Diamond Dotted Insulating Paper, Varnished Paper, etc.

It is to be used in oil-immersed transformers for the insulation between coils. On the insulation layer, there is a layer dotted epoxy resin that will be changed with high temperature change that is to be called as felt.

It is a kind of material with inertia, dry and no conglutination at normal temperature (below30°C),The Diamond Dotted Paper will make the electric conductor forever felt up as a hard unit under the high temperature by its internal latency substance. When the temperature is rising up to 90°C, The Diamond Dotted Paper appears 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 (The value at least is equal to 0.275Mpa, America standard).
