Made of kraft 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 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 of 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 (below 30 degree 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 degree C, The diamond dotted paper begins one-off thaw and then one-off solidification. When to keep the temperature at 90 degree 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 degree C (The value at least is equal to 0.275Mpa, America standard)
