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 used in oil-immersed transformers for the insulation between of coils.
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).
