Product description
The Diamond dotted Paper 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¡ æ ), The Diamond Dotted Paper (DDP)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¡ æ , The Diamond Pattern Paper (DDP)begins one-off thaw and then one-off solidification. When to keep the temperature at 90¡ æ 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¡ æ . (The value at least is equal to 0.450Mpa) (IEC standard).
