Brief Introduction of Diamond Dotted Insulation Paper
Diamond pattern paper made of Kraft paper coated with heat curable epoxy resin.The epoxy adhesive is applied to both sidesof the paper in a diamond pattern consisting of 9.5mm x9.5mm diamonds with 15.9mm center spacing.
The Diamond Dotted Paper (DDP) will make the electric condctor forever felt up as a hard unit under the high temperature by its internal latency substance. When the temperature is rising up to 90℃, The Diamond Pattern Paper (DDP)begins one-off thaw and then one-off solidification. When to keep the temperature at 90℃ for 90 minutes, the epoxy resin would paste on neighboring cable and paper safely. The felt intensity is as high as to 70 psl at 100℃.(The value at least is equal to 0.450Mpa) (IEC standard)
Application:
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℃).
