Durable Dotted Insulating Epoxy Paper for Transformer Windings

Product Description

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).

 

Application:
It is used in Oil-immersed Transformers for insulation between coils. The advantage with partially coated insulation press paper lies in the internal strengthening of the coil from adhesion to the conductor; this provides passage for quick evacuation of air and moisture during the drying process. It also minimizes the risk of partial discharge,quick impregnation and flow of oil through the channels. The bonding strength of the epoxy resin is sufficient to prevent displacement of winding layers due to short circuit forces.
