Product Description

Diamond dotted paper made of kraft 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×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 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 (below30°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°c, the diamond dotted paper appears one-off thaw and then one-off solidification. when to keep the temperature at 90°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°c (the value at least is equal to 0.275mpa, america standard).
