DEscriptION Diamond dotted insulation paper is made of electrical insulating papercoated with heat curable epoxy resin;the epoxy resin is applied to both sides of the paper in a diamond pattern. It is a kind of material with inertia, dry and no conglutination at normaltemperature (below 30 degree C). The Diamond Dotted Paper will make the electric conductor forever felt upas a hard unit under the high temperature by its internal latency substance. 2. FEATURESThermalclass A (105 °C) according to according to IEC 641Kraft paper, 100% sulphate pulpHigh purity and mechanical strengthGood compatibility with liquid after the baked enamel coating harden3. APPLICATIonSIt is insulation between of coils in oil-immersed transformers. 4.
