Diamond dotted Insulation Paper

Diamond dotted Insulation Paper is made of electrical grade Insulating paper coated with B-stage heat curable epoxy resin on either or both sides. The base paper is made from unbleached 100% Sulfate kraft pulp. The epoxy resin is applied on base paper in diamond pattern, which is consisted of 9.5mm x 9.5mm diamonds with 15.9mm center spacing. It is used in Oil-immersed Transformers for insulation between coils. At high temperature, the dotted epoxy resin melts and paste on neighboring coils to make the electrical conductor as a hard unit.
