Motor winding D.D.P insulation paper

D.D.P---Diamond dotted insulation paper is made of electrical insulating paper with diamond-shape epoxy resin dotted in both sides. The epoxy resin used in D.D.P. contains a kind of incubative hardener material, it is a dry and crisp material at normal temperature(below 35 °C ). D.D.P Insulation paper Features and Applications: --Good dielectric properties and mechanical properties afer being heat-solidification. --As interturn insulation for coils of oil-immersed transformers interlayer insulation of distribution transformers.  D.D.P Insulation paper technical date:
