Product Description

Diamond Dotted Insulation Paper( DDP) is made of electrical insulation paper with Diamond-shape epoxy resin dotted in both sides. The epoxy resin used in DDP contains a kind of incubative hardener material, it is a dry ad crisp material at normal temperature(below 35degree)

This product has good dielectric properties and good machenical properties after being heat-solidification. It can be used as coils and between layers of oil immerged power and distribution transformers.
