Diamond Patten Resin Coated Paper
1. COMPOSITION AND PRESENTATION
Diamond dotted insulation paper is made of electrical insulating paper with diamond-shape epoxy resin dotted in both sides. The epoxy used in D.D.P contains a kind of incubative hardener material. It is a dry and crisp material at normal temperature(below 35℃)
Reel’s diameter: 300mm-360mm
Inside diameter of reel’s core: 76+2mm
2. PROPERTIES & APPLICATIONS
This product has good dielectric properties and good mechanical properties after heat solidification. It can used as insulation material for coils and between layers of oil immerged power distribution transformers.
