DDP Diamond Dotted Paper
Description :
1. COMPOSITION AND PRESENTATION
Diamond pattern resin coated paper is a kind of insulation material which spread a special kind of change-quality insulation epoxy resin on the electrical-grade kraft paper and the shape of resin coated like diamond pattern. Because the shape of resin coat assumes point not covering all surface. The passages without resin are best useful to degas insulation materials and intrude liquid or gas insulation materials. It reduces the broken degree of electrical-halo or partial discharge to the lowest.
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.
