Product Description

DDP Diamond Dotted Resin Paper
 
 
Description:
Diamond dotted paper(DDP) is made of insulating paper with diamond-shape epoxy resin dotted on 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.
 
Features:
This product has good dielectric properties and good mechanical properties after heat solidification
 Applications:
It is to be used in oil-immersed transformers for the insulation between of coils and between layers of oil immerged power distribution transformers.

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.
