Diamond Dotted Polyester Film
Description: DDP adhesive specialty polyester film is modified epoxy resin showed DDP -shaped insulating coating on electrical baked polyester film into a stage of semi-curing the insulation material. As the diamond on a plastic resin coated polyester film is not the whole point of it was like, no coating is very conducive to the passage of air between the insulating material exclusion and liquid immersion, so that partial discharge corona damage and to minimize the damage value.
Advantage: It has excellent electrical, mechanical, and impregnating properties, no deformation after thermosetting. It also has excellent tensile strength, reliable heat resistance and good voltage characteristic.
Application: Be in gas or oil insulation system for insulation layer. It is mainly used for sulfur hexafluoride transformer and the transformer layer insulation and turn insulation.
