Diamond Dotted Polyester FilmDescription: 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,Website:http://www.haotai-insulation.com, 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.Features:? Thermal class: �B(130?)
