Electrical Insulation Diamond Dotted Polyester Film
Electrical insulation resin with diamond-shaped single-sided or double-sided coating on polyester film, then baked to form a semi-curing stage diamond glue film. It’s mainly used for instrument transformer, transformer insulation between the layers and turn to turn insulation.
Diamond pattern resin coated polyester film is a kind of insulation material which spread a special kind of change-quality insulation epoxy resin on the electrical-grade polyester film and the shape of resin coat like diamond pattern.
The film exhibits long-term insulated structural, good electrical mechanical properties, no deformation after thermosetting.
Diamond pattern resin coated polyester film has already been widely used in electrical equipments such as mutual inductance machine, transformer and etc. It is also widely used in the gas or oil insulation system as layers insulation.
