Diamond Dotted Insulating Paper (DDP) for Transformer

Diamond Dotted Paper (DDP) is made of high-grade electrical

Insulating Papercoated with special modified epoxy resin in regular rhombic pattern. It features excellent dielectric property, mechanical strength, heat resistance and oil resistance, widely used as key insulation material for oil-immersed power transformers and large & medium-sized electric motors.When heated, the diamond-shaped adhesive dots melt to bond adjacent layers and then cure completely with rising temperature, firmly fixing transformer windings. It greatly improves the anti-short-circuit and anti-impact performance of coils. The non-glued areas ensure superior oil permeability to keep stable insulation performance. Available in various thicknesses and widths, with uniform glue distribution and smooth feeding, perfectly compatible with automatic winding machines. Ideal for turn-to-turn, interlayer and coil

end insulation of transformers.
