Product Details
expoxy resin Electric transformer Insulation Diamond Dotted Paper (DDP)
Kraft paper is abailable with both sides of diamond dotted pattern expoxy resin, which is cnsisted of 9.5mm x 9.5mm diamonds with 15.9mm center spacing.
It is to be used in oil-immersed transformers for the insulation between the coils. The dotted epoxy resin melts at high temperature.Diamond dotted electrical materials insulating paper.is produced by coating modified epoxy-resin in diamond-dotted patterns on electrical insulating paper.This design improves the mechanical strength of oil-immersed transformer winding without reducing partial discharge levels. It is suitable for turn-to -turn insulation of coil wires on oil-immersed power transformers and suitable for layer insulation of coils on distribution transformers.
The Diamond Dotted Paper will make the electric conductor forever felt up as a hard unit under the high temperature by its internal latency substance. when the temperature is rising up to 90 degree C. The Diamond Paper begins one-off thaw and then one-off solidification .When to keep the temperature at 90 degree C for 90 minutes, the epoxy resin would paste on neighboring cable and paper safely. The felt intensity is as high as to 70psi at 100 degree C (The value at least is equal to 0.275Mpa, America standard).
