Product Description

Brief Introduction
Diamond dotted insulation paper is made of electrical insulating paper coated with heat curable epoxy resin on one or both sides. It will make the electric conductor forever felt up as a hard unit under the high temperature by it
internal latency substance when the temperature is rising up to 90 degree c. lt is to beused in oil-immersed transformers for the insulation between coils.
