The Oil Transformer DDP is insulating material on the two sides of electrical insulating paper coated with rhombohedral modified epoxy resin. The epoxy resin of this material contains latent curing agent, and it is non adhesion dry material at room temperature (below 35℃). The material has excellent mechanical properties and good dielectric properties after thermal curing.

Application: it is applicable to turn insulation of coil conductor of oil immersed power transformer and interlayer insulation of distribution transformer coil.

Product characteristics: the Diamond Dotted insulation paper has a rhombus shape, which ensures the oil immersion and the discharge of the gas in the insulating material, effectively avoids the corona and the local discharge, thus ensuring the safety and reliability of the insulation.
