Diamond Dotted Paper DDP is made of insulation paper with diamond-shape special epoxy resin dotted in both sides. It is a kind of material with inertia, dry and no conglutination at normal temperature (below 35℃). It will melt when temperature is high and then will cure by latent curing agent when temperature is higher. It can make electric conductor felt up as a hard unit The special epoxy resin will bond neighboring cable and paper fast. The bonded strength is high enough to avoid coil displacement of winding in short circuit. The diamond-shape epoxy resin can guarantee oil immersed and gas given off to avoid corona discharge.
It is widely used for turn insulation in oil-immersed transformers and layer insulation in distribution transformers.
