Applications 
Production: DDP is produced by coating modified epoxy-resin in diamond-dotted patterns on electrical insulating paper
Anvantages: In the process of coil desiccation, the coated epoxy-resin would be melted in a certain temperature and become adhesive. With the temperature increased, the melted resin would cure to C-stage, and firmly adheres each adjoining layer of the coil, thus forming a winding section.If a short circuit occurs in the coil, the resin bond strength would sufficiently prevent the displacement of each winding layer, which ensures the long-term mechanical and physical properties of the insulation structure. As the resin coating distributes in a diamond-dotted pattern,little quantity of the resin would soak into the insulating paper during the melting and curing process, which ensures the elimination of air content in the insulating paper and guarantees the soakage of oil, minimizing the damages of corona and partial discharge.
Applications: 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.
