The description of DDP

The DDP is coated with special modified epoxy resin in the shape of diamond on high-performance insulating paper which is widely used in the interlayer insulation and turn insulation of oil-immersed power transformers. In use, the coating layer begins to melt at a certain temperature during the drying process of the coil, resulting in adhesion. As the temperature rises, it begins to solidify, so that the adjacent layers of the winding are reliably bonded into a fixed unit. The adhesive strength of the epoxy resin is sufficient to prevent the displacement of the winding layers during short circuit, thereby ensuring the long-term mechanical and electrical performance of the insulating structure.

Because the resin coating of DDP is dot-shaped, it ensures the immersion of oil and the discharge of gas in the insulating material which effectively avoiding corona and partial discharge, thus ensuring the safety and reliability of the insulating structure.

The applications and features of DDP

DDP is an insulating material with special modified epoxy resin in a diamond shape on electrical insulating paper. DDP are widely used in the interlayer insulation and interturn insulation of oil-immersed power transformers. When used, the coating layer starts to melt at a certain temperature during the drying process of the coil, causing adhesion and then solidifies as the temperature increases so that the adjacent layers of the winding are reliably bonded into a fixed unit. The adhesive strength of the epoxy resin is sufficient to prevent the displacement of the winding layers during short circuit, thereby ensuring the long electrical and mechanical properties of the insulating structure.

Because the resin coating of DDP is dot-shaped, it ensures the immersion of oil and the discharge of gas in the insulating material that effectively avoiding corona and partial discharge, thereby ensuring the safety and reliability of the insulating structure. It can also be used as cable shielding isolation layer and anti-corona material for high-voltage motors and electrical appliances.

DDP insulation paper is an insulation material coated with special modified epoxy resin in the shape of diamond on electrical insulation paper. The epoxy resin of this material contains a latent curing agent. At room temperature (below 35 ° C) that is a dry material that does not block. When heated to a certain temperature, it begins to melt and produce adhesion. As the temperature rises, it begins to solidify, so that the adjacent layers of the winding are reliably bonded into a fixed unit. The adhesive strength of the epoxy resin is sufficient to prevent the displacement of the winding layers during short circuit, thereby ensuring the long-term mechanical and electrical performance of the insulating structure. Because the resin coating of DDP is dot-shaped which ensures the immersion of oil and the discharge of gas in the insulating material that effectively avoiding corona and partial discharge, thus ensuring the safety and reliability of the insulating structure. It is suitable for the turn insulation of coil wires of oil-immersed power transformers and the interlayer insulation of coils of distribution transformers.
