Usage It is also known as DDP. The use of this B-stage resin coated paper increases the short circuit strength of distribution transformer coils. It is produced by coating modified epoxy resin in diamond dot patterns on electrical insulating paper. The size of the dots are carefully designed to avoid interfering with vacuum drying and oil impregnation. This type of presspaper is treated chemically and included nitrogen content to get a upgraded thermo performance.
Feature Diamond dotted insulation paper has better dielectric properties and better mechanical properties than normal DDP paper after heat solidification. DDP diamond dotted insulation paper for transformer ddp insulating paper
Advantage Diamond Dotted Paper insulating paper is an insulating material which is coated with special modified epoxy resin in diamond-shaped shape on electrical insulating paper. It is widely used in interlayer insulation and turn insulation of oil-immersed power transformer. Because the resin coating of the diamond lattice adhesive insulating paper is point-like, it ensures the immersion of oil and the discharge of gas in the insulating material, effectively avoids corona and local discharge, and thus ensures the safety and reliability of the insulation structure.

Insulating Paper for Transformer Cable Impregnated Electrical Insulation Material Diamond Dotted DDP Insulation Material

Features: DIAMOND DOTTED PAPER (DIAMOND DOTTED PAPER) is commonly known as dotted paper. It is a special modified epoxy resin in the shape of diamond coating on electrical insulation paper insulation material. It is widely used in interlayer insulation and turn insulation of oil-immersed power transformer. When used, the coating layer begins to melt at a certain temperature during the coil drying process, resulting in adhesion. As the temperature rises, it begins to cure again, so that the adjacent layers of the winding are reliably bonded into a fixed unit. The bonding strength of the epoxy resin is sufficient to prevent the displacement of each layer of the winding during short circuit, thus ensuring the long-term mechanical and electrical properties of the insulation structure..

INTRODUCE:Diamond Dotted Paper is made of Kraft coated with heat curable epoxy resin, the epoxy adhesive is applied to both sides of the paper in a diamond pattern consisting of 9.5mm×9.5mm diamonds with 15.9mm center spacing.Usage: DDP is primarily used as layer and winding insulation in the LV and HV coils of transformers. After curing, the partial resin coating bonds the electric conductors with the insulation, which brings about the mechanical consolidation of the coils. In this way the radial and axial forces that arise in the event of short circuit can be safely controlled.

Usage:
Diamond pattern paper made of Kraft paper coated with heat curable epoxy resin.The epoxy adhesive is applied to both sidesof the paper in a diamond pattern consisting of 9.5mm x9.5mm diamonds with 15.9mm center spacing.,the Diamond dotted Paper is to be used in oil-immersed transformers for the insulation between of coils. On the insulation layer, there is a layer dotted epoxy resin that will be changed with high temperature change that is to be called as felt. It is a kind of material with inertia, dry and no conglutination at normal temperature (below 30ºC).
The Diamond Dotted Paper (DDP) will make the electric condctor forever felt up as a hard unit under the high temperature by its internal latency substance When the temperature is rising up to 90ºC, The Diamond Pattern Paper (DDP)begins one-off thaw and then one-off solidification.
