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
