Diamond Dotted Paper

Description of Diamond Dotted Paper

Diamond dotted paper is one of insulating materials, which is made of electrical Kraft paper coated on one side or both sides with modified special epoxy resin in diamond-shaped form. It has higher electrical strength and mechanical property.

Diamond Dotted Paper Product Features:

– DDP width is generally 60mm-1200mm
– Regular thickness: 0.08/0.13/0.18/0.25mm
– Color: grayish white, yellow earth
– Regular Weight: 45~60Kg per roll
– insulation class A according to IEC 641
– kraft paper, 100% sulphate pulp
– high purity and mechnical strength
– baked enamel coating: epoxy resin, rhombic, one or both side
– good compatibility with liquid dielectic after the baked enamel coating has hardened

Diamond Dotted Paper Technical Parameter

Diamond Dotted Paper Application

It is widely used in layer-to-layer insulation and turn-to-turn insulation for oil-immersed power transformer, as well as shielding isolating layer of cables, and anti-corona material for high voltage motors and electrical equipment.

When used, the coating layer begins to melt at a certain temperature during the drying process, causing adhesion, and begins to solidify as the temperature rises.

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 the layers of the winding during the short circuit, thereby ensuring the electrical and mechanical properties of the insulating structure.

Since the resin coating of the rhombic dispensing paper is spotted, the immersion of the oil and the discharge of gas in the insulating material are ensured, and the corona and partial discharge are effectively avoided, thereby ensuring the safety and reliability of the insulating structure.

It can also be used as a cable shielding isolation layer and an anti-corona material for high-voltage motors and electrical appliances.
