Electrical Insulated Diamond Dotted Paper Ddp For Transformer Produced By Ztelec Group - China

Diamond dotted paper DDP is widely used in interlayer insulation and tantalum insulation of oil-immersed power transformers.

In use, the coating layer begins to melt at a certain temperature during the drying of the coil, resulting in adhesion.

Curing begins again as the temperature rises, allowing adjacent layers of the winding to be reliably bonded into a fixed unit.

The adhesive strength of the epoxy resin is sufficient to prevent the displacement of the layers of the winding during the short circuit, thereby ensuring the long-term mechanical and electrical properties of the insulation structure.

Electrical insulating paper and paperboard have certain physical performance requirements such as thickness, tightness, strength, elongation and tear.

As insulating paper, there are additional characteristics, such as electrical insulation strength, power frequency or DC breakdown voltage, dielectric loss and so on.

There are also chemical requirements such as ash, water extract conductivity and metal ions.

Electrical insulation paper for different purposes has its own special requirements.
