Detail
Advantages of DDP insulation paper
1. It has good insulation. When in use, the coating begins to melt at a certain temperature during the drying process of the coil, producing an adhesion effect to protect the coil insulation
2. It has aging resistance and a longer service life than ordinary cable paper, between 5-10 years
Note:
Product classification:
1. According to thickness classification, we provide 0.08mm-0.13mm thickness
2. According to the color of glue dots: different color pastes, dark and light colors
3. According to the size of the diamond grid: regular 8*8, 9*9 size
All the above types can be customized
Typical applications of DDP: DDP is wound with copper foil to protect the coil
