Q:What is DDM used for?

DDM is mainly used for interlayer insulation and turn insulation of transformers and voltage transformers.

Q:What is the advantage of diamond dotted coating?

The diamond dotted resin structure improves air removal and liquid infiltration between insulation layers, reducing corona and partial discharge damage.

Q:What thickness can you supply?

0.05mm, 0.07mm, 0.075mm and 0.10mm.

Q:What is the breakdown voltage?

The breakdown voltage is equal or greater than 7kV.
