F-DMD dry type transformer interlayer insulation material
F-DMD could be used in some small dry type transformers, which is made of three layers, Dupont Darcon and Mylar non-woven material.
Description:
F-DMD dry type transformer Lamination Insulation film is a three-layer flexible composite material, produced by using F-class adhesive to adhere the two faces of high-melt-point polyester film (Mylar) with hot rolling non-woven polyester fabric (Dacron).
Advantages:
It has high performance electrical, mechanical, soft and tear resistant properties, easy to fit the interlayer insulation.
