Polyester Film Non-vowen fabric 6630

 Polyester Film Non-vowen fabric 6630

 represents the two-layer composition consisting from polyester film and a polyester paper. It is applied to grooving isolation, a cover-wedge of low-voltage electric machines in system of isolation of a class thermal-life characteristics B (130°С) . It can also to be used as interlaminar isolation in dry transformers. A resource of work of 20000 hours.

 Polyester Film Non-vowen fabric 6630 represents the three-layer composition consisting from polyester film, the polyester paper pasted over from two parties. It is applied to grooving isolation, a cover-wedge of low-voltage electric machines in system of isolation of a class thermal-life characteristics B (130°С). It can be used also as interlaminar isolation in dry transformers. A resource of work of 20000 hours.
