Polyester Film with Paperboard 6521

 Polyester Film with Paperboard 6521

It represents the two-layer composition consisting of an electrocardboard, pasted over by a polyester film on the one hand. It is applied to grooving isolation, a cover-wedge of electric machines of low power in system of isolation of a class thermal-life Е (120°С). A resource of work of 20000 hours.

The material represents the three-layer composition consisting of an electrocardboard, pasted over with two parties a polyester film. It is applied to grooving isolation, a cover-wedge of electric machines of low power in system of isolation of a class thermal-life In (130°С). A resource of work of 20 000 hours.
