Product Description

These enameled resistance wires have been broadly used for standard resistors, automobile
parts, winding resistors, etc. using the insulation processing best suited for these applications, taking full advantage of the distinctive features of enamel coating.

Furthermore, we will carry out enamel coating insulation of precious metal wire such as silver and platinum wire upon order. Please make use of this production-on-order.

Tpye of Insulation:

1) Polyester resistance wire , class 130

2) Modified polyester resistance wire , class 155

3) Polyesterimide resistance wire , class 180

4) Polyester (imide) coated with polyamide-imide resistance wire , class 200

5) Polyimide resistance wire , class 220
