Product Description

Insulated Nomex Paper Covered Aluminum Magnet Wire

Nomex paper covered magnet wire is the winding wire and its conductor is made of oxygen-free electrical round aluminum rod,through a certain specification of the extrusion mould or after drawing wire and nanealing treatment, and then the aluminum conductor is wraped on two or more than two layers of insulating paper(including telephone paper, cable paper, high voltage cable, turn to turn insulation paper)
Nomex paper is one kind of a paper insulation for magnet wire
