Product Description

Product Description

 

NOMEX Paper Covered Copper or Aluminum Flat Wire

Nomex Paper Covered Magnet Wire is the winding wire and its conductor is made of oxygen-free copper rod or electrical round aluminum rod ,through a certain specification of the extrusion mould or after drawing wire and annealing treatment,and then the copper (aluminum) conductor is wrapped on two or more than two layers of insulating paper (including telephone paper, cable paper, high voltage cable paper, turn-to-turn insulation paper).



Nomex Paper is one kinds of a paper insulation for magnet wire the standard thermal class is 220° C. Nomex Paper Covered Magnet Wire may be impregnated with oil, chlorinated bi-phenyl, or silicone. Nomex paper has excellent tear resistance and is resistant to damage during winding.

Application

 

 

Paper-insulated wire, also known as paper-covered wire, is widely used in electrical and industrial fields due to its unique insulation properties and durability. Key applications include:

1. Transformers: Paper-insulated wire is commonly employed in transformer windings. Its layered paper insulation provides excellent dielectric strength, making it suitable for high-voltage applications.

2. Electric Motors: In motors requiring high thermal resistance, paper-insulated windings help prevent short circuits and enhance operational stability.

3. Inductors and Coils: The wire's insulation stability at elevated temperatures makes it ideal for inductors in power electronics and telecommunications equipment.

4. Vintage Electrical Systems: Older industrial machinery or restoration projects often use paper-insulated wires to maintain authenticity and compatibility.

5. High-Temperature Environments: Its resistance to thermal degradation allows use in applications like furnace wiring or heavy-duty industrial equipment.

6. Power Distribution: Historically, paper-insulated cables were used in underground power distribution systems due to moisture resistance and mechanical robustness.
