HIGH TENSION WIRE - HTW
General Description
ELEKTRISOLA high tension wire (HTW) is a copper alloy specially designed for applications with high mechanical requirements. The higher tensile strength allows for increased winding speeds and less wire breaks in coil winding. The excellent bending proof performance increases the reliability and lifespan of applications under dynamic load.
High tension magnet wire is available in diameters from 0.020mm to 0.150mm (AWG 52 - 34) with all insulation and self-bonding enamel types. ELEKTRISOLA (HTW) is also available in bare wire.
Features
- High tensile strength
- Excellent bending proof performance
- High conductivity
