Characteristics of Chalco polyester enamelled aluminium round wire
Advantages
- Excellent voltage breakdown resistance in dry and humid conditions
- Excellent softening breakdown performance
- Good overload resistance
- QZX type enamelled wire reduces the coefficient of friction on the surface of the enamel film and improves the elasticity and scratch resistance of the enamel film, making it suitable for automated high-speed winding and mechanical insertion.
Limitations
- Poor hydrolysis resistance (for use in closed motors and electrical appliances)
- Poor thermal shock resistance and poor elasticity of the lacquer film
- Incompatible with high chlorine content compounds such as PVC and neoprene
- Incompatible with polystyrene
- Easily corroded by strong acids
- 130L polyester enameled wire is banned in Europe and America
- Class 130 and 155 polyester enamelled aluminium wire is not suitable for use in high efficiency motors
