The enamel coating serves as a durable insulating barrier while maintaining the flexibility needed for efficient winding processes.

Excellent Heat Resistance for Stable Performance

Temperature management is one of the most important factors affecting the lifespan of electrical equipment. Excessive heat can accelerate insulation aging, reduce efficiency, and increase the risk of failure.

QQ/120 enameled wire is designed to withstand continuous operating temperatures up to 120°C, making it suitable for a wide range of electrical applications where moderate thermal resistance is required.

Its thermal stability helps maintain insulation integrity during prolonged operation, contributing to more reliable equipment performance and longer service life.

High Mechanical Strength Supports Manufacturing Efficiency

Winding operations place significant mechanical stress on magnet wire. During production, wire may be subjected to tension, bending, layering, and high-speed winding processes.

QQ/120 Acetal Polymer Enameled Wire offers strong mechanical properties that help reduce damage during manufacturing.

Benefits include:

• Improved resistance to abrasion

• Reduced risk of insulation cracking

• Better handling during automated winding

• Consistent winding quality

These characteristics help manufacturers improve production efficiency while reducing material waste.

Strong Resistance to Solvents and Chemicals

Industrial electrical equipment often operates in environments where exposure to oils, cleaning agents, and chemical substances is unavoidable.

One of the notable advantages of QQ/120 wire is its strong solvent resistance. The acetal polymer insulation provides excellent protection against many industrial chemicals, helping preserve insulation performance over time.

This feature is particularly valuable for equipment operating in manufacturing facilities, power systems, and industrial processing environments.

Compatibility with Transformer Oil

Transformer reliability depends heavily on the interaction between winding materials and insulating fluids.

QQ/120 Acetal Polymer Enameled Wire is designed so that transformer oil does not adversely react with the insulation coating. This compatibility helps maintain long-term insulation stability and supports safe operation within oil-immersed transformer systems.

For transformer manufacturers, this characteristic contributes to improved durability and reduced maintenance concerns throughout the equipment lifecycle.
