Description

With the rapid development of modern electrical equipment, industries such as motors, compressors, electronics, and energy systems require winding materials that can maintain stable performance under increasingly demanding operating conditions.

Traditional enameled wires may experience performance limitations when exposed to high temperatures, humidity, radiation, solvents, or chemical environments. To address these challenges, Q (ZY-XY) 200/220 PEI/PAI enameled copper and aluminum round wire provides an advanced insulation solution designed for high-performance electrical applications.

Combining excellent thermal resistance, strong mechanical properties, and reliable chemical stability, this type of enameled wire has become an important material choice for high-temperature motors and electrical winding systems.

The Growing Demand for High-Temperature Enameled Wire

Electrical equipment continues to become more compact, powerful, and efficient. As a result, internal components such as winding wires are exposed to higher thermal loads and more complex operating environments.

A high-quality enameled wire must provide:

• Stable electrical insulation

• Excellent heat resistance

• Strong mechanical durability

• Resistance to chemicals and solvents

• Long-term operational reliability

The Q (ZY-XY) 200/220 PEI/PAI enameled wire is specifically developed to meet these requirements, making it suitable for applications where standard insulation materials may not provide sufficient protection.

Advanced PEI/PAI Insulation Structure

The performance of enameled wire largely depends on the quality of its insulation coating.

The PEI/PAI insulation system combines the advantages of two high-performance materials:

PEI (Polyetherimide)

PEI provides:

• Excellent thermal stability

• Strong mechanical strength

• Good electrical insulation performance

• Resistance to environmental stress

PAI (Polyamide-Imide)

PAI contributes:

• Superior heat resistance

• Excellent abrasion resistance

• Improved flexibility

• Strong resistance to chemical exposure

The combination of PEI and PAI creates an insulation layer capable of maintaining reliability under harsh working conditions.

Excellent Temperature Resistance Up to 220℃

One of the most important features of Q (ZY-XY) 200/220 enameled wire is its high temperature performance.

The product supports temperature classes of:

• 200℃

• 220℃

This allows it to operate reliably in environments where continuous heat exposure is expected.

High-temperature resistance helps:

• Extend motor service life

• Reduce insulation aging

• Improve equipment reliability

• Support higher power density designs

For manufacturers developing high-performance motors and electrical systems, thermal stability is a critical factor in material selection.

Strong Mechanical Properties for Long-Term Reliability

During manufacturing and operation, winding wires experience mechanical stress caused by bending, winding processes, vibration, and thermal expansion.

The PEI/PAI coating provides excellent mechanical performance, helping the wire maintain insulation integrity during:

• High-speed winding

• Assembly processes

• Continuous vibration operation

• Thermal cycling

This makes the wire suitable for demanding applications where insulation damage could lead to equipment failure.

Resistance to Radiation, Solvents, and Special Refrigerants

Industrial electrical equipment often operates in environments containing chemical substances or special operating conditions.

Q (ZY-XY) 200/220 PEI/PAI enameled wire provides strong resistance against:

• Radiation exposure

• Organic solvents

• Refrigerant environments

• Chemical influences

This advantage makes it especially suitable for refrigeration compressors and specialized electrical equipment operating under challenging conditions.
