Class 200 Polyesterimide Enamelled Wire

 

We supply Class 200 polyesterimide overcoated with polyamide-imide enamelled wire for motors, transformers, generators and other electrical winding applications.

This enamelled wire uses a composite enamel insulation system consisting of polyesterimide and polyamide-imide resins. The listed specification combines a 200 thermal class with refrigerant resistance, solvent resistance and stable electrical insulation performance.

When you select this magnet wire, the thermal class alone is not enough. You should also confirm the conductor material, round or flat wire form, conductor dimensions, enamel build, applicable IEC or GB/T standard and the electrical or mechanical tests required by your winding design.

If your drawing specifies another standard edition, insulation grade or test method, send us the exact requirement before quotation. We can then confirm whether the enamelled wire specification matches your winding design.

 

 

The main characteristic of this product is its composite enamel coating.

The conductor is insulated with a polyesterimide / polyamide-imide enamel system designed for winding applications that require higher thermal performance together with electrical, mechanical and chemical resistance.

For purchasing, the enamel system should be checked together with:

• conductor material;
• conductor dimensions;
• round or flat wire form;
• enamel build;
• thermal class;
• electrical test requirements;
• mechanical and chemical-resistance requirements.

This is more useful than selecting enamelled wire only from the phrase "Class 200."

 

 

Motor windings are one of the main applications for polyesterimide / polyamide-imide enamelled wire.

The enamel coating provides electrical insulation between adjacent turns, while the thermal class must match the temperature conditions expected in the motor winding system.

Before ordering magnet wire for a motor, confirm:

• nominal conductor size;
• required enamel thickness;
• thermal class;
• winding method;
• required breakdown-voltage test;
• mechanical requirements during winding.

 

 

You can also evaluate this Class 200 enamelled wire for transformers, generators, inductors and solenoid coils.

In these applications, the enamel coating provides turn-to-turn insulation while the conductor carries the electrical current through the winding.

The correct wire should therefore be selected from the complete electrical design rather than only from conductor diameter.

For transformer or coil projects, send us the required conductor material, dimensions, thermal class, insulation build and applicable standard before production.

 

 

The current product is also suitable for evaluation in automotive electrical components and household electrical equipment that use insulated winding coils.

Typical applications can include ignition-coil windings, sensors, fans, air-conditioning equipment and other electromagnetic components.

Actual suitability depends on the operating temperature, voltage, winding dimensions, mechanical stress and chemical environment of the finished component.

 

 

In addition to the main Class 200 enamelled wire specification, the current product information also lists related flat enamelled wire production ranges.

Model	Enamelled Wire Type	Production Range
QYB	Class 220 Polyamide-Imide Enamelled Flat Wire	a: 0.80-5.60mm / b: 2.00-16.00mm
Q(ZY/XY)B	Class 200 Polyesterimide / Polyamide-Imide Enamelled Flat Wire	a: 0.80-5.60mm / b: 2.00-16.00mm

For round enamelled wire, send us the required conductor diameter. For flat enamelled wire, provide both a × b dimensions.

 

 

The enamelled wire specification should define the properties that must be checked before the material is accepted for winding production.

Depending on your design, the inspection scope may include:

• conductor dimensions and tolerance;
• overall wire dimensions;
• enamel build;
• electrical insulation performance;
• mechanical resistance;
• thermal performance;
• solvent resistance;
• refrigerant resistance where required.

If your incoming inspection follows a specific IEC, GB/T or internal company test method, include it in the purchase specification before production.

 

 

We confirm the enamelled wire specification before production and carry out inspection before shipment.

The main order parameters include conductor type, conductor size, enamel system, thermal class, applicable standard and the inspection values required by your winding project.

A pre-production sample can also be discussed when you need to verify winding or electrical performance before mass production.

Q1: What type of enamelled wire is this?
It is polyesterimide enamelled wire with a polyamide-imide overcoat, using a composite enamel insulation system.

Q2: What is its thermal class?
The current listed specification is Class 200.

Q3: What applications can use this magnet wire?
It can be evaluated for motors, transformers, generators, inductors, solenoids and other electrical winding applications.

Q4: What standards are listed for this enamelled wire?
The current product information lists GB/T 7095.6-2008 and IEC 60317-29:1990, with GB/T 4074 and IEC 60851 as listed testing references.

Q5: What is the difference between round and flat enamelled wire dimensions?
Round wire is normally specified by conductor diameter. Flat enamelled wire requires two conductor dimensions, usually expressed as a × b.

Q6: Is the 0.80-5.60mm × 2.00-16.00mm range for round wire?
No. The listed dimensions belong to the related flat enamelled wire production range.

Q7: Can you provide a sample before mass production?
Yes. Send us the conductor type, dimensions, enamel system, thermal class and application so we can confirm the appropriate sample.

Q8: What information do you need for an enamelled wire quotation?
Send the conductor material, round or flat wire form, dimensions, enamel build, thermal class, applicable standard, quantity and application.

 

 

 

We can confirm enamelled wire conductor type, dimensions, enamel build, thermal class, inspection requirements and export documentation according to your agreed specification.
