Product Description
The CHINGCUNG Q(ZY/XY)-2/200 enameled copper wire features a dual-layer insulation system. The base coat consists of modified polyesterimide resin (Class 180/200), while the outer coat is a high-performance polyamideimide (PAI) layer. This unique composite structure combines the excellent thermal properties of polyesterimide with the outstanding abrasion resistance, chemical inertness, and refrigerant compatibility of polyamideimide.
Unlike single-coated wires, this product is specifically engineered for hermetic motor applications, where prolonged exposure to refrigerants (such as R134a, R410A, R32) and lubricating oils is common. It ensures long-term reliability under extreme operating conditions.
Key Advantages & Performance Features
|
️ Superior Refrigerant Resistance
Excellent stability when exposed to HFCs (R134a, R410A, R32), HCFCs, and CFCs. Ideal for sealed compressors in AC and refrigeration systems.
|
️ Outstanding Mechanical Strength
The PAI topcoat provides exceptional abrasion resistance and surface lubricity, reducing scrap rates during high-speed automatic winding.
|
|
️ High Thermal Stability
Rated for continuous operation at 200°C with a cut-through temperature exceeding 320°C, offering a safety margin for overload conditions.
|
Excellent Dielectric Properties
High breakdown voltage and stable insulation resistance across a wide temperature range (-40°C to 220°C).
