APET-200 (d 1.70 mm) Enameled Aluminum Winding Wire: High Thermal Resistance and Cost-Efficient Engineering by Fenitec
In modern electrical engineering and power apparatus manufacturing, balancing overall production costs while maintaining uncompromising reliability is an essential objective. When developing power transformers, industrial electric motors, and welding equipment, the choice of conductor material is critical. Replacing conventional copper conductors with advanced enameled aluminum winding wires has become a global industry standard for optimizing equipment costs without reducing performance integrity.
FENITEC Factory manufactures and distributes premium APET-200 enameled round aluminum winding wire with a 1.70 mm nominal diameter, engineered specifically for demanding thermal and mechanical operating environments.
Designation Breakdown of APET-200
Each letter and figure in the product specification defines its technical capabilities:
A (Aluminum): High-conductivity, high-purity electrical-grade aluminum conductor core.
P (Wire): Designed specifically for electromagnetic coils and winding assemblies.
E (Enameled): Multi-layered synthetic enamel film providing reliable insulation.
T (Thermal-resistant): Enhanced resistance to prolonged high-temperature exposure.
200 (Thermal Index): Retains its dielectric strength and mechanical flexibility under continuous operational temperatures up to 200°C (Thermal Class 200 / Class C).
d 1.70 mm: Precise 1.70 mm nominal conductor diameter.
Key Technical Advantages of APET-200 (1.70 mm)
Cost Efficiency: Aluminum offers a substantial cost advantage over copper, lowering magnet wire raw material expenditures by 30–40% and increasing final product price competitiveness.
Significant Weight Reduction: Aluminum has approximately one-third the density of copper. This reduces the total structural weight of large dry-type and oil-immersed transformers, simplifying assembly and lowering transport costs.
High Enamel Flexibility & Adhesion: The specialized polyesterimide coating demonstrates high resistance to cracking, flaking, or crazing during automated high-tension coil winding processes.
Chemical and Dielectric Durability: The insulation layer resists deterioration from transformer cooling oils, industrial varnishes, and moisture, preventing turn-to-turn short circuits.
Industrial Applications
APET-200 wire (1.70 mm diameter) is widely deployed in the following segments:
Primary and secondary windings of oil-immersed and dry-type distribution transformers;
Industrial and commercial arc welding machine transformers and inductors;
Heavy-duty asynchronous electric motors and generators;
Smoothing chokes, industrial reactors, and voltage stabilization equipment.
