Polyester Enameled Round Aluminum Wire(PEW, 155°C)

Product Overview

Enameled round aluminum wire uses high-purity aluminium as the conductor in place of copper, reducing conductor weight by roughly 60% at equivalent volume. This makes it an economical and lightweight choice for transformers, reactors and large rotating machines where weight and material cost are decisive, and where winding space rather than conductor cross-section is the limiting factor.

Huaya Fa (Foshan) Technology Co., Ltd. supplies enamelled round aluminium wire from 0.13 to 3.50 mm across the 155, 180, 200 and 220 thermal classes, using polyester, polyester-imide and polyamide-imide insulation systems.

Key Advantages

• Dual manufacturing hubs in Changzhou and Foshan, China, covering both fine-gauge and heavy-gauge production.
• Full production range from 0.04 mm to 2.50 mm, supporting everything from micro-motors to large power equipment.
• Monthly output of approximately 3,000 tons, with stable capacity for repeat and high-volume programmes.
• ISO 9001 and ISO 14001 certified quality and environmental management systems.
• RoHS and REACH compliant insulation systems for European and North American markets.
• Wire manufactured in accordance with IEC, NEMA, GB and JIS international standards.
• Conductor weight reduced by approximately 60% compared with copper at equal volume.
• Lower and more stable raw material cost for price-sensitive transformer programmes.
• Larger conductor cross-section for the same mass, improving slot fill in fixed winding windows.

Product Features

• High breakdown voltage and excellent dielectric strength.
• Good resistance to common solvents, refrigerants and transformer oils.
• Adhesion and flexibility suitable for high-speed automatic winding.
• Abrasion-resistant enamel film produced on vertical enamelling lines.
