Explore our flagship enameled conductor lines engineered for high-performance motors, transformers, and industrial applications.
In the global market of electromechanical manufacturing, Polyester Coated Copper Wire (commonly classified as PEW or Polyester Enameled Wire) represents the foundational core of modern energy conversion. Serving as the primary conductive media inside electric motors, high-frequency transformers, relays, and solenoids, this highly engineered magnet wire must endure intense thermal, chemical, mechanical, and electrical stresses.
As a leading enterprise in this industry, Suzhou Daiming Electrical Materials Co., Ltd. specializes in the synthesis, draw-down, and application of specialized polymer coatings onto high-purity electrical-grade conductors. Operating from a state-of-the-art facility, we implement rigorous quality controls to ensure our enameled copper and aluminum wire configurations achieve peak performance metrics globally.
The performance of enameled magnet wire relies heavily on the characteristics of the chemical insulation layer. A standard Polyester Coated (PEW) layer is composed of modified polyterephthalate resins, which are cured at high temperatures to form a highly crosslinked, three-dimensional thermosetting network. This structure provides key operational advantages:
China has established the most complete supply chain ecosystem for enameled wire, offering key advantages for international procurement:
At Suzhou Daiming Electrical Materials Co., Ltd., customer needs are the core of our operations.

Our enameled conductors are designed to support energy-efficient motors, reducing electrical losses in next-generation green applications.
Enameled wires are categorized based on conductor material, cross-sectional geometry, and thermal rating class. Selecting the correct configuration is essential for maximizing efficiency while preventing premature dielectric breakdown.
Enameled aluminum wire is widely used in cost-sensitive, weight-critical applications. Since aluminum has approximately 61% of the conductivity of copper, it requires slightly larger wire cross-sections but offers a significant weight reduction (roughly 50% lighter than copper for the same length).
Primary Applications: Microwave oven transformers, air conditioner compressors, generator stator coils, and lightweight automotive components.
Enameled copper wire is the industry standard for high-efficiency electrical equipment. Its high conductivity ensures minimal resistance loss (I²R loss), making it suitable for applications with space constraints and strict thermal limits.
Primary Applications: High-performance EV traction motors, high-frequency power supply transformers, industrial servo motors, and precision audio equipment.
CCA enameled wire features an aluminum core metallurgically bonded to an outer copper sleeve. This hybrid configuration combines the high conductivity and solderability of copper on the surface with the lightweight advantages of an aluminum core, making it ideal for high-frequency signal systems.
Primary Applications: High-frequency coils, deflection yokes, CATV coaxial cables, and domestic electronic appliances.
CTC consists of multiple individual enameled rectangular copper wires arranged in a specific transposed pattern, wrapped in high-purity insulating paper or mesh. This configuration reduces eddy-current losses in power transformers and minimizes hot-spot temperatures.
Primary Applications: Large wind-power generators, high-voltage power transmission transformers, and heavy-duty industrial power machinery.
