Engineered for heavy-duty industrial automation, electric power distribution, and high-frequency appliances.
In today's highly volatile industrial metals market, optimizing raw material costs while keeping system electrical efficiency at peak performance is the ultimate priority for electrical system designers. Enameled Copper Clad Aluminum (CCA) Wire is the paramount solution to this challenge. Formed through a metallurgical cladding technique where a continuous, seamless outer sleeve of oxygen-free copper is molecularly bonded to a solid high-purity electrical-grade aluminum core, CCA balances the best properties of both elements.
At high frequencies, electrical currents tend to flow primarily on the outer skin of the conductor—a phenomenon known as the skin effect. Since the outer cladding of CCA is pure copper, it matches the electrical performance of solid copper conductors in high-frequency applications while utilizing a lightweight aluminum interior. This reduces overall weight by 35% to 40% and yields massive logistical and manufacturing cost advantages for large-scale production facilities worldwide.

Crucial engineering answers regarding Enameled CCA, Aluminum, and Copper wire designs.
The terms 10A and 15A refer to the volume ratio of the copper cladding. 10A contains approximately 10% copper by volume (amounting to ~27% by weight), whereas 15A contains 15% copper by volume (~37% by weight). 15A offers higher electrical conductivity and lower resistance, making it suitable for applications requiring greater current density.
Yes. Because the outer cladding is pure copper, enameled CCA wire can be soldered easily using standard lead-tin or lead-free solders at typical soldering temperatures. Special flux formulations required for raw aluminum are not necessary, allowing seamless integration with existing terminal components.
Enameled CCA wire is about 60% lighter than solid copper wire of the same diameter. This massive weight savings lowers mechanical stress on motor bearings, reduces transit costs, and helps prevent shipping damage during handling.
We manufacture enameled wires across thermal classes 130°C, 155°C, 180°C, 200°C, and 220°C. Common insulation varnishes include Polyurethane (UEW), Polyester (PEW), Polyesterimide (EIW), and Polyamide-imide (AIW) overlays.
