Why modern industries choose Daiming's engineered hybrid composite wires over conventional alternatives.
In high-frequency power transmission and high-speed rotary electrical units, weight and heat accumulation are the core challenges of system efficiency. While copper provides excellent conductivity, its weight and susceptibility to high-frequency "skin effect" limit further performance enhancements. Conversely, pure aluminum, though lightweight, suffers from high resistance and mechanical fragility. Suzhou Daiming's Copper Clad Aluminum (CCA) and special Aluminum Coated Copper Wire bridge this critical engineering gap.
By metallurgically bonding a dense layer of oxygen-free copper over a premium grade electrical aluminum core, our wire combines the electrical efficiency of copper at high frequencies with the lightweight mechanical structure of aluminum. As currents shift to the outer layer (skin effect) at high frequencies, the copper outer layer serves as the primary conduction path, offering performance levels matching pure copper at up to 40% reduction in weight and significantly lower material costs.

Explore CTC Solutions →As the automotive sector transitions from 400V to 800V architectures, corona discharge and dielectric breakdown present major risks. Daiming's custom 220 Class polyamide-imide over Polyesterimide enameled wires provide exceptional partial discharge resistance and thermal endurance for high-stress traction motors.
For grid-scale transformers, eddy current losses inside massive copper sections reduce system efficiency. By transposing individual enameled rectangular conductors into continuous CTC cables, our solutions reduce stray-field losses, lower operating temperatures, and extend the lifespan of high-capacity transformers.
High-frequency communication lines leverage the skin effect, transmitting signals primarily on the conductor surface. Our CCA wires, featuring a uniform, metallurgically bonded outer copper shell, provide high conductivity at a fraction of the weight, simplifying mast installations and reducing infrastructure load.
Optical emission spectrometry checks raw rod purity before processing.
Laser gauges continuously monitor outer diameter tolerances and roundness.
Continuous high-voltage spark tests detect micro-pinholes or defects in insulation.
Mechanical checks verify ductility, ensuring ease of automatic winding.
