Explore our core selection of heavy-duty paper insulated, ultra-high thermal class enameled flat copper, and high-performance transposed conductors.
In the modern landscape of high-efficiency machinery, Enameled Copper Winding Wire represents the core element of power generation, electrical transmission, and precision motion control. Global procurement agencies look beyond simple material sourcing. They seek reliable manufacturers capable of withstanding strict mechanical stress, thermal fluctuations up to Class 240, and intense dielectric pressure.
Whether it is implementing continuous processing lines for EV traction motors or building high-capacity substations, material consistency is non-negotiable. Our engineering process eliminates micro-voids in the wire structure and provides a uniform enamel film coating. This results in minimal dielectric loss, increased slot fill factor, and excellent winding reliability even under severe tension.
We stabilize raw material supplies through long-term partnerships with certified grade-A copper cathode refineries. Our supply chains offer stable pricing frameworks to shield global projects from unexpected raw material price shifts.

Our enameled wires are used in core areas such as high-efficiency and energy-saving motors, helping reduce energy losses and carbon footprints.
Our products support diverse electrical systems, powering critical equipment in global industries.
The shift toward 800V EV architectures requires magnet wire capable of resisting corona discharges. Our 220-class enameled flat copper wire is designed for traction motors, providing high thermal stability and corona resistance under high-voltage stress. The flat profile maximizes the slot fill factor, increasing motor torque density and overall vehicle efficiency.
For large-scale electrical grids, reducing eddy-current loss is key to system efficiency. Our Continuously Transposed Conductors (CTC) group multiple insulated strands in a transposed layout, reducing electromagnetic losses and improving cooling. This design helps minimize hot spots in heavy-duty, oil-immersed power transformers.
Modern offshore and onshore wind turbine generators operate under high vibration and high humidity. Our paper-covered flat copper wires and high-temperature class enameled aluminum wires resist insulation breakdown under constant thermal cycle loads, maintaining reliable grid connections in harsh environments.
Precision sensors, high-speed actuators, and industrial servomotors rely on lightweight wires with consistent properties. Our Enameled Copper Clad Aluminum (ECCA) wires combine the conductivity of copper with the light weight of aluminum. This helps reduce rotational inertia in moving robotic arms while maintaining performance.

Developing next-generation insulation systems designed to handle higher voltages and thermal limits.
With electric vehicles moving to 800V drivetrains, winding wires face increased stress from rapid voltage rises. We are developing polymer-silica nanocomposite coatings to extend insulation life and prevent premature breakdown under high frequency and voltage stress.
By applying a polyimide topcoat over a high-performance polyesterimide base, we create winding wires rated up to 240°C. This hybrid layer offers excellent chemical resistance to transformer oils, fluorocarbon refrigerants, and moisture.
We are working to improve the copper-to-aluminum ratio in our Copper-Clad Aluminum (CCA) wires. This research aims to match standard copper conductivity at high frequencies while reducing weight, helping to lower shipping costs and raw material usage.
Our manufacturing facility operates under strict quality management systems to meet international electrical safety standards.
Ensuring process control and traceability from raw wire rod input to final product spooling.
