Explore our leading selection of enameled wires and custom CTC configurations designed for ultra-high voltage grids and motor winding systems.
The foundation of modern power generation, high-frequency signal processing, and electromagnetic conversions.
Known for excellent solderability. It decomposes at high temperatures during soldering, eliminating the need to pre-strip insulation before termination. Highly popular in small electronics and instrumentation.
Offers superior thermal stability. Typically rated at Class H (180°C), providing deep thermal resistance, exceptional breakdown voltage capacity, and chemical resilience for heavy machinery and power tools.
Provides premium scratch resistance and windability. The dual-layer configuration (PEI basecoat + PAI topcoat) yields Class 200/220 thermal grades, ideal for high-stress aerospace and EV traction motors.
Suzhou Daiming Electrical Materials Co., Ltd. is a premier manufacturing enterprise of high-performance enameled wires, specializing in enameled aluminum wire, enameled copper wire, and enameled copper-clad aluminum wire. Backed by state-of-the-art infrastructure, our facility addresses complex manufacturing challenges to serve clients globally.
Spanning an expansive 258,333.33 ft² production site, we operate 30 advanced production lines. This robust configuration guarantees high-volume output and uniform delivery timelines. Our operations prioritize quality, with strict inspections implemented from the evaluation of incoming raw materials to final validation checks before shipment.
Exploring Daiming's four core product lines engineered to exceed international standards like IEC, NEMA, and JIS.
A lightweight, cost-efficient alternative to copper. Highly favored for weight-sensitive applications such as microwave oven transformers, automotive fans, and high-frequency communication coils.
The gold standard in electrical conductivity. Perfect for high-efficiency motors, micro-electronics, generators, and heavy duty industrial winders needing maximum electrical efficiency.
Combines the light weight of aluminum with the solderability and contact reliability of copper. Helps reduce costs during volatile copper price surges.
Engineered for large power transformers. Made of a bundle of enameled rectangular wires transposed systematically to minimize eddy current losses at grid-scale currents.

Operational excellence, material science expertise, and robust supply chain integration.
Each batch undergoes inline laser diameter checks and high-voltage continuity testing. This ensures insulation layer concentricity and minimizes pinhole faults per 30 meters.
Our enameled wires feature uniform paint films, high flexibility, scratch resistance, and strong adhesion, preventing cracks even under tight-mandrel winding stresses.
We support precise tailoring of conductor sizes and wire shapes—including round and rectangular cross-sections—to meet specific slot-fill factor requirements.
Utilizing 30 advanced production lines on our 258,333.33 ft² site, we secure consistent batch manufacturing and container packing to prevent transit damage.
Our processes prioritize VOC catalytic recycling, converting paint solvent emissions into thermal energy for ovens. This sustainable approach helps reduce carbon footprints across downstream supply chains.
Engineered for extreme performance in demanding electrical systems worldwide.
