Engineered to meet the stringent technical requirements of high-voltage grids and heavy industrial transformers in Switzerland.
Switzerland is internationally renowned for its pioneering role in power engineering, electrical grids, and high-precision industrial machinery. With the ongoing deployment of the "Swiss Energy Strategy 2050" and the upgrading of the Swissgrid high-voltage transmission network from 220kV to 380kV substations, the demand for top-tier winding materials has reached unprecedented heights.
Locally established global heavyweights in power grid systems—such as those operating in Baden, Zurich, and Geneva—require highly reliable, thermal-class certified winding wires that can withstand extreme electrical stress and structural vibrations. The thermal and dielectric efficiency of paper-covered flat wire directly dictates the operational lifespan and safety margins of heavy-duty distribution and power transformers.
Our solutions target these specific industrial needs, offering localized engineering support, fast compliance audits, and advanced supply logistics tailored to Swiss technical standards (including IEC and Swissgrid specs).
What Swiss electrical engineers seek in high-reliability paper covered rectangular conductors.
Engineered with multi-layered, highly-densified, thermally stabilized sulfate wood pulp paper. Our wrapping ensures low dissipation factor and high oil impregnation performance under extreme thermal loads.
Utilizing high-purity copper cathodes (99.99%) or oxygen-free (OF-Cu) raw materials to guarantee minimal electrical resistance, reduced power losses, and superior heat dissipation characteristics.
Using digital laser gauge technology on our modern drawing lines to maintain extremely narrow flat wire dimensional tolerances, ensuring compact coils and optimal space factor in Swiss-designed transformers.
Customer needs act as the absolute core of our operation. Suzhou Daiming Electrical Materials Co., Ltd. is a global leader in high-performance winding wires, including paper covered flat wire, enameled aluminum/copper wires, and advanced continuous transposed conductors (CTC).
Our expansive industrial complex features state-of-the-art machinery capable of handling custom insulation specs, tight geometric tolerances, and rigorous test procedures dictated by European and North American buyers. Our expert R&D team boasts over ten years of dedicated industry experience, deeply understanding IEC standards, oil-immersion dynamics, and short-circuit mechanical stresses.
Why leading global manufacturers trust Suzhou Daiming as their long-term supply partner.
The manufacturing plants of Suzhou Daiming operate on a highly integrated Smart Winding Production System. Under China's Industry 4.0 framework, we have optimized our supply chains to insulate our Swiss and European partners from sudden raw material volatility and logistics delays. From precision copper drawing to automated kraft paper tension wrapping, each stage is digitally tracked to ensure total batch traceability.
For Swiss engineering companies, this means guaranteed lead times, constant material properties compliance, and seamless customs documentation. Our proximity to key deep-water shipping lanes and robust international freight connections ensures that our paper covered flat wire reaches industrial hubs in Zurich, Geneva, or Basel with optimal speed and integrity.
