Engineered to comply with strict European power transformer specifications, optimized for local cold-start loads and wind generation integration.
Leading the Nordic energy transition with advanced electromagnetic winding technologies designed for maximum efficiency.
Sweden is globally recognized for its ambitious goals to transition to a completely fossil-free economy. Achieving this target requires a robust overhaul of electrical grid networks, clean energy infrastructure, and massive electric transportation systems. In this industrial setting, Paper Covered Flat Wires act as critical, silent drivers inside heavy-duty transformers, sub-stations, and high-frequency power plants.
Our specialized range of paper-wrapped flat copper and aluminum conductors is specifically designed to handle high mechanical stresses, severe thermal fluctuations, and continuous overloads common to Scandinavian onshore and offshore wind parks. By selecting high-density insulation paper (such as Kraft paper, thermally upgraded paper, and Crepe paper) and wrapping it with high precision over oxygen-free copper (OFC) or high-conductivity electrical aluminum, we guarantee long-term stability and minimal grid loss values.
Additionally, we supply Continuously Transposed Conductors (CTC) that significantly decrease eddy current losses in large power transformers, playing an indispensable role in Sweden's grid upgrade initiatives.
Customer Needs as the Core Winding Solution Provider
Suzhou Daiming Electrical Materials Co., Ltd. is a leading manufacturer specializing in premium electromagnetic wires, including enameled aluminum wires, enameled copper wires, and copper-clad aluminum (CCA) enameled wires, alongside our specialized paper-insulated flat wire line.
Operating a sprawling 258,333.33 ft² advanced manufacturing facility with 30 state-of-the-art automated production lines, we ensure a steady, high-volume supply to energy networks in over 10 countries. By conducting strict quality checks at every level—from raw material testing to micro-tolerance measurements—we deliver unmatched dependability and thermal efficiency to our Swedish and international client base.
Why leading Swedish transformer and electric motor manufacturers rely on our winding wire solutions.
We source premium kraft and crepe papers with high dielectric strength. Automated wrapping machines ensure overlapping insulation with zero gaps and uniform thickness to eliminate electrical failure risk.
Designed for thermal classes up to 120°C and 180°C (with special aramid fiber overlays). Engineered to handle high mechanical stress during distribution line short-circuit incidents.
Precise geometric dimensioning ranging from thicknesses of 1.0mm up to 8.0mm, and widths of 3.0mm up to 25.0mm. We tailor dimensional ratios and insulation layers to fit your core slot design.
Leveraging our 30 modern production lines, we guarantee consistent lead times. Each shipping batch is verified via traceability records and accompanied by international test reports.
100% compliant with RoHS and REACH initiatives. All paper materials are sourced from sustainable forests, ensuring minimal environmental impact across the entire material life cycle.
Powering clean energy systems, heavy industrial machinery, and future-ready transport grids.
Strategic directions for high-voltage systems, electric vehicle components, and smart electrical grids.
As the automotive and trucking sectors in Europe transition toward higher working voltages, winding wires must adapt. We are developing enameled and paper-wrapped hybrids designed for 800V EV drivetrains, which improve thermal dissipation and prevent insulation degradation from partial discharge events.
In step with circular economy goals, we are partnering with leading pulp mills to research high-purity cellulose and biodegradable polymer papers. This will reduce environmental impact at the end of a transformer's lifecycle while keeping breakdown voltage performance high.
Next-generation distribution grids require smart transformers that are smaller yet highly efficient. Our Continuously Transposed Conductor (CTC) technologies utilize thinner single wires wrapped in special epoxy-coated insulation, enabling compact transformer designs and lowering overall energy loss.
Our engineering team can calculate the optimal wire thickness, width, and insulation layers according to your electrical designs.
