Standard polyester coatings provide outstanding thermal stability, often operating continuously at temperature classes up to 220°C. These coatings are resilient against chemical agents, environmental weathering, and thermal shocks, making them suitable for demanding motor windings and industrial hardware.
When used on wire surfaces or chain-link systems, polyester provides a highly uniform, micro-thin insulating barrier. This guarantees a high breakdown voltage while retaining low overall electrical loss, critical for high-efficiency motors, generators, and heavy transmission systems.
Our specialized application process ensures that the polyester layer adheres seamlessly to the metal substrate. Whether subjected to complex winding stress, high-tension pulling, or mechanical vibration, the coating prevents cracking, peeling, or micro-fracturing.
Suzhou Daiming Electrical Materials Co., Ltd. stands as a premier manufacturer and global supplier of high-quality insulated conductors. Our extensive product portfolio includes advanced enameled aluminum wires, enameled copper wires, and copper-clad aluminum enameled wires tailored to cross-industry technical requirements.
Our facility spans a sprawling 258,333.33 ft² production site, housing 30 state-of-the-art production lines. This highly robust infrastructure allows us to maintain a consistent output, securing supply chains for global enterprise clients. With stringent quality controls active at every stage—from chemical coating validation to inline laser dimension monitoring—we guarantee zero-defect material performance.
Our engineering team brings more than ten years of focused experience to the field, possessing deep knowledge of international norms, molecular polymer coatings, and high-speed drawing and winding technologies.
By securing high-grade raw aluminum and cathode copper from regional smelters, we eliminate supply chain lag. Our adjacent chemical coating partners supply specialized polyester and polyamideimide resins directly to our application line.
Our facility runs multi-stage drawing machines and catalytic combustion heating ovens. This configuration guarantees precise wire diameters, uniform coating application, and energy recovery, keeping production costs highly competitive.
Strategically located in Suzhou, China, we have immediate access to world-class ports like Shanghai and Ningbo. We manage customs clearances, freight bookings, and container tracking to optimize transit timelines for our clients.
To supply international aerospace, automotive, and grid networks, materials must meet strict regulatory thresholds. Suzhou Daiming ensures all enameled wires and custom-coated products fully comply with:
We supply dedicated technical consulting, customized packaging sizes (tapered spools, structural drums), and on-site integration support through regional distributors.
| Insulation Base Type | Thermal Class | Primary Application Areas |
|---|---|---|
| Polyester (PEW) | 130°C / 155°C | General home appliances, control sensors |
| Polyesterimide (EIW) | 180°C | Industrial drive motors, power tool motors |
| Polyesterimide + Polyamideimide (EIW/AIW) | 200°C / 220°C | Traction motors, 800V EV drivetrains |
| Paper Insulated / CTC | Up to Class H | High-voltage grid transformers, power generators |
Supplying critical winding material to dynamic traction motors and heavy-duty grid transformers. Our products offer excellent paint layer adhesion and voltage resistance to prevent premature insulation failure.
Precision enameled copper and aluminum wires with low tolerances and high mechanical strength, designed for automated, high-speed winding machinery used in smart household products and micro-electronics.
Customized thin-gauge wires that exhibit stable chemical resistance and high flexibility. These properties protect signal integrity in harsh manufacturing environments and sensitive sensor setups.
Heavy-gauge Continuously Transposed Conductors (CTC) and paper-covered aluminum windings designed for major substations, clean energy installations, and large power distribution networks.
Modern electric vehicle drivetrains are transitioning from 400V structures to 800V architectures. This change allows for faster charging and lighter wiring harnesses, but increases the risk of partial discharges and corona-induced degradation of the insulating layers.
To address this challenge, Suzhou Daiming is developing specialized multi-layered enameled magnet wires. These feature a blend of polyesterimide and polyamideimide polymers designed to resist severe voltage rises (high dV/dt) and maintain insulation integrity over the vehicle's lifespan.
In line with global environmental goals, we have integrated closed-loop solvent recovery units on our curing lines. This system captures and combusts volatile organic compounds (VOCs) to generate process heat, minimizing emissions and lowering our overall carbon footprint.
We have completed the shipment of a new batch of high-quality Continuously Transposed Conductors (CTC) to Turkey to support regional power grid upgrade projects.
With raw material fluctuations remaining high, we present our optimized enameled aluminum wire lineup designed to optimize design budgets.
Copper-Clad Aluminum (CCA) enameled wire balances electrical conductivity with weight reduction benefits in high-frequency applications.
