Core Product Features & Technical Advantages:
- Superior Material Composition: Copper Clad Aluminum combines the excellent conductivity of a copper outer layer with the lightweight and cost benefits of an aluminum core, ideal for transformer windings where weight and material cost are significant factors.
- High-Temperature Endurance (Class 180/H): The specialized enamel insulation withstands continuous operating temperatures up to 180°C, ensuring long-term reliability and stability in high-heat transformer environments, preventing premature insulation breakdown.
- Enhanced Electrical Performance: Features low dielectric loss, high breakdown voltage, and excellent corona resistance, crucial for maintaining transformer efficiency and minimizing energy losses.
- Mechanical Durability: The enamel coating provides exceptional resistance to abrasion, solvents, and chemicals encountered during winding processes and transformer operation, ensuring mechanical integrity.
- Optimized Flexibility & Winding Efficiency: The round shape and consistent enamel coating allow for smooth, tight winding on transformer cores, maximizing space utilization and simplifying manufacturing processes.
- Cost-Effective Solution: CCA offers significant material cost savings compared to pure copper wire, while still delivering robust electrical performance suitable for many transformer designs, improving overall project economics.

Frequently Asked Questions (FAQ):
-
Q: How does Copper Clad Aluminum (CCA) wire compare electrically to pure copper wire for transformers?
A: CCA wire has a higher DC resistance per unit length compared to the same diameter pure copper wire (typically around 1.6 times higher). However, for many transformer applications, especially where cost and weight are critical factors, and the design can accommodate the slightly higher resistance, CCA offers a very viable and economical alternative. The copper cladding ensures good surface conductivity and solderability. -
Q: Is Class 180 (H) insulation sufficient for my transformer application?
A: Class 180 insulation is designed for continuous operation at 180°C, making it suitable for a wide range of power and distribution transformers, as well as other electrical equipment operating under significant thermal stress. If your application involves extreme temperatures or specific environmental conditions, consult our technical team to confirm suitability. -
Q: Can you provide wire with specific diameters or tolerances outside the standard range?
A: Yes. As a manufacturer with significant production capacity, we specialize in customization. We can produce Class 180 CCA Enameled Wire in a wide range of conductor diameters and with tight tolerances to meet your precise transformer winding specifications. Please provide your detailed requirements. -
Q: What are the key advantages of using CCA wire over pure aluminum wire?
A: While pure aluminum is lighter and cheaper than copper, CCA wire offers significant advantages: superior surface conductivity (like copper), much better solderability and termination characteristics, improved resistance to oxidation at connection points, and generally better mechanical strength and handling properties during winding compared to pure aluminum. -
Q: What packaging options are available for bulk orders?
A> We offer various packaging solutions to protect the wire during transit and facilitate handling in your factory. Common options include spools, reels, or cartons. Packaging size and type can be customized based on order volume and your specific handling equipment requirements. -
Q: Do you offer different types of enamel insulation besides the standard for Class 180?
A: Yes. While our standard Class 180 wire uses high-temperature resins like polyesterimide (PEI) or polyamide-imide (PAI), we can produce wire with other insulation systems (e.g., modified grades) upon request to meet specific chemical resistance, flexibility, or thermal index needs. Discuss your application with us. -
Q: How does your quality control process ensure consistent wire performance?
A> Our ISO 9001 certified quality management system governs the entire production process. We implement rigorous in-process testing and final inspection, including checks for conductor diameter, insulation build, continuity, dielectric strength, elongation, and thermal performance, ensuring every batch meets our stringent standards and customer specifications.
