Frequently Asked Questions
Q
What types of composite conductors do you manufacture?
We manufacture four main types of composite conductors: bare flat composite wire, paper-covered composite wire, enameled composite wire, and film-wrapped composite wire. Each type is engineered to meet specific insulation and mechanical requirements for electrical applications.
Q
What is the maximum cross-sectional area available for flat wire conductors?
For flat wire conductors, the maximum cross-section is 200 mm², with thickness ranging from 1.00 mm to 12.00 mm and width from 3.00 mm to 25.00 mm. For bare, paper-wrapped, and film-wrapped composite conductors, the maximum cross-section is 150 mm².
Q
Can you customize conductor dimensions and insulation materials?
Yes. We fully support customization of conductor dimensions, insulation materials, and packaging types based on customer specifications. Our engineering team works closely with clients to ensure the final product meets both performance and application requirements.
Q
What applications are these composite conductors suitable for?
Our composite conductors are widely used in transformers, motors, reactors, and various other electrical and electronic equipment. Their reliable electrical performance, excellent insulation, and mechanical stability make them ideal for demanding industrial and power applications.
Q
What diameter range is available for round wire conductors?
Round wire conductors are available in diameters ranging from 2.00 mm to 5.00 mm. For enameled paper-covered and enameled composite wire, round conductors in the same 2.00–5.00 mm diameter range are recommended to ensure optimal insulation quality.
Q
How do you ensure the quality of your composite wire products?
All products are manufactured under strict quality control protocols, ensuring smooth surface finish, precise dimensional tolerances, and uniform insulation coating throughout each conductor. These standards guarantee consistent performance and long service life across all product lines.
