📐 Custom Orders: We can customize the cross-sectional area according to specific requirements, with single wire diameters ranging from 0.05mm to 0.15mm. Braided wires are produced using specialized 8-spindle or 12-spindle machines. Cutting lengths are based on your drawings or specifications.
Frequently Asked Questions
Q
What is flexible stranded copper wire and how does it differ from solid-core wire?
Flexible stranded copper wire is composed of multiple fine copper wires twisted together. This construction gives it superior flexibility, fatigue resistance, and ease of installation compared to stiff solid-core wire, which is more prone to breaking under repeated bending.
Q
What purity level is the copper used in these wires?
The conductor is manufactured from high-purity electrolytic copper with a purity of Cu ≥ 99.9%. This ensures excellent electrical conductivity and compliance with international standards.
Q
What coating options are available for the copper strands?
Three main options are available: Bare Copper (economical), Tinned Copper (anti-oxidation and improved solderability), and Silver-Plated Copper (for high-frequency or low-contact-resistance applications).
Q
What cross-sectional sizes and individual wire diameters are available?
Standard nominal cross-sectional areas range from 0.55 mm² to 25.00 mm². Individual wire diameters range from 0.05mm to 0.2mm. Custom sizes can be produced with single wire diameters from 0.05mm to 0.15mm.
Q
What insulation materials can be used for these wires?
Available materials include PVC, XLPE, Silicone Rubber, EPR, and Fluoropolymers. Each material offers different temperature ratings and chemical resistance to suit specific environment needs.
Q
Are custom lengths and specifications available?
Yes, full customization is offered including specific cross-sectional areas, strand counts, wire diameters, and precision cutting lengths based on project drawings or technical specifications.
