Frequently Asked Questions
Q1: What is the difference between bare and insulated copper stranded wire?
A: Bare copper wire is uncoated, ideal for grounding and overhead applications where insulation isn't required. Insulated wire features a protective layer (e.g., PVC or XLPE) to prevent short circuits and corrosion, suitable for indoor wiring or harsh environments.
Q2: What certifications does this wire have?
A: Our wire complies with ISO 9001, CE, CCC, RoHS, UL, and VDE standards, ensuring safety and performance reliability.
Q3: Can I customize the wire stranding and insulation?
A: Yes! We offer customizable stranding (7-61 strands), insulation materials, colors, and packaging to meet specific project needs.
Q4: What is the minimum order quantity (MOQ)?
A: MOQ starts from 50kg, with bulk discounts available for larger orders.
Q5: How is the wire packaged and delivered?
A: We pack wires in durable drums or reels and ship globally via FOB/CIF terms. Lead time is typically 15 days.
Q6: Why choose copper over other conductors?
A: Copper offers superior conductivity, flexibility, and corrosion resistance, making it cost-effective for long-term use in high-efficiency systems.
