Model And Meaning

Advantages

Effective Vibration Damping Flexible multi-strand structure reduces self-vibration and impact during momentary energization; connections stay tight.

Efficient Current Conduction Annealed Cu-ETP (≥99.95%) minimizes skin effect losses and ensures fast response.

Complex Bending Motion Suitable for dynamic environments; withstands repeated bending without fatigue failure.

Compact & Small Bending Radius Provides a significantly smaller bending radius than rigid copper bars of identical cross-sections.

Easy Confined-Space Installation Flexible construction eliminates cumulative installation tolerances for smooth routing in tight, irregular areas.

Balanced Heat Dissipation Avoids localized overheating caused by molecular lattice damage during cold-bending processes.

Operating & Maintenance

Temperature Range: –40°C to +200°C (tin-plated)

Service Life: 10–15 years under normal dry indoor conditions.

Inspection: Bare copper in humid environments should be inspected every 6–12 months; the tin-plated version requires minimal care.

Vibration Maintenance: Check terminal tightness annually in high-vibration installations.

Standard Compliance: Compliant with GB/T12970.2-2009, cross-sectional area 1.5–2000 mm².

Packaging: Rolls, spools, or wooden drums.

Applications

Used for flexible conduction and grounding connections in electrical installations, switchgear, electric furnaces, storage batteries, etc. Widely applied in new energy “solar-storage-charging”, new energy vehicle drives, wind power generation, and more.

Frequently Asked Questions (FAQ)

1. What is the raw material quality of Bridgold copper stranded wires?

Our wires are manufactured from high-purity annealed Cu-ETP (C11000) with a guaranteed copper content of ≥ 99.95%, ensuring maximum electrical conductivity and minimal skin effect losses.

2. What operating temperature can the insulated stranded copper wire withstand?

The tin-plated versions can operate reliably within an operating temperature range of -40°C up to +200°C, making them suitable for severe electrical and industrial environments.

3. What insulation colors and custom options are available?

Standard PVC insulation colors include transparent, green, yellow, blue, and red. Custom colors, customized wire diameters, and specific cross-sectional areas (from 1.5 mm² to 2000 mm²) can be manufactured upon request.

4. How often should flexible copper connections be inspected?

Bare copper used in humid environments should undergo visual inspection every 6 to 12 months. Tin-plated wires require minimal maintenance, with annual checks recommended for terminal tightness in high-vibration applications.

5. What are the key industrial applications for these stranded copper wires?

They are ideal for flexible conduction and grounding in switchgear, electric furnaces, energy storage systems, new energy EV drives, and solar/wind power generation installations.

6. What standard certifications do these copper wires comply with?

All products fully conform to the GB/T12970.2-2009 standard, ensuring industry-grade structural integrity, electrical conductivity, and long operating service life.
