Additional Material Information
Base Conductor
Annealed Cu‑ETP wires (C11000, copper content ≥99.95%), braided per GB/T6313.2-1992.
End Termination
Welded and hot-dip tinned for secure, low-resistance contact.
Insulation Materials
PVC (general purpose), TPE (flexible & halogen-free), glass fiber (high temperature), silicone rubber (flexible & high temp), silicone rubber + glass fiber (mechanical & thermal protection).
Technical Data (Typical)
Single Wire Diameter:
0.05 mm – 0.254 mm (AWG 44 to 30), default 0.15 mm.
Cross Sectional Area:
1.5 mm² – 6000 mm² (Copper Braided Connectors); 1.5 mm² – 2000 mm² (Copper Stranded Connectors).
Temperature Range with Insulation:
Depends on material.
Voltage Rating with PVC Insulation:
600V to 1500V (depending on wall thickness and grade). For silicone/glass fiber, higher ratings are available.
Operating Conditions
- Suitable for indoor and outdoor applications with appropriate insulation.
- Withstands vibration, flexing, and moderate chemical exposure depending on insulation choice.
- Flame retardant ratings available (e.g., UL94 V-0 for PVC and silicone).
- Do not exceed maximum continuous operating temperature of the selected insulation.
Maintenance & Service Life
Maintenance:
Periodically inspect insulation for cracks, abrasion, or discoloration. Clean with a dry cloth or mild detergent – avoid solvents that may damage the insulation.
Service Life:
Base copper braid >20 years under normal conditions; insulation life varies by material.
Replace When:
Insulation becomes brittle, cracked, or melted; copper braid shows severe oxidation or broken strands.

Frequently Asked Questions (FAQ)
What are the primary advantages of adding insulation to copper braided connectors?
Insulation provides vital electrical safety, prevents accidental short circuits in compact installations, enhances dielectric strength, and protects the flexible copper strands against mechanical abrasion, moisture, chemical exposure, and extreme operating temperatures.
How do I select the best insulation material (PVC, TPE, Silicone, or Glass Fiber) for my project?
PVC is the most economical solution for general-purpose indoor electrical connections. TPE is recommended when halogen-free flexibility is mandatory. Silicone rubber provides high temperature resistance and flexibility, while glass fiber or silicone+glass fiber composite is ideal for high-temperature and harsh mechanical environments.
Can insulated flexible copper connectors be fully customized in size and configuration?
Yes, we provide comprehensive customization for cross-sectional area (1.5 mm² to 6000 mm²), overall length, single wire diameter, terminal hole punching, tin plating, and specific insulation sleeve color coding.
What voltage ratings do these insulated connectors support?
Standard PVC insulation typically supports continuous ratings from 600V to 1500V depending on wall thickness and grade. For medium-to-high voltage demands, specialized silicone rubber and glass fiber combinations are available.
What flame retardant ratings can be supplied?
We offer insulation compliant with standard industrial flame-retardant requirements, including UL94 V-0 ratings for PVC and silicone rubber configurations upon specification.
How should insulated copper connectors be inspected and maintained?
Inspect the outer sleeve periodically for surface cracking, melting, discoloration, or mechanical wear. Ensure cleaning is performed only using a dry cloth or mild detergent without abrasive chemical solvents.
