C11000 Copper Electrical Stranded Conductors Wire
The C11000 copper alloy is known for its high purity, typically containing more than 99.9% elemental copper, which gives it a unique set of physical and chemical properties. First and foremost, its excellent electrical conductivity makes C11000 copper alloy an indispensable material in the electrical and electronics industry. During the transmission of electrical current, high purity copper minimizes energy loss and improves energy efficiency.

Key Features
Ultimate Conductivity: Made of C11000 (Cu-ETP), ensuring minimal resistance and maximum current carrying capacity.
Precision Stranding: Concentric lay stranding ensures a smooth surface, tight diameter tolerance, and prevents "bird-caging" during installation.
Corrosion Resistant: Forms a natural patina that protects the internal strands, suitable for outdoor and buried grounding applications.
Versatile Tempers: Available in Soft Drawn (Annealed) for flexibility in grounding, and Hard Drawn for high tensile strength in overhead spans.
Temper Selection Guide: Soft vs. Hard Drawn
| Feature | Soft Drawn (Annealed) | Hard Drawn (Unannealed) |
| Flexibility | High (Easy to bend and route) | Low (Stiff and rigid) |
| Tensile Strength | Lower | Higher (Resists stretching) |
| Primary Use | Grounding Systems (Earthing), Jumper Cables, Panel Wiring. | Overhead Transmission Lines, Long Spans where sag must be minimized. |
| ASTM Standard | ASTM B3 | ASTM B1 |
Manufacturing & Quality Assurance
DC Resistance Test: Every batch is tested to ensure resistance meets IEC 60228 limits.
Tensile Testing: Verified breaking load for hard-drawn specifications.
Visual Inspection: 100% surface check to ensure no scratches, burrs, or oxidation spots."
Application areas of C11000 pure copper wire
Power transmission: C11000 copper stranded wire is widely used in high and low voltage power transmission systems to ensure a stable and reliable power supply.
Electrical equipment connection: It is suitable for connecting cables inside or outside of various electrical equipment, such as motors and transformers.
Communication cables: Due to its good signal conduction ability, it can be used to manufacture communication cables to ensure the accuracy and real-time data transmission.
Packaging & Delivery
Wooden Drums: For long lengths, we use fumigated wooden drums (Reels) suitable for forklift handling and cable payout machines.
Protective Lagging: Drums are lagged with wooden planks or PP sheets to protect the outer layer of copper during transport.
Coils: Smaller lengths (e.g., 100m) can be supplied in shrink-wrapped coils.
Identification: Metal tags indicating Size (mm²/AWG), Length, Net Weight, and Batch No."
