Soft Bare Copper Stranded Earth Cable (TJ Type)

In any electrical installation, the grounding system is the most critical factor for safety and equipment protection. CableApex provides premium Soft Bare Copper Stranded Earth Cable (TJ Type), engineered from high-purity electrolytic copper to ensure maximum conductivity and long-term durability in even the most challenging soil conditions.We control the quality from the very beginning—starting with high-purity electrolytic copper rods in our warehouse.

Organized inventory of semi-finished white cable spools on the factory floor, ready for processing. Massive inventory of premium copper rod raw materials for high-conductivity electrical wires. Bulk storage of plastic resin pellets and raw materials for high-quality cable insulation.

Uncompromising Material Purity

Not all copper is created equal. Our bare copper cables are manufactured using 99.9% pure copper, ensuring the lowest possible electrical resistance. This high degree of purity is essential for efficient lightning protection and system earthing, allowing fault currents to dissipate safely into the ground without damaging sensitive equipment.

The Foundation of Safe and Reliable Grounding Systems

In electrical infrastructure, the quality of the earth cable determines the safety of the entire system. CableApex’s bare copper stranded cables are manufactured using the highest grade of electrolytic copper to ensure maximum conductivity and corrosion resistance.

  • 99.99% Oxygen-Free High Conductivity (OFHC) Copper: We source only premium copper rods to produce our TJ type stranded cables. By maintaining a purity level of 99.99%, we ensure that our cables meet the strictest international standards for electrical resistivity (less than 0.01724 Ω·mm²/m at 20°C).

  • Annealed Soft Temper for Easy Installation: Our bare copper wires undergo a specialized annealing process to achieve a “soft” temper. This provides superior flexibility, making it significantly easier for contractors to bend and route the cable in grounding grids and lightning protection systems without compromising structural integrity.

  • Consistency Guaranteed by a 15-Year Manufacturer: Produced in our 20-acre facility in Yangzhou, our stranding process ensures perfect geometric symmetry. This consistency prevents local heating and ensures a stable path to ground for fault currents, protecting both personnel and sensitive equipment.

Technical Parameters & Options

We provide a comprehensive range of specifications to meet diverse engineering requirements:

  • Conductor Types: Choose between Solid Conductors (for rigid, permanent installations) and Stranded Conductors (for applications requiring greater flexibility).

  • Material Grade: High-conductivity electrolytic tough pitch (ETP) copper.

  • Standard Compliance: Fully compliant with IEC 60228 and ASTM B3/B8 standards.

  • Corrosion Resistance: Natural copper finish offers excellent longevity in most environments; tinned versions available for highly corrosive areas.

  • Size Range: Full spectrum of cross-sectional areas (mm²) and AWG sizes to match your project’s fault current ratings.

Primary Applications

This foundational electrical component is essential for:

  1. System Grounding: Main earthing for residential, commercial, and industrial power distribution.

  2. Lightning Protection: Down-conductors for lightning rod systems on high-rise buildings.

  3. Substation Infrastructure: Heavy-duty earthing grids for power plants and utility substations.

  4. Telecom & Data Centers: Dedicated grounding for sensitive electronic racks and telecommunication towers.
