Advantages
High Breaking Load: Manufactured with larger single wire diameters (1.70–2.85mm), providing significantly higher breaking load than fine-strand wires. Fully compliant with TB/T3111-2005, suitable for electrified railway catenary messenger wires, droppers, and long-span overhead lines.
High Tensile Strength: Hard-drawing process ensures mechanical strength meeting strict railway standards.
Excellent Conductivity: Copper content ≥99.95% ensures conductivity ≥97% IACS, reducing line losses.
Corrosion Resistance Option: Tin-plated finish resists sulfurization and humid corrosion, extending service life.
Customizable: Cross section, single wire diameter, plating, and packing can be tailored to customer needs.
Operating Conditions
Temperature range:
–40°C to +90°C (tin-plated)
Typical Applications: Electrified railway catenary systems, overhead transmission lines, substation busbars, grounding grids, high-current industrial connections, electric furnace and switchgear leads.
Precautions: Avoid direct burial in strong acid/alkali soil or prolonged water immersion for bare copper; tin-plated type withstands mildly corrosive environments.
Standard Compliance: Meets all mechanical and electrical requirements of TB/T3111-2005.
Precautions: Avoid direct burial in strong acid/alkali soil or prolonged water immersion for bare copper; tin-plated type withstands mildly corrosive environments.
Maintenance
Regularly inspect for oxidation, broken strands, or mechanical damage, especially at termination points.
For outdoor or railway use, perform cleaning and tightening checks every 12 months.
Avoid scratching tin coating; apply anti-oxidation grease on bare copper if needed.
Store in dry, ventilated warehouse away from acids, alkalis, salts, and damp floors.
