Copper Stranded Cables for Electrical Connections and Earthing Systems

Product Overview

Our company produces high-quality bare copper stranded cables for electrical connections and earthing systems. Our main products include:

Bare Copper Stranded Cable from 25mm² to 125mm² in 100-metre coils

Custom Production

We are able to produce copper stranded cables in various cross-sections and specifications upon customer request, adapting to the specific needs of each project.

General Specifications

  • Material: Annealed red electrolytic copper, 99.9% purity
  • Flexibility class: Class 2 according to IEC 60228
  • Maximum operating temperature: 90°C
  • Short-circuit temperature: 250°C
  • Minimum bending radius: 6 times the outer diameter
  • Regulatory compliance: CEI 20-29, CEI 64-8, IEC 60228

Technical Advantages of Copper

  • Second only to silver in electrical conductivity
  • 30-50% greater current-carrying capacity compared to aluminium at the same cross-section
  • Voltage losses reduced by 65% compared to aluminium conductors
  •  
    • Maximum tensile stress: 50 N/mm²
    • Mechanical properties retained even at low temperatures
    • High fatigue resistance for repeated bending
  • Excellent resistance to atmospheric oxidation
  • Formation of a natural protective film that prevents deep corrosion
  • Long service life even in aggressive environments
  •  
  • High ductility and malleability for complex installations
  • Ease of rolling and processing
  • Excellent weldability for secure connections
  • Drawability into very fine diameters
    •  
  • Connection stability over time
  • Low incident rate compared to other conductive materials
  • Not susceptible to joint oxidation issues
  • Compatible with all standard connection systems
