Stranded conductors
Bimetallic stranded wire — construction and qualification
A stranded conductor is a complete construction. Specify the individual wires, finished geometry and electrical duty together.
Start with the actual construction
The legacy General Clad catalogue includes several CCS strand counts, conductivity classes and nominal sizes. A nominal area or a 7-wire / 19-wire description alone does not define the finished conductor.
State the individual wire diameter, number of wires, lay, actual metal cross-section, finished diameter and required material condition. Confirm resistance and mechanical performance for that construction rather than transferring values from single wire.
- Wire diameter, tolerance, strand count and lay
- Maximum DC resistance at a stated temperature and length
- Tensile or breaking-load requirements for the finished conductor
Match the conductor to the installation
Grounding and bonding projects also require fault current, clearing time, environmental conditions and connector qualification. Review the complete conductor and connection system against the project specification.
Historical EHS development is not a universal grade or railway approval. Identify any required high-strength condition and its acceptance criteria in the inquiry.
- Fault duty and relevant project requirements
- Connection method, corrosion exposure and inspection
- Drum length, packaging, handling and traceability
