Copper-Clad Steel: Strength, Resistance and Use FAQ
What is Copper Clad Steel?
steel core with metallurgically bonded copper cladding.
Copper-clad steel has a steel core and a bonded copper outer layer. A grounding inquiry needs fault duty, installation conditions and connection details; a coaxial-wire inquiry needs frequency, dimensions and electrical requirements. State the use before selecting a grade.
Primary Applications
- grounding
- coaxial cable cores
- messenger wire
- infrastructure conductors
Critical RFQ Specifications
- conductivity grade
- diameter
- tensile strength
- copper thickness
- elongation
- surface finish
Selection
What inputs are needed for grounding evaluation?
Provide the project-approved material requirements, fault current and duration, installation loads, soil or exposure conditions and connection details. A CCS material name does not determine the grounding conductor size or establish project acceptance.
Specifications
Which electrical and mechanical quantities should be compared?
State material conductivity at a defined temperature separately from finished-conductor resistance. Specify tensile strength or breaking load for the identified specimen, grade and condition; geometry and strand construction affect finished-conductor results.
Testing
How should copper-layer continuity be checked?
Agree cross-section measurements, surface inspection and applicable bend or torsion checks for the form. Inspect cut ends, formed areas and joints against the exposure requirements.
