Conductors for Signal, Cable Strength and Screening
Choose by the conductor’s duty. Signal cables need frequency, resistance and termination details. Strength-sensitive designs also need tensile load and span. Screening and grounding projects need the specified construction and fault-current or system requirements. Include the cable standard and installation environment with your inquiry.

Choose by conductor duty
Scroll horizontally to read all columns. Keep the conditions and units with each value.
| Duty | Materials and forms | Inputs that determine the choice |
|---|---|---|
| Signal conductor | Copper, CCA or CCS round wire | Frequency, impedance or attenuation, DC resistance and termination |
| Strength-bearing conductor | CCS round or stranded wire | Span, tensile load, strand construction and resistance |
| Screen or grounding conductor | Specified wire or strand construction | Fault-current duty, connection design, corrosion conditions and cable/system standard |
Compare the complete cable
CCA and CCS have different core metals and electrical/mechanical behavior. Compare the defined grade and construction; a copper surface does not make either a universal copper replacement.
