> High-frequency CCS conductors for RF and coaxial applications

## Overview

At frequencies above 1 MHz, current travels predominantly on the conductor surface via the skin effect — making CCS the ideal material for RF applications. The copper cladding carries the signal while the steel core provides strength and cost savings.

## Benefits

- **Skin Effect Optimization**: Above 5 MHz, >95% of current flows within the copper cladding layer — making CCS electrically identical to solid copper for RF.
- **Silver-Plated CCS**: For frequencies above 100 MHz, silver-plated CCS maximizes surface conductivity while maintaining steel-core mechanical advantages.
- **Impedance Control**: Tight diameter tolerance (±0.003mm) enables precise impedance control in coaxial and twin-axial cable designs.
