Flexible conductors with a defined construction
Strands & ropes
Bunches, concentric and compact strands, and highly flexible ropes with or without overall braids. The construction depends on flexibility, installation space and mechanical stress.

Ropes with overall braids
Ropes with vibration-damping overall braids for moving connections and mechanically stressed applications.
- Materials
- Cu-ETP1, Cu-OF1 and Histral® alloys
- Single-wire diameter
- Ø 0.05–0.10 mm; larger diameters on request
- Cross-section
- 0.35–120 mm²; larger cross-sections on request
- Surface finishes
- Bare, tin-plated, nickel-plated or silver-plated
- Condition
- Hard or soft annealed
- High flexibility and mechanical load capacity.
- The overall braid prevents the rope from unravelling and dampens vibration.
High-frequency strands
Strands made from multi wires, with surface finishes and lay lengths tailored to transmission requirements.
- Construction
- Strands made from multi wires, also with varying lay lengths
- Surface finishes
- High-conductivity plating or very smooth compacting where required
- Monitoring
