Belden 70030 Series 2 Core Screened, 3.1 mm OD, 500 m, Black

This audio cable is designed for professional installations where screened conductors and reduced fire emissions are required. It uses stranded oxygen-free copper conductors with a protective conductive screen and a polyethylene outer sheath, intended for long runs supplied on a 500m reel. The construction prioritises low halogen content and minimised smoke output to reduce risk in enclosed spaces while maintaining signal continuity.

• Screened construction reduces external electromagnetic interference
• Oxygen-free copper stranded conductors improve signal transmission
• Low smoke zero halogen composition limits toxic emissions
• Polyethylene jacket provides mechanical robustness and abrasion resistance
• Two-core layout with seven strands per core supports flexible routing

• Suitable for permanent venue audio wiring installations
• Ideal for theatre and auditorium signal runs
• Used with fixed mixing desks and stage equipment cabling
• Can be used for multi-room distributed audio systems
• Appropriate for commercial building AV system deployments

Each core is formed from seven stranded conductors MADE from oxygen-free copper.

It is supplied wound on a 500m reel to facilitate long continuous runs.

The cable meets the IEC 60332-1-2 standard for flame propagation testing.

The conductive screen mitigates interference from adjacent power and signal sources.

The outer sheath is polyethylene, chosen for its durable, wear-resistant properties.
