Belden 4300ULW Series Multi-Core Microphone & Instrument Cable, 500m Cable Length, Grey Jacket - 4300ULW.00500
This multi-core microphone & instrument cable is designed for audio signal transmission in professional and industrial settings where low-emission materials are required. It is a two-core unscreened cable with stranded conductors suitable for fixed installations and long-run reels in controlled-temperature environments.
Features and Benefits:
• 18AWG stranded conductor delivers flexible conductivity for frequent handling
• Bare copper conductors provide optimal electrical continuity for signals
• Low Smoke Zero Halogen jacket reduces toxic emissions during combustion
• Rated for 30V enabling safe use in low-voltage audio circuits
• Operates between -20°C and 70°C for typical indoor and stage environments
• Bare copper conductors provide optimal electrical continuity for signals
• Low Smoke Zero Halogen jacket reduces toxic emissions during combustion
• Rated for 30V enabling safe use in low-voltage audio circuits
• Operates between -20°C and 70°C for typical indoor and stage environments
Applications
• Suitable for permanent wiring of stage microphone lines
• Ideal for instrument cabling in theatre and broadcast installations
• Used with long-run audio feeds on 500m reels for venue distribution
• Can be used for routing signal between mixing desks and stage boxes

What conductor configuration is used to maintain flexibility?
Each core comprises seven-strand conductors that enhance bendability while preserving conductor cross-section.
How does the cable’s sheath behave in restricted-ventilation incidents?
The jacket is Low Smoke Zero Halogen which minimises smoke density and acidic gas output during thermal decomposition.
Is the cable suitable for screened audio applications?
No, it is manufactured as an unscreened multi-core cable and therefore does not include an overall or individual screening layer.
What approvals indicate compatibility with fire-performance requirements?
The construction meets recognised fire-behaviour standards for single-cable vertical flame spread and related smoke and corrosivity tests.
