Multipair Individually Screened Cables-Belden Equivalent 9777

This cable is commonly selected for:

• Professional 15-track audio, large-scale broadcast, stadium & music festival performance systems for ultra-long-distance high-fidelity low-crosstalk balanced audio transmission
• Industrial automation, PLC/DCS 15-loop high-density process control systems for ultra-long-distance reliable analog & digital control signal transmission
• Precision instrumentation, 15-channel test & measurement and high-speed DAQ systems for low-attenuation weak signal transmission
• Large industrial park & commercial complex intelligent building, integrated security and fire alarm linkage systems for multi-channel long-distance control wiring
• Telecommunications base station supporting systems, large industrial equipment internal wiring and cabinet interconnection in high EMI environments

Structural Design & Signal Benefits

• 18 AWG stranded (19×30) tinned copper conductors
• High-performance polypropylene insulation
• 15 twisted pairs with 100% coverage individual shielding
• Dedicated 20 AWG stranded tinned copper drain wire per pair

Installation & Performance Considerations

Installation Notes: Complete pair-by-pair pre-deployment inspection; comply with flex radius limits (10×OD static, 15×OD dynamic); do not exceed 1200N maximum pulling tension; maintain 30cm minimum separation from high-power cables; terminate 15 pairs one-to-one, use single-point grounding for each drain wire separately; indoor use only within -20℃~+80℃.

Performance Notes: Operate within 300V rated voltage and 18 AWG conductor ampacity; calibrate transmission distance to signal type; ensure consistent impedance matching for all 15 loops; maintain shielding and grounding integrity; avoid extreme high-noise environments to preserve long-term stable performance.
