Cable Tray Use (UL) Telephone Central Office Power Cable | Halogen-Free | UV & Fire-Resistant

Cable Tray Use (UL) Telephone Central Office Power Cable | Halogen-Free | UV & Fire-Resistant

Product Overview

The UL-Listed Telephone Central Office Power Cable is a specialized halogen-free cable designed for safe, reliable power distribution in telecom central offices and data centers. Featuring tin-plated copper conductors, halogen-free thermoplastic insulation, and UV-resistant sheath options, this cable complies with IEC 60332-3-24 fire performance standards and UL 1581 sunlight resistance requirements. Ideal for indoor cable tray installations, it ensures minimal smoke and toxic gas emissions during fires while supporting high tensile strength for demanding telecom environments.


Key Features

  • Halogen-Free Design: Reduces toxic fumes and corrosive gases in case of fire (IEC 60332-3-24 compliant).

  • UV-Resistant Sheath: Optional black UV-stabilized sheath (UL 1581) for outdoor-capable models (TFL492324/0, TFL492325/0, TFL492326/0).

  • High Tensile Strength: Withstands up to 4000N (unarmored) or 6000N (armored) during installation.

  • EMI Protection: AL/PET foil + tinned copper braid shielding for noise reduction (max. 5.09–8.21Ω/km resistance).

  • Flexible Installation: Cold-resistant down to -40°C and bending radii as low as 10x OD (unarmored).

Applications

This cable is engineered for:

  • Telecom Central Offices: Power distribution in cable trays for servers, switches, and routers.

  • Data Centers: Halogen-free backbone wiring for fire-safe environments.

  • Indoor/Outdoor Hybrid Use: UV-resistant models for rooftop or exposed telecom equipment.

  • Critical Infrastructure: Hospitals, airports, and government facilities requiring LSZH compliance.

  • High-Vibration Areas: Shielded design prevents EMI interference in dense equipment layouts.


Installation Guidelines

  • Bending Radius: Maintain ≥10x OD (unarmored) or 20x OD (armored) during routing.

  • Tensile Limits: Do not exceed 4000N (unarmored) or 6000N (armored) during pulling.

  • Temperature: Avoid installation below -40°C without pre-warming.

  • Grounding: Bond shields to ground per NEC/IEC standards for EMI mitigation.

  • Prohibited Uses: Not for direct burial unless armored and specified.


Why Choose This Cable?

  • Safety First: Halogen-free materials protect personnel and equipment during fires.

  • Durability: Tin-plated conductors resist corrosion; UV sheath extends outdoor lifespan.

  • Compliance: Meets global standards (UL, IEC) for telecom and data center projects.

  • Versatility: Suitable for indoor trays, outdoor UV-exposed routes (select models).

  • Future-Proof: Shields against EMI in high-density telecom environments.
