Fire Resistant / LSZH Power Cable

Fire Resistant / LSZH Power Cable

Fire Resistant / LSZH Power Cable for power power distribution and project cable selection.

 Fire Resistant / LSZH Power Cable is used where power cable routes require mechanical protection, buried installation review or stronger installation durability than unarmoured cable.

  • Key Technical Points:
  • Fire-resistant, flame-retardant and LSZH are different requirements and should be separated clearly.
  • Circuit integrity, smoke/halogen performance and flame spread level depend on the project fire route.
  • Conductor, insulation, mica tape or sheath construction should follow the requested test standard.
  • Datasheet and compliance wording should be reviewed against the building or infrastructure specification.
  • Product Overview

    Fire Resistant / LSZH Power Cable should be selected according to the actual project route, not by product name alone. Before quotation, review voltage class, conductor material, insulation system, armour or screen design, sheath route and installation condition. Datasheet wording, compliance documents and final supply notes should stay aligned with the selected standard and installation conditions.

    Applications

    • public buildings, transport facilities and infrastructure power circuits with fire-safety requirements
    • emergency power, fire alarm or critical circuit routes where project documents request fire performance
    • enclosed building cable routes requiring LSZH, flame-retardant or fire-resistant material review
    • fixed LV power distribution where compliance documentation is needed before project approval

    Construction

    Copper or aluminum conductor as specified; XLPE or PVC insulation according to voltage grade; optional armour and sheath according to installation condition; armour layer for mechanical protection; fire-resistant, flame-retardant or LSZH material route according to requirement. Final dimensions, electrical values and test requirements should follow the selected standard and project datasheet.

    Marking on Cable

    FARWALK CABLE – Fire Resistant / LSZH Power Cable – [standard] – [voltage] – [core x size] – [year] – [meter mark]

    Cable Identification

    • Core identification can follow color or number marking according to standard and project requirement.
    • Outer sheath color, voltage marking and meter marking can be reviewed before production.

    Standards

    • IEC 60502-1 / IEC 60502-2
    • GB/T 12706
    • BS / VDE / NFC routes where specified

    Main Features

    Fire-Performance Construction

    Cable materials are selected for flame retardant, fire-resistant or LSZH requirements according to the project route.

    Power Circuit Continuity Review

    Used where power distribution routes must consider smoke emission, flame spread or circuit integrity requirements.

    Document-Ready Selection

    For Fire Resistant / LSZH Power Cable, datasheets, test reports and compliance documents should be aligned with the specified fire-performance standard.

    Product Selection Guide

    Voltage Class

    Start with the rated voltage; LV, MV, HV and EHV cables use different standards, tests and construction logic.

    Installation Route

    Confirm tray, duct, direct burial, tunnel, outdoor, indoor or underwater-related conditions before selecting armour and sheath.

    Conductor / Core Choice

    Review copper or aluminum, single-core or multicore construction by current rating, voltage drop and installation layout.

    Fire / Mechanical Requirement

    Select LSZH, fire-resistant, armoured, water-blocking or special sheath options only when the route requires them.
