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