Circuit Integrity Focus
Fire-resistant cable is used when circuits must continue operating for a specified time under fire conditions.
Fire Resistant Cable
Fire Resistant Cable for critical circuits requiring fire-resistance review.
Fire Resistant Cable is selected where circuit integrity under fire conditions and recognized fire-resistance test routes are part of the project requirement.
Product Overview
Fire Resistant Cable should be selected according to the actual project route, not by product name alone. Before quotation, review application environment, performance standard, construction route, installation condition and required project documents. Datasheet wording, compliance documents and final supply notes should stay aligned with the selected standard and installation conditions.
Applications
- emergency power and critical circuits requiring circuit integrity under fire conditions
- public buildings, transport facilities, tunnels and infrastructure electrical systems
- fire alarm, smoke control, emergency lighting or life-safety related routes where specified
- projects requiring IEC 60331, BS 6387 or equivalent fire-resistance documentation
Construction
Copper conductor with fire-resistance construction such as mica tape and suitable insulation/sheath system according to the required test route. Final design should be reviewed against IEC 60331, BS 6387 or project-specific circuit integrity requirements.
Marking on Cable
FARWALK CABLE – Fire Resistant Cable – [standard] – [voltage/rating] – [size] – [year] – [meter mark]
Cable Identification
- Cable identification, sheath color and core marking should follow the project application and standard route.
Standards
- IEC / BS / UL project standards
- application-specific technical requirements
Main Features
Emergency System Use
Suitable for fire alarms, emergency lighting, smoke control and critical building safety circuits.
Test Standard Alignment
For Fire Resistant Cable, IEC 60331, BS 6387 or local fire-performance requirements should be confirmed before quotation.
Product Selection Guide
Application First
Confirm whether the project requires fire survival, flame retardance, LSZH, submersible, EV, rail or composite cable.
Performance Test
Match IEC 60331, IEC 60332, BS 6387, BS 7211 or other requested tests to the actual project requirement.
Installation Environment
Review heat, water, smoke, oil, movement, vibration or public-safety conditions before choosing materials.
Document Requirement
Confirm datasheet, test report, sample, marking and packing requirements before quotation.
