Mineral Insulated Construction
Mineral insulation and metal sheath support high fire-performance and high-temperature cable routes.
Mineral Insulated Cable
Mineral Insulated Cable for mineral insulated fire-survival and high-temperature routes.
Mineral Insulated Cable is used for high fire-performance and high-temperature routes where mineral insulation construction is specified.
Product Overview
Mineral Insulated 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
- critical fire-safety circuits requiring mineral insulated cable construction
- high-temperature or fire-survival routes in buildings, tunnels and industrial facilities
- emergency power, alarm or life-safety systems where MI cable is specified
- projects requiring construction, termination and installation method confirmation
Construction
Mineral insulated cable construction with metallic sheath and mineral insulation according to the specified high-temperature or fire-survival route. Termination, bending and accessory requirements should be reviewed before quotation.
Marking on Cable
FARWALK CABLE – Mineral Insulated 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
Critical Circuit Use
Used where fire survival, compact construction or high-temperature performance is specified.
Termination and Route Review
For Mineral Insulated Cable, cable size, sheath material, termination method and installation environment should be confirmed together.
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.
