Low-Smoke Halogen-Free Sheath
LSZH materials help reduce smoke and halogen emission in enclosed or public installation areas.
LSZH Cable
LSZH Cable for low-smoke halogen-free building and infrastructure routes.
LSZH Cable supports projects requiring low-smoke halogen-free sheath materials for public buildings, transport or enclosed installations.
Product Overview
LSZH 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
- public buildings, transport facilities and enclosed electrical routes requiring low-smoke halogen-free materials
- commercial, infrastructure and indoor cable systems where smoke and halogen performance matter
- power, control or building cable routes requiring LSZH sheath or insulation review
- projects where fire-safety wording must separate LSZH from fire-resistant and flame-retardant claims
Construction
Conductor with LSZH insulation or sheath route according to the cable type and project standard. Smoke density, halogen-free material requirement and flame performance should be reviewed before final selection.
Marking on Cable
FARWALK CABLE – LSZH 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
Public Safety Route
Reviewed for buildings, tunnels, transport facilities and indoor systems where smoke control matters.
LSZH Standard Review
For LSZH Cable, BS 7211 or local LSZH requirements should be confirmed with project documents.
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.
