Building Wire
Low-smoke halogen-free, XLPE and PVC insulation compounds with building-wire extrusion lines for safe, code-compliant installation cable.
What this application demands
Building and installation wire carries power through occupied spaces, so fire behaviour and durability matter as much as conductivity. LSZH supplies low-smoke halogen-free, cross-linked and PVC insulation compounds — plus the building-wire extrusion lines to run them — helping manufacturers produce installation cable that is safe in a fire and built to last.
Fire safety in occupied buildings
Cables in walls, risers and ceilings must limit smoke and avoid corrosive halogen gas so people can evacuate and equipment survives. LSZH and HFFR compounds address this directly.
Temperature and electrical rating
Installation wire typically runs 70–90 °C, with cross-linked grades available for higher-temperature or higher-reliability circuits and stable insulation resistance.
Mechanical durability
Wire is pulled through conduit and around corners during installation, so insulation needs good tensile strength, elongation and abrasion resistance.
Standards compliance
Flammability designs target FT2, VW-1 and IEC 60332 series requirements depending on the cable type and market.
Compounds for this application
HZD2720-L and XD2200 provide 125 °C low-smoke halogen-free insulation; HZDFR4100 is a thermoplastic LSZH sheathing compound supporting IEC 60332-3 bundled-burning designs.

Selection & structure
- Choose LSZH where smoke and halogen gas are restricted (public and high-occupancy buildings)
- Confirm temperature class and required flame standard (FT2 / VW-1 / IEC 60332)
- Balance insulation hardness and flexibility for the installation method
- Specify colour coding for phase / circuit identification
Why LSZH for this application
- Insulation and sheathing compounds with verified low-smoke, low-toxicity data
- Material and extrusion-line matching for consistent surface quality
