BS 6724 LSZH 0.6/1kV cable is a low-smoke, halogen-free, flame-retardant power and control cable designed for fixed installation environments where fire safety, smoke emissions, and toxic gas emissions must be minimized. Manufactured to BS 6724 and BASEC certification standards, this cable is widely used in commercial, industrial, and public buildings requiring enhanced fire resistance and reliable electrical performance.
LSZH 0.6/1kV Cable Structure
Conductor: formed to Class 2 stranded construction
- Excellent electrical conductivity
- Reduced DC resistance
- Improved flexibility for installation in fixed systems
- Stable current-carrying performance under continuous load
Insulation: XLPE (Cross-Linked Polyethylene)
- XLPE ensures that the conductor remains electrically isolated even in demanding industrial environments.
Bedding Layer: LSZH Compound
- A mechanical separator between armour wires and insulation
- A cushion that absorbs mechanical stress and prevents armour penetration
Armour Layer:
- Aluminium Wire Armour (AWA) for single-core cables
- Steel Wire Armour (SWA) for multi-core versions
