BS 6724 LSZH Armoured Cable – Fire-Safe Power for Demanding Installations

Cleveland Cable is the UK’s largest supplier of LSZH steel armoured (SWA) and aluminium wire armoured (AWA) cables. We offer a wide range of low-voltage (1kV) and medium-voltage (3.3kV) BS 6724 mains cables manufactured to British and IEC standards. These cables are ideal for industrial and commercial applications where fire safety, durability, and regulatory compliance are critical.

Applications: Reliable Power in High-Risk Environments

BS 6724 LSZH armoured cables are widely used in power and control circuits for fixed wiring installations. They can be clipped to surfaces, run on trays or ducting, and are robust enough for direct burial in free-draining soil or concrete. The galvanised armour provides excellent protection in environments where mechanical damage is risky.

Please note that these cables are not recommended for waterlogged ground or flood-prone areas.

Why Choose LSZH Over Traditional PVC?

BS 6724 Low Smoke Zero Halogen (LSZH) cables contain halogen-free compounds that reduce toxic emissions and smoke during fire. Unlike PVC alternatives, they emit less than 0.5% hydrogen chloride gas and only light grey smoke, helping to preserve visibility and reduce risk during emergency evacuations.

Key Benefits of BS 6724 LSZH Cables

• Ideal for public buildings such as airports, train stations, computer rooms, and data centres
• Emit less than 0.5% HCL gas, reducing risk to life and sensitive equipment
• Low smoke generation keeps signage and escape routes visible
• Fully compliant with BS 7671:2018 Regulation 422.2 on emergency evacuation safety

Are BS 6724 Cables Fire Resistant?

While BS 6724 LSZH cables are not classified as fireproof or equivalent to circuit integrity cables such as BS 7846 (30, 60, 120-minute ratings), they are considered fire-resistant due to their low fire load, limited smoke emissions, and reduced flame spread compared to PVC alternatives.
