Armoured Cable LSZH – XLPE Insulated | TWI Wires & Cables
TWI Wires & Cables is a leading manufacturer and exporter of Low Smoke Zero Halogen (LSZH) Armoured Cables designed for installations where fire safety, low smoke emission, and minimal toxic gas release are critical.
Our LSZH armoured cables are engineered for public buildings, tunnels, railways, commercial infrastructure, oil & gas facilities, and power distribution projects across Africa and the Middle East.
Unlike conventional PVC cables, LSZH cables emit:
- Very low smoke
- No halogen gases
- Minimal toxic fumes
- Reduced acid gas emission
This makes them ideal for confined and high-occupancy environments.
Why Choose LSZH Armoured Cable?
During fire conditions, traditional PVC cables release dense black smoke and corrosive gases. LSZH cables are specially formulated to comply with stringent fire safety regulations.
LSZH Armoured Cables are commonly used in:
- Airports
- Hospitals
- Shopping malls
- Metro rail systems
- Tunnels
- Underground railway networks
- Marine installations
- Industrial plants
- Oil & gas facilities
