BS7846 Cable

British Standard BS7846 compliant cables are fire resistant mains cables used for fixed installations, particularly in applications where maintaining circuit integrity during a fire is critical, such as in fire alarm systems, emergency lighting, and power circuits.

BS7846 cables come armoured with SWA (Steel Wire Armour) to increase resistance to mechanical stress. They also feature a LSZH (Low Smoke Zero Halogen) sheath to reduce smoke and gas emissions under fire conditions, and MGT (Mica Glass Tape) separators to ensure circuit integrity for the rated time period, these cables are typically used in emergency lighting and fire detection and alarm systems that must remain operational under the harshest of conditions.

BS7846 cables are commonly used in

Fire alarm systems: Ensuring the continued operation of fire detection and alarm systems during a fire.
Emergency lighting: Maintaining illumination for safe evacuation during a fire.
Power circuits: Providing a reliable power supply to essential equipment in fire-prone environments.
Public buildings and infrastructure: Including hospitals, tunnels, and transportation systems where fire safety is paramount.
