Detailed Description

BS 6724 is a British Standard flexible/Solid fire-resistant cable designed for control, instrumentation, and power circuits that require reliable operation during and after exposure to fire. It features copper conductors insulated with cross-linked polyethylene (XLPE) and a halogen-free, low-smoke fire-retardant outer sheath.

The cable is engineered to maintain circuit integrity in emergency situations, making it suitable for use in fire alarm systems, emergency lighting, evacuation systems, and other vital safety installations in buildings and infrastructure.

Key Features

• Copper conductor, flexible stranded (Class 5) or Solid copper

• XLPE insulation for excellent thermal and electrical performance

• Halogen-free, low smoke, fire-resistant outer sheath (usually black)

• Maintains circuit integrity during fire exposure (typically 90 or 120 minutes)

• Complies with British Standard BS 6724 and IEC 60331 standards

• Suitable for fixed installation in buildings, tunnels, and industrial plants

• RoHS-compliant and environmentally friendly materials
