Fire-resistant cable is designed to maintain circuit integrity during a fire for a specified period, keeping critical systems energised. It typically uses copper conductors with a mineral or special insulating barrier, often with low-smoke, halogen-free materials. Performance is defined by fire-test standards.
| Property | Typical value |
|---|---|
| Conductor | Copper (solid or stranded) |
| Insulation | Mica/glass fire barrier with XLPE or LSZH; or mineral insulation (MI) |
| Voltage rating | Typically 300/500V or 450/750V; 0.6/1kV for power types |
| Common sizes | Typically 1.5–4 mm² for control/alarm; larger for power circuits |
| Cores | Single- or multi-core, often with earth conductor |
| Temperature rating | Insulation typically 90°C continuous; withstands high fire temperatures for a rated period |
| Standard | BS 6387, IEC 60331, BS 8434, or equivalent EN standards |
