Single core fire resistant cables are designed for installations in trunking and conduits where a fire situation may pose a major hazard. Circuit integrity is maintained and, for optimum performance, the cables should be installed in metal conduits. They have a stranded plain annealed copper class 2 conductor with mica (fire resistant) tape covered by an extruded layer of cross-linked low smoke zero halogen (LS0H) insulating compound. The insulation colour is selected through the 'xx' suffix of the part number, and a sheathed version is available on request.

Key features

• Circuit integrity for installation in metal conduits: BS 6387 categories C, W & Z
• Exceeds IEC 60331 - 3 hours at 750°C (950°C test equivalent to BS 6387 category C)
• Mica tape with cross-linked low smoke zero halogen (LS0H) insulation
• Voltage rating 450/750 V
• operating temperature -20°C to +90°C
• Sheathed version also available on request
• 8 insulation colours selectable via part number suffix (xx)

Applications

• Installations in trunking and conduits where a fire situation may pose a major hazard
