SINGLE CORE FIRE RESISTANT

thumbnail

Application

These cables are designed for installations in trunking and conduits where a fire situation may pose a major hazard. Circuit integrity is maintained and to achieve optimum performance such cables should be installed in metal conduits.

Standard

Adapted to EN 50525-3-41

Technical Data

Voltage Rating : 450 / 750 V

Operating Temperature : -20°C to + 90°C (the cable should not be flexed when the temperature is below 0°C)

Minimum Bending Radius : 8 x Overall diameter

Cable Construction

Construction : Stranded plain annealed copper conductor to BS EN 60228, class 2.

Insulation : Mica (fire resistant) tape covered by an extruded layer of cross - linked low smoke zero halogen (LS0H), insulating compound

*Sheathed version also available. Details available on request.

Circuit Integrity for installation in metal conduits : BS 6387 categories C, W & Z (when applied to a single cable) Exceeds IEC 60331 - 3 hours at 750°C - when the test temperature was increased to 950°C, equivalent to BS 6387 category C
