SINGLE CORE FIRE RESISTANT

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.

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

Conductors : Stranded Cl. 2 plain annealed copper
Insulation : Mica (fire resistant) tape covered by an extruded layer of cross – linked zero halogen, low smoke insulating compound
*Sheathed version also available.
Details available on request.

Circuit Integrity : 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
Acid Gas Emission : IEC 60754 – 1, BS EN 50267 – 2 – 1
Smoke Emission : IEC 61034, BS EN 50268
Flame Propagation : EN 60332 – 1, EN 60332 – 3, BS EN 50265, BS EN 50266

Kindly complete the part numbers for these cables by adding the suffix (in place of ‘xx’) for the insulation colour required :
01 – green, 02 – black, 03 – red, 04 – blue, 05 – yellow, 06 – green / yellow, 09 – brown, 12 – grey.

Current Carrying Capacity (Amperes).

Ambient temperature: 30°C. Conductor operating temperature: 90°C.

Notes:
1 Where a conductor operates at a temperature exceeding 70°C it must be ascertained that the equipment connected to the conductor is suitable for the conductor operating temperature (see Regulation 512.1.2).
2 Where cables in this table are connected to equipment or accessories designed to operate at a temperature not exceeding 70°C, the current ratings given in the equivalent table for 70°C thermoplastic insulated cables (Table 4DIA ) must be used (see also Regulation 523.1).
3 The above table is in accordance with Table 4E1A of the 17th Edition of IEE Wiring Regulations.

Voltage Drop (per ampere per meter).

Conductor Operating Temperature: 90°C.
r = Resistive Component.
x = Reactive Component.
z = Impedance Value.
*Spacings larger than those specified in Method 12 (see table 4A of the 17th Edition of IEE Wiring Regulations) will result in larger volt drop.
The above table is in accordance with Table 4E1B from the 17th Edition of IEE Wiring Regulations.
