Single Core Fire Resistant

RR Kabel

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 : -20OC to + 90OC (the cable should not be flexed when the temperature is below 0OC)
Minimum Bending Radius : 8 x Overall diameter

Cable Construction

Conductors : 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.

Properties

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
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

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.
