Caledonian FIREGUARD Cables
FIREGUARD cables are constructed in the following typical design:
1. Solid/stranded annealed copper conductor
2. Glass mica tape/silicone rubber as flame barrier
3. XLPE/PVC as insulation
4. Normal or Flame retardant FRPVC as sheath
FIREGUARD cables are offered in either single core, multicore or multi-pair constructions.
The insulation material is usually PVC with different levels of fire retardance properties to meet different stringent environment requirement. The cables may be armoured or braided, with or without metallic screen, depending on different applications.
The FIREGUARD cables manufactured by Caledonian comply with either one or combination of the following standards.
Fire Retardant PVC Sheathed Cables (FIREGUARD)
Flame Retardant Power & Control Cables
XLPE Insulated, PVC Sheathed Power Cables (Multicore)
The cables are mainly used in power stations, mass transit underground passenger systems,
airports, petrochemical plants, hotels, hospitals, and high-rise buildings.
Basic design adapted to IEC 60502-1
Conductor: Plain annealed copper wire, stranded according to IEC(EN) 60228 class 2.
Insulation: Extruded cross-linked XLPE compound.
Filler, binder (if any): PP, PET
Outer Sheath: Thermoplastic PVC compound. UV resistance, hydrocarbon resistance, oil resistance,
anti rodent and anti termite properties can be offered as option. Compliance to fire performance
standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the
PVC compound and the overall cable design. LSPVC can also be provided upon request.
Physical AND THERMAL PROPERTIES
Temperature range during operation: Max.90°C for XLPE
250°C in short-circuit for 5secs max.
