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.
IEC 60332-1
IEC 60332-3C




Fire Retardant PVC Sheathed Cables (FIREGUARD)
Flame Retardant Instrumentation Cables
Individual and Overall Screened, Armoured Instrumentation Cables (Multipair)
The armoured PVC versions (Part 1 Type 2) are generally used when the risk of mechanical damage
is increased. The galvanized steel wire armour provides excellent protection. Generally used within
industrial process manufacturing plants for communication, data and voice transmission signals and
Basic design adapted to BS 5308 Part 1 Type 2
Conductor: Annealed or tinned copper, sizes: 0.5mm² and 0.75mm² mulitistranded(Class 5), 0.5
mm², 1.0 mm² solid(Class 1), 1.5mm² or 2.5mm², multistranded(Class 2) to BS6360
Insulation: XLPE (Cross Linked Polyethylene), or PE (optional)
Pairs: Two insulated conductors uniformly twisted together with a lay not exceeding 100mm
Individual Screen: Aluminium/polyester tape is applied over the laid up pairs metallic side down in
contact with tinned copper drain wire, 0.5mm²
Binder tape: PETP transparent tape
Overall Screen: Aluminium/polyester tape is applied over the laid up pairs metallic side down in
contact with tinned copper drain wire, 0.5mm²
Inner Sheath: PVC compound
Amouring: Galvanized steel wire armour
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.
Insulation Colour: See technical information
Outer Sheath: Black or blue
Maximum Operating temperature: -20˚C - + 90˚C( fixed installation)
0˚C - +50˚C(during operation)
Minimum bending radius: 6 x Overall Diameter
