Caledonian FIREGUARD Cables
CABLE CONSTRUCTION
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.
INTERNATIONAL STANDARD
The FIREGUARD cables manufactured by Caledonian comply with either one or combination of the following standards.
IEC 60332-1
IEC 60332-3C

PRODUCTS
Fire Retardant PVC Sheathed Cables (FIREGUARD)
Flame Retardant Optic Fiber Cables
Tight Buffered Distribution Fiber Optic cables
APPLICATION
This cables are used for interconnection of distribution boxes and end devices, where continued
functionality is required during a fire situation. The cables are very suitable for various indoor and
outdoor applications, including routing between buildings within ducts and inside building up to riser
shafts.
STANDARDS
Basic design adapted to Telcordia GR409-CORE / TIA/EIA 568B.3 / ICEA-S-83-596
CABLE CONSTRUCTION
Optical fibers: Singlemode and multimode tight fibers, with tight buffer coating.
Reinforcement: Either aramid yarn or fiber glass is wound around the tube to provide physical
protection and tensile strength, with added fire protection.
Inner Sheath(optional): Thermoplastic PVC compound type LTS3 as per BS 7655-6.1
Ripcord(optional): An optional ripcord can be located under the outer sheath to facilitate jacket
removal.
Armouring(optional):
STA: Corrugated steel tape armour
SWB: Steel wire braid
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 (fixed state): -20°C - +60°C
Temperature range during installation (mobile state): 0°C - +50°C
Minimum bending radius: 10 times the outer diameter for unarmoured cables
20 times the outer diameter for armoured cables
