Caledonian FIRETOX Cables
CABLE CONSTRUCTION
FIRETOX cables are constructed in the following typical design:
1. Solid/stranded annealed copper conductor
2. XLPE/LSZH as insulation
4. LSZH/flame retardant LSFROH as sheath
FIRETOX cables are offered in either single core, multicore or multi-pair constructions.
The insulation material can be thermosetting (XLPE, LSZH) or thermoplastic (EVA, LSZH) 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 FIRETOX cables manufactured by Caledonian comply with either one or combination of the following standards.
IEC 60332-1
IEC 60332-3C
IEC 61034-1/2
IEC 60754-1

PRODUCTS
Fire Retardant PVC Sheathed Cables (FIRETOX)
Flame Retardant Optic Fiber Cables
Flame Retardant Central Loose Tube Fiber Optic cables
Application
These cables are characterized by light weight and small diameter, suitable for both aerial and duct
installation. They are mainly installed inside buildings, tunnels,subways or closed areas in general,
specially designed to guarantee the signal transmission even in case of fire. The cable can also be
used for direct burial for armoured version.
STANDARDS
Basic design adapted to Telcordia GR-20 / RUS 7 CFR 1755.900 (REA PE-90) / ICEA S 87-640
CABLE CONSTRUCTION
Fibers: Singlemode and multimode fibers, with loose tube technology.
Structure: Central loose tube cable contains one tube with 2-24 single or multimode fibers, which
are filled with water blocking gel.
Water blocking: The jelly filled tube is waterblocked by using swellable tape and thread.
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): The cable can be jacketed with either PE or thermoplastic LSZH inner
sheath. PE is the preferred option in outdoor environment for water protection purpose.
Moisture Barrier Tape (optional): An aluminum moisture tape can be incorporated under the sheath
for water blocking and shielding purpose.
Armouring(optional):
For diect burial, either galvanized steel wire braid, corrugated steel tape armour or galvanized
steel wire armour is applied over an inner polyethylene or LSZH sheath. For steel tape armour, the
0.15mm thick steel tape is coated with a copolymer and applied with an overlap. For steel wire braid
or armour, single layer of galvanized steel wire braid or armour is applied.
Ripcord (optional): An optional ripcord can be located under the jacket to facilitate jacket removal.
Outer Sheath: Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1(Thermosetting
LSZH compound type SW2-SW4 as per BS 7655-2.6 can be offered.). UV resistance, hydrocarbon
resistance, oil resistance, anti rodent and anti termite properties can be offered as option.
