Caledonian fireflix Cables
CABLE CONSTRUCTION
fireflix 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/silicone rubber as insulation
4. LSZH/Flame retardant RPVC as sheath
fireflix cables are offered in either single core, multicore or multi-pair constructions.
The insulation material can be elastomeric (EPR, SR), 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 fireflix cables manufactured by Caledonian comply with either one or combination of the following standards.
BS 6387
IEC 60331
IEC 60332-1
IEC 60332-3C
IEC 61034-1/2

Fire Resistant Fire Alarm Cables
225V SR Insulated & LSZH Sheathed Fire Alarm Cables
JE-H(St)H…Bd FE180 E30 (CU/SR/OSCR/LSZH 225V Class 1)
JE-H(St)HSWAH…Bd FE180 E30 (CU/SR/OSCR/LSZH/SWA/LSZH 225V Class 1)
APPLICATION
The cables are used for the internal wiring of building when the circuit integrity during fire is paramount. The cables are intended for use in fire fighting plants with special ceramized silicone insulation, with and without aluminum foil and LSZH outer sheath. The fire alarm cables with 30 to 90 minutes circuit integrity should be used for control voltages and data transfer in alarm and fire alarm systems, where a system circuit integrity E30/E60/E90 depending on lay system in accordance with DIN 4102-12 is required. The circuit integrity is guaranteed with a test voltage of 110V.

CABLE CONSTRUCTION
Conductors: Solid annealed bare or tinned copper sized 0.6/0.8/0.9mm as per class 1 of VDE 0295/IEC 60228.
Insulation: Silicone Rubber compound as per DIN VDE 0266.
Cabling Elements: Insulated cores are twisted to form pairs with varying lay length to minimize crosstalk. Two-pair cable had four cores laid in quad formation.
Cabling: Pairs are cabled together.In cables with 8 pairs or more, 4 pairs are assembled to form a bunch, and the bunches are then cabled together.
Cable Core Assembly: The twisted pairs are stranded to the core in layers.
Core Wrapping: One or more non hygroscopic polyester tapes are helically or longitudinally laid with an overlap prior to sheathing.
Screen: A laminated Aluminum/Polyester tape is placed in contact with solid copper 0.6mm or 0.8mm drain wire.
Inner Sheath(optional): PE or thermoplastic LSZH compound type.
Armour (optional): Either corrugated steel tape armour or galvanized steel wire is applied over an inner polyethylene sheath. For steel tape armour, the 0.15mm thick steel tape is coated with a copolymer and applied with an overlap. For steel wire armour, single layer of galvanized steel wire armour is applied.
Ripcord: Nylon ripcord may be placed parallel to the cores to facilitate sheath removal.
Drain Wire: A solid tinned earth/continuity wire shall be laid longitudinally for screened cables.
Outer Sheath: Thermoplastic LSZH compound HM2 as per DIN VDE 0207-24 .
