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
