Assembly
Insulated conductors are laid up together, if necessary interstices may be filled with fillers.
Fillers
Non-hygroscopic Poly propylene fillers are included between laid up cores wherever required.
A separator tape of non-hygroscopic poly propylene material is applied over laid up cores wherever necessary.
Bedding
Bedding Extruded PVC compatible with operating temperature.
Armour
For Single Core - Aluminium round wire / flat Strep.
For Multicore - Galvanised Steel round wire / flat wire / tape. .
Outer Sheath
Extruded PVC / Special PVC compound such as Flame Retardant (FR), Flame Retardant Low Smoke (FRLS), Low Smoke Zero Halogen (LSOH) can be used for outer sheath to suit a variety of environment and fire risk conditions. Flamabillity test confirms to IEC 332 & Swidish chimeny. For installation where fire and associated problems such as emission of smoke and toxic fumes offer a serious potential threat, special LSF (Low smoke & fumes) compound can be provided. LSF compound is Halogen free (Flourine, Chlorine, Bromine) when tested as per BS 6425 (Pt 1) & IEC 60754 (Pt 1). The acid gas evolved during combustion is less than 0.5% by weight of material.
Minimum Bending Radius
12 times the cable diameter
Admissible Pulling Force
Aluminium-30/mm
