Instrumentation cables manufactured in accordance with British Standard BS5308
Whilst this British Standard was superseded by the Harmonised Standard BS EN 50288-7 in 2005 it is still widely referred to because the Harmonised Standard does not account for the higher voltage ratings and cable dimensions. A publicly available version of the Standard was published as PAS5308 in 2009.
British Standard BS5308 covers specifications for a range of instrumentation cables which we supply. These are available in a multitude of variants including Polyethylene (PE), Polyvinyl Chloride (PVC), Cross-Linked Polyethylene (XLPE), and Low Smoke Zero Halogen (LSZH) insulation materials, and armoured instrumentation cables.
BS5308 Part 1 Type 1 - Unarmoured - collectively screened (CAM) and individually & collectively screened (IAM/CAM or ICAT). PE insulated and PVC oversheathed.
BS5308 Part 1 Type 2 - Armoured - collectively screened and also individually & collectively screened. PE insulated, PE bedded, single wire armoured (SWA) and PVC oversheathed.
BS5308 Part 1 Type 3 - Armoured - collectively screened or individually & collectively screened. PE insulated, PVC bedded, lead alloy oversheath, single wire armoured and PVC oversheathed.
BS5308 Part 2 - PVC insulated instrumentation cables - British Standard BS5308 Part 2 specifies requirements for PVC insulated cables, in multicore and multi-pair construction, with or without screens. It provides the option to incorporate a single wire armour. Part 2 is further categorised as Types 1 & 2.
BS5308 Part 2 Type 1 - Unarmoured construction - PVC insulated and PVC oversheathed.
BS5308 Part 2 Type 2 - Armoured construction - PVC insulated, PVC bedded, single wire armoured and PVC oversheathed.
