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Whilst this British Standard was superseded by the Harmonised Standard BS EN 50288-7 in 2005 it is still widely referred to because the Harmonised Standard does not account for the higher voltage ratings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 signal 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).

BS5308 Part 1 - PE insulated instrumentation cables - British Standard BS5308 Part 1 specifies both the requirements and the dimensions of PE insulated cables in pairs with or without screen(s). It provides the option to incorporate a single wire armour or single wire armour with a lead sheath. Part 1 is further categorised as Types 1, 2 & 3.

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.
