Instrumentation Cables BS EN 50288-7

INSTRUMENTATION CABLES BS EN 50288-7 (or BS EN 50288-7 as it is now known in the UK) is increasingly being specified. Unsurprisingly there are close similarities to the BS5308 standard (and indeed PAS5308, the Publicly Available Standard which is likely what many people now perhaps unwittingly reference). Yet there are subtle differences and new terminology to understand when referring to these cables.EN 50288 covers the following range of cables. These EN50288-7 cables are available in a number of variants according to their specific applications, with configurations including collectively screened multi-core or multi-pair, collectively and individually screened pairs in metal foil (PiMF) and collectively and individually screened triple in metal foil (TiMF). They are also available as collectively screened – collective aluminium mylar (CAM) or individually and collectively screened (ICAM).

Pair/Triad shielding option

Oiptionally ,Each pair or triad is shielded with aluminum mylar tape with a tinned copper drain wire for electrostatic shielding for analog applications.

Assembly

Several pairs/triads or shielded pairs/triads are assembed to for a cablke core and optionally shielded with a tinned copper drain wire to provide etectostatic shield.

Inner sheath option

For armored cables a flame retardant PVC inner jacket is extruded over the cable core under the armor.

Environmental protection

Lead sheath or a multilayer sheath AL/HDPE/PA in accordance with BS EN 50288-7 is avilable for direct burial application as a hydrocarbon protection.

Armor

Galvanized steel wire or galvanised steel wire braid or galvanised steel tape armor option is available
