Instrumentation Cables, Application : Home, Industrial

standard : ( bs 5308 part I & part ii)

conductor : (is 8130)

high conductivity electrolytic grade annealed bare/tinned copper. Solid / stranded/ multi stranded conductor.

insulation : (is 5831) : type a, b, & c

general purpose pvc (poly vinyl chloride) hr/ fr/ lszh/ pe compound, or as per customer specification.

colour coding : (pair/triad/quad)

either colour coded or number printed , coloured ring marked or as per customer requirement.

laying of pair/ triad /quad :

pair/ triad/quad are laid up with suitable lay. Polyester film / melenex tape is provided to bind up laid up pair / triad / quad.

shielding /screening :

shielding/screening of thin layer of alluminum foil bonded to polyester film / tape with annealed tinned copper drain wire is installed to provide continuous contact with the shield/screen and allow to connection to ground. Tinning the drain wire reduces galvanic corrosion between drain and the shield / screen.

armouring is applied over inner sheath, it may consist of galvanized round steel wire or galvanized flat steel strips.

outer sheath : (is 5831) : type “ c” (pvc) or type st -1 or st-2 ( hr / frls)

outer sheth is applied over armouring in case of armoured cables or over inner sheath , in case of unarmoured cables. The colour of outer sheaths is generally black/ blue/ red/ gray. The sheath material may be general purpose pvc/hr/ frls/lszh compound .

application :

data transmission, process control systems, communications systems etc.
