- Instrumentation cables are used in data processing and process control and are suitable for installations in open spaces and for underground laying. For digital signals and solenoids , overall screened type and for analogue signals between junction boxes and electrical room/control building , individual and overall screened type may be applied.
- The overall screening of the pairs/cores protect it against outer electrostatic interference fields.
- Armoured types would be able to bear external mechanical forces.
In the voltage designation of U0/U(Um) , the rated voltages of the cables considered in this standard are as follows: U0/U(Um)=300/500(600) V a.c. U0 is the rated power frequency voltage between conductor and earth or metallic covering. Construction features: - Size : Up to 2.5 sq.mm - No. of cores/Pairs : Up to 61 cores and up to 50 pairs -Conductor material : Plain or tinned copper -Conductor type : Solid (Class1)/Stranded(class2)/Fine stranded (Class 5) - Round -Insulation: Cross-linked polyethylene (XLPE) , polyethylene (PE) or Polyvinyl chloride ( PVC) -Collective screen : Laminated screening tape comprise of aluminum bonded to polyester plus one or more tinned annealed copper wires applied over the screened pairs or laid up cores. -Inner sheath: Polyvinyl chloride (PVC) or polyethylene ( PE) -Armour: Galvanized steel wire, tape or braided armour -Sheath: Polyvinyl chloride (PVC) or Polyethylene (PE) Other features : -Ultra violet (UV) resistant colored outer sheath -Low smoke and fume (LSF) -Halogen free and flame retardant (HFFR) - Oil & hydrocarbon resistant -Fire resistant -Vermin proof Standards : PAS 5308 , BS 5308 Note : Insulated communication wire can be applied on request.
U is the rated power frequency voltage between conductors.
Um is the maximum value of the "highest system voltage" for which the equipment may be used.
