RE-2X(st)HKHRH,RE-2Y(st)HKHRH
- Instrumentation cables are used in data processing and process control and are suitable for installations in open spaces and for underground laying and also in areas and applications where electrical integrity of the cable has to remain intact for at least three hours.. 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.
- Lead sheathed types are designed to be used in any applications where the cables may be subjected to solvent penetration or corrosive attack or hydrocarbons.
In the voltage designation of U0/U(Um) , the rated voltages of the cables considered in PAS 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. - 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 -Primary Insulation: Mica glass tape -Secondary Insulation: Cross-linked polyethylene (XLPE) 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 halogen free compound -Metallic sheath : Lead sheath -Separation sheath: Polyvinyl chloride (PVC) or halogen free compound -Armour: Galvanized steel wire, tape or braided armour -Outer sheath: Polyvinyl chloride (PVC) or halogen free compound
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 Standards : IEC60331 , PAS 5308 , BS 5308
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.
