- LV power cables for energy supply are used for industry and distribution boards , power stations , panels , house connecting boxes , subscriber networks & street lighting . those cables are installed in open air , underground , indoor and in cable ducts .
- 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 IEC standard are as follows: U0/U(Um)=0.6/1(1. 2) – 1.8/3(3.6) KV. Um is the maximum value of the "highest system voltage" for which the equipment may be used. Construction features: -Conductor size : Up to 630 sq.mm - No. of cores : 1 to 5 cores -Conductor material: Plain/Tinned copper or aluminum -Conductor type: Solid(Class1)/Stranded(class2)/Fine stranded (Class 5) - Shaped or round -Insulation: Cross-linked polyethylene (XLPE) or Polyvinyl chloride ( PVC) -Filler/Inner sheath: Polyvinyl chloride (PVC) -Metallic sheath : Lead sheath -Separation sheath: Polyvinyl chloride (PVC) or polyethylene ( PE) Multi core cables :Galvanized steel wire,tape or braided armour Single core cable :Aluminum wire or tape -Sheath: Polyvinyl chloride (PVC) or high density polyethylene ( HDPE) 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 : IEC60502-1,VDE0271,ISIRI3569-2 Note : Cables with rated voltage 1.8/3 (3.6) KV will be fabricated with one or three cores and have a metallic layer surrounding the cores either individually or collectively .
U0 is the rated power frequency voltage between conductor and earth or metallic screen.
U is the rated power frequency voltage between conductors.
