Description:Single core and multi-core cables with copper or aluminium conductor;XLPE insulated and PVC sheathed. Cables are rates at 0.6/1KV and conform to IEC 60502.
Construction:
 
Conductor:Plain annealed copper or aluminium conductor
Shape: Circular Compacted or shaped Stranded Conductor (Class 2)
Insulation:VV/VV22  PVC 
                  YJV/YJV22  XLPE (cross-linked polyethylene) rated at 90ºC
Colours for core indentification:
Single core-natural(black on request)
Two core-red,black
Three core-red, yellow,blue and black
Five core-red,yellow,blue,black and green/yellow
Armour:Galvanized steel wire armoured(SWA) or steel tape armoured(STA).
Sheath:PVC type ST2 to IEC 60502,colour black
Assembly:Two,three,four or five insulated conductors are laid up together if necessary filled with non-hygroscopic material compatible with the insulation.The filling may be omitted provided the outer shape of the cables remains practically circular and no adhesion occurs between cores and sheath.
Application: 
Suitable for use in power distribution lines or fixed installations with rated voltage up to 0.6/1KV indoor or outdoor,enclosed in conduit, in underground duct where not subject to mechanical damage.
Non-armoured cables are designated for general use including underground bruial,where they are not likely to suffer mechanical damage.
Armoured cables are most suitable for underground burial where there is a risk of mechanical damage.

Istallation:
In air
1.As the single core cable laying in parallel,the distance between the cables center is 2 times of the cable diameter,which cross sectional area of conductor<=182mm and 90mm,which cross sectional area of conductor>=240mm
2.Ambient temperature:40ºC
3.Max.Temperature of conductor:90ºC
4.Rating factors of current for ambient temperature.

Direct in ground
1.When the single core cable are installed separately,the distance between the cable’s center is 2 times of the cable diameter.
2.Ambient temperature:25ºC
3.Max. Temperature of conductor:90ºC
4.Soil therm our resistively:1ºC.m/W
5.Depth of laying:0.7m
6.Rating factors of current rating for ambient temperature.
