Parts of LT Aerial Bunched Cable
- Messenger conductor
- Aluminium phase conductor
- Semi-conducting conductor screen
- XLPE insulation semi-conducting
- Insulation screen
- Copper tapee
- PVC outer sheath
Advantages of LT Aerial Bunched Cable
LT Aerial bunched cables are prefered where human safety is a major concern and spacing between conductor is not available. They are used for comparatively smaller distances. LT AB cables are heavy as they consists of more insulating layers and insulation thickness is more.
No seperate standard but generally as per IS : 7098-2
LT AB cables consists of phase conductors which are fully insulated and sheathed. It consists of semi-conducting conductor screen, XLPE insulation, semi-conducting insulation screen, metalic screen of copper tape and PVC or Polyethylene outer sheath.
LT Aerial bunched cables consists of AAAC or Galvanized steel messenger conductor around which the phase conductors are twisted.Messenger conductor carries the weight of entire AB cable.
