Parts of HT AB Cable
- Messenger conductor
- Aluminium phase conductor
- Semi-conducting conductor screen
- XLPE insulation semi-conducting
- Insulation screen
- Copper tapee
- PVC outer sheath
Advantages of HT Aerial Bunched Cable
Aerial bunched cables are heavy as they consists of more insulating layers and insulation thickness is more. Additionally each core has a metallic layer and an outer sheath. They have much higher overall diameter compared to MVCC
HT AB Cables having a rating of above 3300 V (33kV)
Aerial bunched 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.
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.
