Medium Voltage ABC Cable Construction
| Phase Conductor | Circular compacted stranded H68 aluminium to BS2627. |
|---|---|
| Conductor Screen | Extruded semi-conductive layer. |
| Insulation | XLPE. |
| Insulation Screen | Extruded semi-conductive layer. |
| Outer Sheath | HDPE. |
| Support Conductor | Aluminium alloy conductor (AAAC/1120). |
| Assembly | Three XLPE insulated cores are bundled around the AAAC/1120 support conductor in a right hand lay. |
Application:
Used for primary and secondary overhead distribution where limited space is available or desirable for rights of way.
Installed as an uninsulated conductor; however, covering is effective in preventing direct shorts and instantaneous flashovers should tree limbs or other objects contact conductors in such close proximity.
The resulting close-proximity configuration minimizes the amount of space and hardware required for line installation; particularly useful in congested areas such as alleyways or tight corridors.
