Insulated cables for overhead are mainly applied for conditions like roads and parkways in cities and towns, overhead lines near to buildings, construction sites, overhead lines between towers and poles,etc.
One widely applied series are referred to as Aerial Bunched Cable(ABC), which is usually grouped into two:
- Cables with supporting neutral core: the whole bundle is suspended and carried by the supporting core, whose conductor is usually AAAC or steel strand;
-Self-supporting bundled cable: suspension and carrying of the whole bundle is done by the phase cores.
Bundles can include one or more additional cores for public lighting and/or control purposes.
