Aerial bundle cable: Cluster overhead lines are mostly manufactured in accordance with French standards, of course, they can also be manufactured in accordance with national standards. Now they are mainly used abroad.
High-voltage transmission is generally carried out underground in cities with insulated cables, and is often transmitted in the field by overhead lines carried by towers.
Application:
For urban and rural overhead secundary distribution networks, with voltages up to 1000 V.
Construction:
1. Conductor: Aluminium 1350, class 2.
2. Insulation: Cross linked polyethylene XLPE
3. Public lighting: Aluminium 1350 insulated with cross-linked polyethylene XLPE.
4. Insulated neutral messenger: AAAC - All Alloy Aluminium 6201 - XLPE.
Main characteristics:
Decreases energy theft, cross-linked polyethylene allows more current capacity and high insulation resistance, lower inductive reactance than with bare conductors, used in overhead distribution lines. Increased safety due to its mechanical strength and toughness of the insulation. Insulators are not necessary for installation. Resistance to abrasion, weather and sunlight.
