Low voltage Aerial bundled cables
AL \ XLPE
Low voltage Aerial bundled cables are a set of insulated wires that are stranded and used to distribute household electricity.
The conductor of these cables is made of aluminum and the insulation used in them is made of XLPE type TIX 5, which is suitable for environmental conditions.
XLPE also means crosslink polyethylene insulation, which is made of resistant carbon against the sun's UV rays.
The number of strands (cores) of Aerial Bundled cable is determined according to the number of phases used (three-phase or single-phase), if the cable is three-phase, the number of strands is 5 or 6.
In the structure of 5-cores 3-phase cables, a stranded alloy conductor is used as the null-holder.
The rest of the cores (strands) are in the form of 3-phases and a lighting filament.
In the structure of 6-cores cables, a galvanized stranded conductor is used as a holder. This core only has the task of holding the rest of the cores around its axis. 3 cores of phase wire along with a core of neutral(null) wire and a core of lighting wire are other components of the cable.
In single-phase cases, two cores of cable cores is also reduced, and the number of cores may be 3 (if you use aluminum alloy as null) or 4 (if you use, galvanized core as holder).
Also, according to the diagnosis of experts in the electricity distribution industry in some places that do not require lighting and it is possible to remove the lighting core in all the above structures.
The national standard for the production of these cables is Tavanir instructions for production, and the international standards include HD 626 S1, NF C 33-209, AS / NZS 3560-1.
