Power Cables for Overhead Lines

Cables for overhead installations may be used in different types of installations: On free hanging facades between posts; On fixed facades; Trees and poles. Interception of forest areas without the need of clearance and maintenance of openings is allowed.

-Cables with supporting zero conductor, the whole bundle is suspended and carried by the supporting conductor, which is made of aluminum compound.

- Self-supporting construction, suspension and carrying of the whole bundle is done by the phase insulated conductors.

Bundles can include one or two additional conductors for public lighting and control pair.

Product Description
Low Voltage Aerial Bundled Cable/ Low Voltage ABC Cable

The basic construction is as follows:
3 power cores consisting of standard aluminium conductors, insulated withXLPE insulation
+ One sheath lighting aluminium conductor with XLPE insulation(optional)
+ One messenger Al-alloy conductor (bare or covered)

The messenger conductor can be of galvanised steel wire also.
The purpose of messenger wire is
A) It acts as load bearing wire.
B) It acts as earth or neutral conductor.

To be used at cotages of 600V phase-to-phase or less and at conductor temperatures not to exceed 75oC for polyethylene insulated conductors or 90oC for crossliked polyethylene(XLPE) insulated conductors.
