Aerial bundled medium voltage power cables with PE sheath - Applications 

These cables are suitable for medium voltage power distribution in distribution networks (6/10(12);12/20(24) kV).

They may be put on the overhead lines in old and residential areas.

Provides a shortcut to electrification without affecting the townscape and its environs.

These cables can be strung safely on the same poles with low-voltage and telecommunication cables and have water resistant properties.
