BUFLEX® DGR Cable

Control and Power Reeling Cable

Control and Power Reeling Cables 0.6 / 1 (1.2) kV

Applications

Cables with reinforced polyurethan sheath, especially designed for reeling applications.
Due to high mechanical properties of PUR, Buflex cables could be used in hard conditions as quarries, mines …
