KRONE Blown Fibre Tubes External - Direct Burial
The direct bury cable is a heavier construction than the direct install. This cable type lies flatter in trenches, has increased crush rating and has more resistance to localised bending. The assembly of 5mm tubes is surrounded by an aluminium moisture barrier and two polyethylene sheath layers for improved physical robustness. • Rapid, dedicated customer connections using proven mechanical protection of HDPE (High Density Polyethylene) • Low friction internal coating for maximum fibre blowing distance • Each tube accommodates one blown fibre unit (up to 12 fibres in a unit) • External tube cables available in 2, 4, 7 and 12 way assemblies • Cable construction - direct bury with aluminium moisture barrier • 5mm tube construction
