The Central Tube Cable All Dielectric Self Supporting Cable (CTC ADSS) is an aerial central tube cable with low bend radius, no waterpeak G.657.A1 fibres and dry-waterblocking aramid yarns underneath the polyethylene outer sheath. This FttX-cable is intended for use as an aerial customer drop cable. This cable is designed for spans between approx. 30 and 150 mtrs, depending on installing and surroundings conditions, with the conditions from the NESC tables as a basis. For further information, please consult document Sag & Tension Calculations under characteristic ‘Specification’.
