The Loose Tube Cable All Dielectric Self-Supporting (LTC ADSS) is a metalfree aerial distribution cable, with dry waterblocking and aramid yarns under the outersheath. This cable is to be used under all dielectric circumstances, for example on distribution and high voltage power lines, railway, tram, trolley bus lines and between buildings. Because of its strong tensile members it is suitable for aerial applications without using additional strenght members. This cable is designed for spans between approx. 250 and 450 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’.
