All-dielectric self-supporting cable suspension type, only holding the weight of a span with tension transmitted through the next span of cable. Reinforcing rods are used on either side of a support and at dead-ends. Wind-induced aeolian vibration is a factor since ADSS cables have light weight, relatively high tension, and little self-damping. Anti-vibration dampers are installed on each span near the support points. Accessories must not be clamped directly to the cable but instead over reinforcing rods, to protect the cable from electrical and mechanical damage. Termination boxes are used to enclose and protect splices between the ADSS cable and "inside plant" cable
