The design institute responded that it was changed to ADSS fiber optic cable
All-dielectric self-supporting (ADSS) cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission lines and often sharing the same support structures as the electrical conductors. ADSS is an alternativ. Construction detailsNo metal wires are used in an ADSS cable. Optical fibers are either supported in loose buffer tubes, or arranged in a. Fittings used with ADSS cable may be tension type, used at dead-ends where the cable terminates or changes direction, or may be suspension type, only holding the weight of a span with tension transmitted through th. Cables must be designed for the worst-case combinations of temperature, ice load, and wind. An installed cable must not sag so low that it can be damaged by traffic under the line.
