Steel messenger strand consists of six wires wrapped around a center wire. The most common variety is carbon steel with a zinc coating. The zinc coating provides cathodic protection (CP) to the steel, meaning that red rust is prevented even on the cut ends. When comes to the sag of the aerial fiber optic cable, the elongation during the. Our specifications include ASTM 475, which covers metallic-coated steel wire strands, and ASTM A228 (music wire) for optical cables. Our messenger wire adheres to specifications set by ASTM International, a global. ADSS (All-Dielectric Self-Supporting) — a standalone, nonconductive jacketed cable that carries its own weight between poles without a supporting steel strand. ADSS is used where electrical isolation is needed (near power lines) because it has no metallic messenger. Installation requires attention. The telecom industry uses stainless steel lashing wire to secure or lash the messenger strand and fiber optic cable together.
