These look like spiral wire wraps. They gently grip the cable over a long length (often 1 meter), distributing the tension evenly so the jacket isn't damaged. ADSS, short for All Dielectric Self-Supporting fiber optic cable, is a specialized aerial cable engineered to two non-negotiable requirements: All Dielectric: No metallic materials (e., steel wires, copper conductors) in its construction. It requires no messenger wire, withstands high electric fields up to 220 kV, and supports spans from 50 m to over 1,500 m — making it. 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. What is ADSS cable?If you drive down any rural highway or look up at high-voltage transmission towers, you will likely see a thick black cable hanging below the power lines. It uses aramid yarn strength members for tensile capacity and is available with PE (standard aerial) or AT (anti-tracking for power line).
