ADSS cables are all-dielectric (non-metallic) and self-supporting, meaning they require no separate messenger wire or support strand. They are designed for aerial installation on utility poles or transmission towers.
The typical construction includes
✅ Loose tube design: Optical fibers are housed in water-blocked loose tubes (often filled with gel or waterproof compounds) for protection against moisture and mechanical stress.
✅ Strength members: Aramid yarns (e.g., Kevlar) or fiberglass reinforced plastic (FRP) are used for tensile strength.
✅ Jacket layers: Usually double-jacketed—inner polyethylene (PE) sheath and outer PE or (AT) sheath for higher voltage environments (e.g., >12 kV).
