All Dielectric Self-Supporting (ADSS) Cable
The all-dielectric self-supporting cable, often abbreviated as ADSS cable, is a type of stranded loose tube optical fiber cable that contains no conductive metal elements, and it is often used by electrical utility companies as a communication medium.
Structure
250μm fiber units are positioned in a loose buffer tube which is manufactured from high-modulus material and filled with water blocking compound, and then a certain amount of tubes and filler rods are stranded around a non-metallic central strength member, namely FRP (fiber reinforced plastic) strength member, thus creating the cable core. Then, the cable core is covered with PE inner sheath and aramid yarn, and finally a PE or AT (anti-tracking) outer sheath completes the entire structure.

Characteristic
1. Our self-supporting aerial cable is designed to be lightweight and small in diameter to reduce load on support towers and similar structures due to cable weight, wind and ice, and its maximum span length is over 1000m.
2. Thanks to the accurate excess fiber length and stranding pitch, this all-dielectric self-supporting cable exhibits excellent tensile strength and temperature stability.
3. This FRP reinforced ADSS cable has a service life of over 30 years, and AT sheath could be adopted to offer extraordinary anti-tracking performance.
4. The ADSS fiber optic cable could be laid without shutting off power.
