Why is fiber optic cable ADSS prone to leakage

ADSS fiber optic cables are prone to leakage primarily due to electrical corrosion, environmental exposure, and mechanical stress, which can compromise the cable sheath and core.Electrical CorrosionADSS cables are often installed on high-voltage transmission lines, exposing them to strong electric fields. The capacitive coupling between the cable, the conductor, and the ground creates a spatial potential. Moisture, dirt, or pollution on the cable surface allows a ground leakage current to flow, generating heat. This can form a "dry belt," and when the potential difference is high enough, an arc occurs, causing dry belt arcing. Over time, this arc can burn through the outer sheath and aramid yarn, eventually leading to cable fracture . Electrical corrosion is particularly severe in "three-span" locations, such as across highways or railways, where cable failure can have serious safety consequences .Environmental and Mechanical FactorsFiber optic cables are highly sensitive due to their thin glass cores. Environmental exposure, such as UV radiation, extreme temperatures, and moisture, can degrade the protective jacket, allowing water ingress. Water can freeze and expand, cracking the buffer tubes and core, which increases signal attenuation and can lead to complete signal loss . Mechanical stress, including bending beyond the minimum radius or excessive tension, can create microbends or macrobends in the fiber, causing light to leak from the core and reducing transmission efficiency .Combined EffectsThe combination of electrical, environmental, and mechanical stresses makes ADSS cables particularly vulnerable. Electrical leakage accelerates sheath degradation, while environmental factors like moisture and UV exposure weaken the cable structure. Mechanical stress from wind, ice, or improper installation further exacerbates the risk of leakage and eventual cable failure .Mitigation StrategiesTo reduce leakage risks, operators can:Use cables with higher-grade sheaths resistant to electrical corrosion.Apply water-blocking materials and UV-resistant jackets.Maintain proper tension and adhere to minimum bend radius guidelines.Conduct regular inspections, especially in high-risk spans, to detect early signs of corrosion or mechanical damage . By addressing these factors, the reliability of ADSS fiber optic cables can be significantly improved, minimizing leakage and service disruptions.

OverviewAccessories and installationConstruction detailsApplication issues

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 the next span of cable. Reinforcing rods are used at dead-ends and may sometimes be used on either side of a suspension support.
