ADSS Fiber Optic Cable High Tension Line Use

ADSS (All-Dielectric Self-Supporting) fiber optic cable for high tension lines is a fully dielectric self-supporting optical cable specially designed for overhead laying on high-voltage power transmission lines, which is a key supporting product for the integration of power communication and smart grid construction. Different from traditional metal-containing optical cables, ADSS optical cable adopts an all-dielectric structure with no metal components inside, which completely avoids electromagnetic induction, corona discharge and signal interference problems caused by high-voltage electric fields. It can operate stably in the strong electromagnetic interference environment of high-tension line corridors for a long time, and will not cause any impact on the normal operation of power transmission lines, solving the technical bottleneck of communication wiring in high-voltage power scenarios.

In terms of mechanical performance, high-tension ADSS optical cable has ultra-high tensile strength and structural stability, customized for different voltage levels of high-voltage lines (10kV to 500kV). It adopts multi-layer reinforced structural design, with high-strength aramid fiber as the main tensile bearing component, which can withstand huge axial tension and lateral wind load during long-span overhead laying. The outer sheath uses special anti-electric-corrosion and weather-resistant materials, which can resist electric corrosion, ultraviolet radiation, high and low temperature alternation and harsh outdoor weather conditions in high-voltage electric field environments, effectively preventing cable aging, cracking and performance attenuation, and ensuring a service life of more than 20 years.

This type of ADSS optical cable is mainly used for communication networking of high-voltage power transmission lines, including smart grid power dispatching communication, power monitoring data transmission, power equipment remote signal transmission, and auxiliary communication network construction of power systems. It realizes the integration of power line and communication line laying, saves corridor resources, and improves the integration level of power and communication infrastructure. Its all-dielectric safety structure, strong anti-interference ability and excellent long-span laying performance make it the only dedicated optical cable for high-tension line communication laying, providing stable and reliable optical transmission guarantee for the safe operation and intelligent upgrading of modern power grids.
