ADSS Fiber Optical Cable (All-Dielectric Self-Supported Optical Cable) is a communication optical cable designed for overhead high-voltage power lines. Its key features include being completely metal-free, resistant to electromagnetic interference, and capable of rapid network deployment using existing power towers without the need for additional support lines or power outages.
Characteristics of ADSS Fiber Optical Cable
1.lt Is non-metalc and Insulated, wlth reinforcements mainly made of aramid yarn.
2.lt Is mainly used for overhead Installatlon between electrlc poles and has requlrements for span.Common spans are 50m, 80m, 10om, 120m, and even large spans can reach 400m.
3.ADSS Fiber Optical Cable Include double-sheathed ADSS optlcal cable, slngle-sheathed ADSS optlcal cable, and Minl ADSS optlcal cable. Double-sheathed ones are not commonly used due to high commlsslon and are generally appled In environments with a span of more than 200m that have hlgh requlrements for tensile force; slngle-sheathed ones are usually used In envlronments with a span of no more than 15om and are wldely used In the African market; Mini ADSS Is appllcable for spans within 10om and with no more than 48 cores.

Products Advantages
- All-Dielectric Structure
The all-dielectric self-supporting optical cable adopts an all-dielectric structure with no metal components. This gives our optical cable better electrical insulation performance than traditional metal-armored cables and allows for safe use at distances from high-voltage transmission lines. For example, on high-voltage lines of 35kV and above, the insulation performance of the all-dielectric self-supporting optical cable can reach over 100kV per meter, while ordinary metal-armored cables typically only achieve 10-20kV per meter.
- Self-Supporting Design
The self-supporting design of ADSS fiber optic cables allows them to be directly hung on utility poles or other supporting structures without the need for additional load-bearing steel cables. Compared to ordinary optical cables that require a separate load-bearing cable, ADSS can save 30-50% of installation time. Typically, installing a 100-meter span of ADSS optical cable takes only 2-3 hours, while traditional optical cables may require 4-6 hours.
- High Strength
ADSS fiber optic cables use fiber-reinforced plastic (FRP) with a strength of up to 1200-1500 MPa as the central reinforcement. Its outer layer uses aramid fibers with a tensile strength of 3000~3600 MPa as the load-bearing unit to distribute external tension. Therefore, our optical cable has extremely high tensile strength, typically reaching 3000-5000N, which is about twice that of ordinary overhead optical cables.
FAQ
1. What voltage levels can ADSS Fiber Optical Cable be installed on power lines? How can damage from high voltage be prevented?
ADSS optical cables can be installed on power lines of various voltage levels, from 10kV to 500kV. Preventing electro-corrosion damage is key to its design and application, mainly through the following two methods:
Using a tracking-resistant outer sheath: This is the most crucial protection. Depending on the line voltage and the electric field strength at the installation location, ADSS optical cables are available with either AT type (polyethylene) or PE type (tracking-resistant polyolefin) outer sheaths. PE type sheaths have excellent tracking resistance and arc resistance, and must be used in high-field-strength areas of 110kV and above.
Carefully selecting installation locations: During construction, the electric field distribution is calculated to fix the optical cable in a safe location on the pole with lower electric field strength (such as the lower middle part of the pole), fundamentally reducing the risk of electro-corrosion.
2. Does ADSS Fiber Optical Cable installation require a power outage? What precautions should be taken during installation?
One of the biggest advantages of ADSS optical cables is that they typically do not require power line outages, allowing for live installation, which greatly ensures the continuity of power supply from the grid.
In addition to the aforementioned electric field issues, there are two key mechanical aspects to consider during installation:
Precise sag and tension control: Before construction, rigorous mechanical calculations must be performed based on the span and climatic conditions (wind, ice loads). Specialized tools such as tension laying machines must be used to ensure the optical cable's structural integrity and meets sag requirements during long-term operation.
Complete set of hardware and vibration damping: A complete set of specialized fastening hardware and vibration damping devices (such as spiral vibration dampers) must be used. After installation, it is necessary to check whether the hardware is secure and whether the vibration damping measures are in place to ensure that the optical cable will not suffer fatigue damage under wind vibration.
