ADSS Single-mode Aerial Optical Cable
A utility already owns a high-voltage line, a row of towers, and a corridor that crosses the countryside. What it often lacks is a way to carry communication between its substations without digging, without leasing, and without shutting the line down. The ADSS Single-mode Aerial Optical Cable answers with a lightweight, all-dielectric cable that hangs directly on the existing towers, safely below the live conductors.
Life Along the Electric Field
Hanging a cable near energized conductors is not the same as hanging it anywhere else. The air around a high-voltage line holds a strong electric field, and a cable surface exposed to that field can suffer dry-band arcing - tiny discharges that, over years, erode an ordinary jacket. ADSS solves this with an anti-tracking jacket designed to resist leakage current and carbonized paths. The higher the line voltage, the more carefully the jacket grade is chosen: standard polyethylene for low fields, anti-tracking grades for intense ones.
Strength in a Lightweight Form
An ADSS cable carries no steel, because steel inside an electric field behaves like an antenna. Instead, the strength layer is aramid yarn, the same family used in body armor, laid around the core. Aramid delivers tensile strength at a fraction of steel's weight, and it is dielectric, so the cable stays electrically inert from end to end. The payoff is a span that can stretch hundreds of meters while held by nothing more than a pair of tower clamps.
Engineered to Hang Free
Self-supporting means the cable must carry its own weight, plus wind and ice, across every span. The design begins with a sag study for the longest distance, adding regional ice and wind loads to settle the aramid content and the hanging point on the tower. ADSS is tuned per route, not pulled from a catalog: the same core can be built with different strength ratings for a short urban span or a wide river crossing.
Installed Without Powering Down
The retrofit advantage is the reason most utilities choose ADSS. Because nothing on the tower is replaced and nothing conductive is added, the line stays energized during the whole job. A pulling rope rides along the tower line, the cable is guided into its clamps, and the crew works under standard overhead clearance rules. Substations are connected by the end of the week - no scheduled blackout.
Applications in Utility Networks
Substation-to-substation links: SCADA and protection traffic ride the utility's own rights-of-way
Rural feeder monitoring: distribution lines gain telemetry for reclosers and remote switches
River and valley crossings: long lightweight spans clear obstacles that make trenching expensive
Railway and pipeline corridors: shared infrastructure carries control data along the same route as the asset itself
Why Utilities Pick ADSS
Zero outage, zero tower modification: communication is added without touching the live network
No induction worries: the all-dielectric body cannot couple the line's magnetic field, so no grounding accessories are needed
Lightweight and long-span: fewer supports and simpler hardware than metal-armored alternatives
Room to grow: single-mode fibers ordered in surplus become future services or leased capacity

ADSS cable is loose tube stranded. Fibers, 250μm, are positioned into a loose tube made of high modulus plastics. The tubes are filled with a water-resistant filling compound. The tubes (and fillers) are stranded around a FRP (Fiber Reinforced Plastic) as a non-metallic central strength member into a compact and circular cable core.
After the cable core is filled with filling compound. it is covered with thin PE (polyethylene) inner sheath. After stranded layer of aramid yarns are applied over the inner sheath as strength member, the cable is completed with PE or AT (anti-tracking) outer sheath.
Characteristics
1. Large span lengths and the largest span is over 1700 m.
2. Non-metallic material, with high insulating property performances as well as lightning-proof.
3. Special anti-track outer sheath protection, strong anti-electro-corrosion ability.
4. The aramid yarn ensure the cable's tensile resistance, and also have good bullet-proof performance.
5. Light weight with small diameter, reducing the load caused by ice and wind as well as the load on the tower.
6. Can be installed without shutting off the power.

FAQ
Q1: Will the cable erode while hanging near high-voltage lines?
Ordinary jackets can develop tracking under dry-band arcing. ADSS jackets are graded for the route's electric field - anti-tracking material where fields are high - and verified by tracking-resistance testing before supply.
Q2: Can installation really happen with the line energized?
Yes, that is the point of the design. The cable is all-dielectric, adds no conductive path, and is placed with approved clearances from the phase conductors under standard live-line safety procedures.
Q3: What is the maximum span length?
Typical ADSS designs cover spans from 100 meters up to about 1000 meters, depending on aramid content and the regional wind and ice loads. The sag study supplied with the order confirms the actual limit for each route.
Q4: How do I choose between standard and anti-tracking jackets?
The deciding factor is the electric field at the hanging point, which depends on line voltage and cable position. The supplier calculates the field for your tower profile and recommends the grade - when in doubt, anti-tracking is the safer investment.
Q5: Does lightning pose a threat to ADSS?
Because the cable is fully dielectric, it does not conduct lightning surges or attract strikes the way metal members do. It is also immune to the electromagnetic noise of the line itself, which is exactly what makes it reliable inside a high-voltage corridor.
