All-Dielectric Construction
ADSS fiber optic cables are made entirely of non-conductive materials, making them safe for installation near energized power lines and eliminating the need for grounding.
Self-Supporting
Designed to support their own weight and environmental forces like wind and ice, negating the need for a separate messenger wire.
High Tensile Strength
Utilizes materials like aramid fiber yarns to achieve high tensile strength, allowing the cable to withstand various environmental stresses.
Environmental Resistance
Engineered to resist UV radiation, temperature fluctuations, and moisture, making them suitable for diverse climates.
Long Span Capabilities
ADSS cables can span considerable distances between support structures (poles or towers), reducing the number of supports needed.
The actual status of overhead power lines is taken into full consideration when ADSS cable is being designed.
For overhead power lines under 110kV, PE outer sheath is applied.
For power lines equal to or over 110kV, AT (Anti-tracking) outer sheath is applied.
The dedicated design of aramid quantity and stranding process can satisfy demand for 100m and 200m spans.
Frequently Asked Questions
1. What makes ADSS cable suitable for high-voltage environments?
ADSS cable features an all-dielectric construction, meaning it contains no metal components. This eliminates electrical interference and the need for grounding, allowing it to be installed safely on high-voltage power lines.
2. When should AT (Anti-tracking) sheath be used instead of PE?
A PE (Polyethylene) outer sheath is used for power lines under 110kV. For power lines reaching or exceeding 110kV, an AT (Anti-tracking) sheath is required to withstand higher inductive voltages, which can reach up to 25kV.
3. Does ADSS cable require a separate messenger wire for support?
No, ADSS (All-Dielectric Self-Supporting) cable is specifically designed to support its own weight and environmental loads from wind and ice without the need for a separate support or messenger wire.
4. What is the maximum span distance for these cables?
ADSS cables are highly versatile with typical spans ranging from 80m to 500m. Depending on the design and aramid yarn reinforcement, the largest spans can exceed 1000m.
5. How does the cable protect against moisture?
The cable utilizes a loose tube stranded design where the tubes are filled with a water-resistant filling compound, providing excellent protection against moisture ingress.
6. Can ADSS cable be installed while the power lines are active?
Yes, one of the primary advantages of ADSS cable is that it can be installed without shutting off the power, minimizing service disruptions for the utility provider.
