Description
Anti-Tracking ADSS for High-Voltage Power Corridors
Standard PE-jacket ADSS cables can suffer premature jacket damage when installed in strong electric fields on high-voltage towers. In 110kV/220kV environments, contamination (dust, salt fog, industrial pollution) combined with moisture can create conductive paths on the cable surface. This can lead to electrical tracking and dry-band arcing, which progressively burns or carbonizes the sheath.
The ABPTEL AT Jacket ADSS (Anti-Tracking Optical Cable) is purpose-built to mitigate this risk. It uses a specially formulated AT polymer outer sheath designed to resist electrical erosion, significantly improving safety and service life in high-field zones.
What is Electrical Tracking (Dry-Band Arcing)?
Electrical tracking occurs when leakage current flows across a polluted/wet cable surface. As the surface dries unevenly, “dry bands” form, and localized arcing can occur across these dry gaps. Over time, repeated arcing can burn through ordinary PE jackets—leading to sheath failure, water ingress, strength loss, and potential service interruption.
Why Choose ABPTEL AT Jacket ADSS?
- Anti-tracking sheath reduces the risk of surface tracking and arcing damage
- All-dielectric (non-metallic) construction supports safe installation along power lines
- Span / RTS / MAT can be engineered for your tower spacing, route conditions, and mechanical loading
- Suitable for long-term operation in harsh environments (pollution, humidity, UV exposure)
Engineering Note (Important)
Anti-tracking performance depends on space potential, tower geometry, hanging position, climate pollution level, wind/ice load, and installation method. ABPTEL can support selection guidance for AT sheath grade and mechanical design (RTS/MAT/span) based on your route parameters.
