Description
Heavy Duty Double Jacket ADSS for Long-Span Aerial Deployment
The ABPTEL Long Span Double Jacket ADSS (All-Dielectric Self-Supporting) cable is engineered for aerial installations where span length, tensile safety margin, and physical protection are critical. Unlike standard single jacket designs intended for short distribution runs, this heavy-duty structure is built for 200m–600m spans across open terrain—such as rivers, valleys, highways, and mountainous corridors.
Built for Mechanical Strength and Field Reliability
This cable uses a stranded loose tube design with tubes filled with a water-resistant compound and stranded around a non-metallic FRP central strength member. A reinforced layer of aramid yarn serves as the dielectric strength member, enabling a high RTS and controlled MAT during installation.
The double jacket (inner sheath + outer HDPE sheath) acts as a dual-layer protection system:
- The inner sheath protects the core even if the outer sheath is scratched or locally damaged.
- The outer sheath provides the first defense against abrasion, UV exposure, and environmental wear.
Where It’s Used
Long span double jacket ADSS is typically chosen for:
- River / valley crossings and wide gaps between structures
- Backbone aerial routes along power corridors and telecom pole lines
- Environments with higher risk of mechanical stress, wind load, or wildlife interference
- Projects that require clear engineering parameters such as RTS / MAT / Span
Engineering Note (Span Design)
Actual span capability depends on pole/tower geometry, sag-tension design, wind/ice loading, and installation method. ABPTEL can provide span calculation support and recommend RTS/MAT based on your route conditions.
