Description
Product Overview
The Double Jacket ADSS Cable (200M–1500M Span) is a high-performance all-dielectric self-supporting fiber optic cable designed for the most demanding long-span aerial crossings — rivers, valleys, highways, and high-voltage transmission corridors. The dual-layer HDPE sheath with water-swellable tape between layers ensures reliable operation in extreme environments where single jacket designs fall short.
Every cable is custom-engineered to your specific span and loading requirements. ZTO provides span-by-span sag-tension calculations, MAT verification, and hardware compatibility charts — not just a product, but a complete engineering solution. CORNING fiber, 100% OTDR tested, with full IEC 60794 test reports.

Applications
- Extra-High-Voltage Transmission Lines (≥110kV): OPGW replacement or co-location on existing transmission towers with full dielectric safety.
- Long-Span Crossings: River, valley, and highway crossings up to 1500M — eliminating the need for intermediate support structures.
- Inter-City Backbone Networks: High-capacity fiber backbones leveraging existing power infrastructure corridors.
- Heavy Ice & Typhoon Zones: Custom icing load and wind load design for extreme weather deployments. Contact ZTO engineering for site-specific calculations.
