Structure Design
Description
Double sheaths Aerial ADSS Cable For Long Span are specifically designed for use on overhead HV transmission and distribution lines with steel lattice towers or wooden, concrete or steel poles.
Application
1. Self-support Aerial installation;
2. Fiber-to-the-X networks;
3.Underground duct
Features
1. Stranded loose tube design ensures that the fibers are always free from mechanical strain under the specified loading conditions；
2. Double Jacket designs for medium to long span applications and moderate to heavy ice and wind loading conditions；
3. No metallic or conductive components, allowing the live-line installation (subject to local regulation)
4 Torsion ally-balanced aramid yarn strength elements provide stable cable design；
4. UV-resistant polyethylene sheath is compatible with fittings from all major suppliers and is suitable for use to 12kV space potential；
5. Custom designs for extremely long spans available Track-resistant options are also available for use up to 25kV space potential；
