ADSS optic cable adopts loose tube layer stranded structure, and the loose tube is filled with water blocking compound. Then, two layers of aramid fibers are twisted bidirectionally for reinforcement, and finally a polyethylene outer sheath or an electric tracking resistant outer sheath is extruded.
ADSS cables with this structure are better to be deployed for large span applications. The structure of double jacket ADSS fiber cable has an extra layer of jacket, which improved compressive strength, it also be in a stranded structure design, the inner optical fibers and water-blocking grease are added into the fiber loose tube, and different loose tubes are wound around the central reinforcement (usually FRP). The rest parts are basically similar to the central tube structure. This type is able to obtain longer fiber lengths.
The Fiber Cores of ADSS Fiber Cable is 2-288Cores
ADSS fiber optic cable is All-dielectric self-supporting wire, without any metal for avoid lightning strike. It is very convenient line installation and maintenance. The ADSS fiber cable withstand voltage, has good anti-electric corrosion performance, anti-lightning strike, can be laid on transmission line towers with voltage level of 500kV, and has strong anti-bullet strike performance. The inner structure use a water-blocking layer for better waterproofing. Aramid Yarn is a important part for fiber optical cable for tensile resistance.
The special design of ADSS fiber cable suitable for installation on Power Transmission Lines and nearby Power Utilities. This ADSS fiber optic cable type is aimed to be used for voice, data, broadband and CATV transmission in Long Distance, Backbone and Local Area Networks with Aerial installation method.

Fibre & Loose Tube Colors
All-dielectric self-supporting (ADSS) cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements.
UnitekFiber can supply ADSS fiber optic cable with 100-800 meter pole span.
Dielectric means it has non-conducting properties of a non-metallic, insulating material that resists the passage of electric current.
ADSS cables should be placed in Aerial and duct, but can not be direct-buried.
I am extremely impressed with your products, fiber optic cable. My father would have loved buying these products from your company.
