ADSS fiber optic cable -4-core self-supporting all dielectric&# 40; Below a span of 300 meters; Single layer sheathed power optical cable

Description :

　　[ADS Optical Cable Characteristics]:

　　1. Lightweight, with a small cable diameter and a span of up to 1500 meters;

　　2. Non metallic structure, aramid yarn has uniform stress distribution, good insulation performance, and lightning protection;

　　3. Good anti-corrosion performance, the all dielectric optical cable structure is conducive to installation and maintenance, and can be constructed without power outages. Power failures do not affect the normal transmission of optical cables;

　　4. Wide temperature adaptability range, low coefficient of linear expansion, meeting the requirements of harsh environments.

　　Layered twisted structure: Fiber optic loose tube is wound at a certain pitch on the central reinforcement member, usually FRP, and then extruded with an inner sheath. When subjected to low tension and small span, the sheath can be omitted. Then, suitable spun nylon yarn is wound according to the required tensile strength and extruded with PE or AT sheath. The cable core can be filled with grease, but when the ADSS operates at a large span with a large sag, the cable core is prone to "sliding" due to the low resistance of the grease, and the pitch of the loose sleeve is prone to change. Using appropriate methods to fix the loose tube onto the central reinforcement and dry cable core can overcome the problem, but there are certain technical difficulties. The layered twisted structure is easy to obtain safe fiber optic cables, although the diameter and weight are relatively larger, it has advantages in medium to large span applications.
