　　The RRT Group's 12 core ADSS optical cable mainly includes two types of sheaths, ADSS-PE/ADSS-AT. The span (span) of the two types of optical cables ranges from 100 m to 1500 m, and the cable structure adopts a loose sleeve layer twisting structure. The 12 core ADSS optical cable consists of 2 loose sleeves (12 250 μ m optical fibers are wrapped in two loose sleeves made of high modulus polyester material [6+6]), and 3 filling ropes wound around the center non-metallic reinforcement member (FRP) to twist into a round cable core. The gaps inside the cable core are filled with water-resistant oil paste, and the outer polyethylene (PE) sheath of the cable core is used. Then, two layers of aramid yarn are twisted in both directions for strengthening, and extruded polyethylene (PE) is used. Outer sheath or electrically corrosion-resistant (AT) outer sheath.

　　ADSS optical cables are installed on high-voltage transmission lines, with a general lifespan of over 25 years. There are many factors that affect their lifespan, including:

　　(1) The gradient of the high-voltage induced electric field near the tower varies greatly, and the high-voltage induced electric field has strong electrical corrosion on the optical cable. Generally, PE type is used for overhead power lines of 35KV and below, and AT type is used for lines of 110KV and above;

　　(2) For double circuit towers, due to power outages or line modifications in the first circuit, consideration should be given when selecting hanging points; (3) When the line passes through a working area with salt spray and acid gas, chemical substances will corrode the outer sheath of the optical cable, damage its electrical protection sleeve, and be easily damaged by electric arcs

　　The construction of ADSS optical cables is usually carried out on live line towers, and insulated endless ropes, insulated safety belts, insulated tools must be used during construction. The wind force should not exceed level 5, and a safe distance must be maintained from lines of different voltage levels, namely 35KV greater than 1.0m, 110KV greater than 1.5m, and 220KV greater than 3.0m
