The design of the ADSS cable fully considers the actual situation of the power line and is suitable for different levels of high voltage transmission lines. Polyethylene (PE) jackets may be used for 10KV and 35KV power lines; for 110KV and 220KV power lines, the electric field strength distribution must be calculated to determine the cable hanging point and an electrolytically resistant (AT) outer sheath. At the same time, the amount of aramid and the perfect stranding process are carefully designed to meet the application requirements of different spans.
The ADSS cable adopts a loose-layer twisted structure, and the 250um fiber is placed in a loose sleeve made of a high modulus material, and the loose tube is filled with a waterproof compound. The loose tube (and the filling rope) is assembled around a non-metallic center reinforcing core (FRP) to form a compact core with a water-blocking paste. The outer core of the cable is made of a polyethylene (PE) inner sheath, which is then glued to the reinforcing spun, and finally extruded into a polyethylene (PE) outer sheath or an electrical tracking (AT) outer sheath.
