Description
This "All Dielectric Self-Supporting (ADSS)" cable is designed for short, medium and long distance airborne self-supporting applications. ADSS cable provides a fast and economical deployment method for cable TV operators, telephone companies and power companies. It is suitable for power transmission systems across medium and short span conditions and complex terrain such as rivers, mountains, etc. Explanation
The cable consists of 5 to 36 bundles with tubes or fillers, wound up to three layers around the central reinforcement and fixed with a PE outer sheath. Each tube contains 6 to 12 fibers. All core fibers are filled with waterproof glue. The filler can be used to maintain the shape of the cable.
The water-swellable tape is wrapped around the cable core in a spiral. The aramid wires are arranged in a spiral to reinforce the perimeter of the cable. The outer sheath tightly wraps a layer of aramid wires. The cable sheath includes an optional inner polyethylene sheath and an outer polyethylene or AT (anti-skid) sheath. When the induced voltage on the cable surface exceeds 12KV, the AT outer sheath material is used. With AT outer sheath, the maximum electric field strength at the working point can reach 35KV. For long-distance applications, a double-layer sheath design can be considered. Optional pull wires can be placed under the sheath layer for easy removal.
