Description
This "All Dielectric Self-Supporting (ADSS)" cable is designed for short, medium and long distance aerial self-supporting applications. ADSS cable provides a fast and economical deployment method for cable TV operators, telephone companies and electric utilities. It is suitable for medium and short span conditions or complex terrain such as crossing rivers and mountains in power transmission systems. Description
The cable consists of 5 to 36 bundles of wires with tubes or fillers, which are twisted together in up to 3 layers around a central strength member and fixed with a PE outer sheath. Each tube contains 6 to 12 fibers. All core fibers are filled with water-blocking glue. The filler can be used to maintain the geometry of the cable. The water-swellable tape is spirally wrapped around the cable core. Aramid yarns are placed in a spiral manner to provide peripheral reinforcement for the cable. The outer sheath is tightly wrapped around the aramid yarn layer. 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 will be applied. With the 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. An optional pull wire can be placed under the sheath layer to facilitate its removal.
