Hainan ADSS-16B1-400-AT optical cable manufacturer direct sales quality assurance price discount including tax and shipping fee

Description :

　　1. The central tubular structural optical fiber is placed in a PBT (or other suitable material) tube filled with water-resistant oil paste with a certain excess length, wrapped with suitable spun nylon yarn according to the required tensile strength, and then extruded with PE (≤ 12KV electric field strength) or AT (≤ 20KV electric field strength) sheath. The central pipe structure is easy to obtain small diameters and has low ice and wind loads; The weight is relatively light, but there is a limit to the remaining length of the optical fiber. 2. The layer twisted structure fiber optic loose tube is wound at a certain pitch on the central reinforcement (usually FRP) and then extruded with an inner sheath (which can be omitted under low tension and small span), and then wrapped with suitable spinning yarn according to the required tensile strength, and then extruded with PE or AT sheath. The cable core can be filled with grease, but when ADSS operates at a large span with a large sag, due to the low resistance of the grease, the cable core is prone to "sliding" and the pitch of the loose casing is prone to change. The use of appropriate methods to fix the loose sleeve onto the central reinforcement and dry cable core can be overcome, but there are certain technical difficulties. The layered twisted structure is easy to obtain safe fiber excess length, although the diameter and weight are relatively larger, it has advantages in medium to large-span applications.
