Aluminum Tube / Aluminum Pipe OPGW is an overhead ground wire that integrates optical fibers for communications while maintaining the grounding and shielding function of a conventional earth wire. ●Good anti-corrosion performance and good anti-lightning performance. ●Short circuit. ZTT OPGW is mainly divided into: central-type stainless steel tube OPGW, stranded-type stainless steel tube OPGW, al-covered stainless steel tube OPGW, aluminum tube OPGW, lightning resistant central stainless steel tube OPGW with compressed wires and OPPC. Material and structure are uniform, good resistance to vibration fatigue. Designed to withstand mechanical strain from weather conditions like wind and ice, the OPGW ensures the safe. PBT tube OPGW Construction The core of aluminium clad PBT tube OPGW has structure of stranding pattern,when the multiple optical fiber PBT tubes are into cable, The core of aluminium clad PBT tube OPGW has structure of stranding pattern,when the multiple optical fiber PBT tubes are into cable,a. GYFTA54 is a kind of outdoor communication optical cable, which consists of a non-metallic central strength member, stranded loose tubes, a laminated aluminum tape armor, a PE inner sheath, a stainless. A steel wire is applied as the messenger.
