Aluminium Clad PBT Tube OPGW Cable

Seamless aluminum tube has uniform texture, consistent with the texture of the whole ground aluminum clad steel wire, no electrochemical corrosion 

Good fatigue resistance profit by consistence of texture and structure of the whole ground wire 

Optical fiber of aluminum tube OPGW are exist in PBT tube, the core which is clad with a layer of thermal insulation material, with good thermal insulation effect and good protection effect of fiber optics, and short-circuit current has little influence to transmitting performance of fiber optics
