APAR designs and manufactures OPGW cables using advanced stranding technology, precision fiber integration processes, and stringent quality control systems. Optical fiber composite overhead ground wire (OPGW) 1. Application OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system. 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. Stainless steel tube OPGW: stainless. One company that stands out in this competitive industry is Hunan Jiahome a leading player in the production of Optical Ground Wire (OPGW) cables. This essay aims to introduce and delve into the key aspects of Hunan Jiahome, shedding light on its contributions to the field of OPGW cable. Fibre Optic Overhead Group Wire Optical Ground Wire (OPGW) is used in power utility for dual function as a ground or static wire and a path for transmission of voice, video or data signals through optical fibres allowing for fast, reliable and cost effective installations. Installed at the top of high-voltage and extra-high-voltage transmission lines, OPGW cables provide lightning.
