OPGW CABLES

Optical Ground Wire (OPGW) features a central aluminium-clad stainless steel tube with aluminium-clad steel (ACS) and aluminium-alloy (AA) wire layers. It serves as both a grounding conductor and a fiber-optic communication medium, ensuring fast, reliable, and cost-effective data, voice, and video transmission while protecting power infrastructure. The optical fibres are enclosed in a central aluminium-clad stainless steel tube, surrounded by a layer of ACS wire and a layer of AA wire. This construction enhances mechanical strength, conductivity, and corrosion resistance. The cable offers high tensile strength, excellent crush resistance, and long-span capability, while its lightweight design reduces the load on transmission towers. Ideal for high-voltage transmission networks, this OPGW solution provides durability, stability, and superior performance in challenging environments.
