OPPC composite phase cable is a new type of special power cable. It embeds optical units inside phase conductors to realize dual functions of power transmission and optical communication. It is mainly applied for 110 kV and below power systems, such as suburban and rural distribution networks. In medium and low-voltage networks, especially 35 kV and below, ground wires may not be available, making OPGW installation impossible. Phase conductors are indispensable in all power grids. To satisfy the demands of power monitoring and fiber-optic networking, optical units are integrated into conventional phase conductors, forming this new composite optical fiber phase cable.

This cable adopts a loose-tube stranded structure. Optical fibers are placed inside loose tubes made of high-modulus polyester. Loose tubes and fillers are stranded around FRP to form a compact cable core filled with water-blocking gel. A PE inner sheath is extruded over the cable core, then two layers of aramid yarn are wrapped, and a PE or AT outer sheath is extruded in the final step.
OPGW combines ground wire and optical communication functions. It is mainly used as communication cables for newly-built overhead high-voltage power systems of 35 kV, 110 kV, 220 kV, 500 kV, 750 kV and above. It can also replace existing ground wires in legacy overhead high-voltage power networks to add optical communication channels, carry short-circuit current and provide lightning protection. The cable structure is scientifically designed according to the user’s operating environment, and custom structural designs are available upon request.
“In the '97 Fiber Optic Year', China's Four Seas Fiber Optics actively promoted fiber optic communication technology in China with the help of the global leading technology of the US Fiber Optic Network Research Institute. During this 26 year journey, outstanding contributions have been made to the country's broadband IP network and fiber to the home field. The entire series of CNFIBERNET brand fiber optic communication products are also exported to 66 countries and regions worldwide.
