OPPC (Optical Phase Conductor) is a special power optical cable that embeds an optical fiber unit inside a traditional overhead phase conductor. Its core feature is that it serves as both a live phase conductor and a communication medium, filling the application gap where OPGW cannot be used because there is no ground wire on the pole tower.

✔ Fills the gap for lines without ground wires: For 35kV and below distribution lines, or older lines without ground wire supports, OPGW cannot be deployed, while ADSS has risks of breakage due to wind deflection or external damage. OPPC can directly replace one of the phase conductors, naturally possessing the same lightning protection, anti-theft, and anti snagging reliability as the phase conductor itself.
✔ No additional tower load: It is a phase conductor itself, requiring no additional load, and is particularly suitable for the renovation of old lines with limited tower strength.
✔ No need for tower reinforcement: In old line renovation, deploying OPGW or ADSS often requires tower reinforcement, while OPPC generally does not, resulting in a shorter construction period.

Application

✔ Medium and low voltage distribution lines (35kV and below): This is the primary application scenario for OPPC, solving the problem of reliable communication channels for lines without ground wires.
✔ Old line communication renovation: When OPGW cannot be deployed due to tower structure, safety distances, or strength limitations, OPPC is a viable alternative.
✔ Special environments: For example, coastal salt spray corrosion areas, heavy ice areas, or large span sections, where specialized OPPC with corrosion resistance and ice resistance can be designed.
