Product Details
Optical Phase Conductor (OPPC) is a specialized new‑type power optical cable. It integrates optical fiber units within phase conductors, delivering dual functions of power energy transmission and optical‑fiber communication. It is primarily applied for power grids of 110 kV and below, including suburban distribution networks and rural power grids.
In medium‑ and low‑voltage power networks, especially distribution lines below 35 kV, ground wires are often not installed, which makes OPGW (Optical Fiber Composite Overhead Ground Wire) impractical for deployment. Phase conductors, by contrast, exist in every power transmission line as indispensable components.
Sharing similar technical principles with OPGW, OPPC embeds optical‑fiber units into conventional phase‑conductor structures. This design fulfills requirements for power‑system monitoring and fiber‑optic networking, offering an effective alternative where OPGW cannot be implemented.

Central Tube
Layer Stranding
Structural Features
- Stainless‑steel tube housing delivers optimal fiber excess length
- Stranded construction combining stainless‑steel tube optical‑fiber units and other metallic wires
- Precisely optimized cross‑section ensures reliable electrical, mechanical‑physical and thermal‑stability performance
Technical Features
- A set quantity of optical fibers are enclosed in laser‑welded, oil‑filled stainless‑steel tube units.
- Fibers placed in loose‑fit stainless‑steel tubes obtain good excess length. For layered‑stranded designs, considerable additional excess length comes from stranding geometry besides the excess length of individual optical units.
- Aluminum‑clad steel (AC) wires provide the primary tensile strength for the cable.
- Hard‑drawn aluminum wires undertake line current conduction and offer partial mechanical strength.
- Adjusting specifications and proportions of AC wires and hard‑drawn aluminum wires for different line conditions yields products matching various mechanical and electrical requirements.
- OPPC is generally applied to ground‑wire‑free medium/low‑voltage transmission systems, including 10kV, 35kV, 66kV and 110kV lines.
