OPPC optical cable conductor

OPPC (Optical Phase Conductor) is an aerial cable that integrates optical fibers within phase conductors, enabling simultaneous power transmission and communication. OverviewOPPC is designed for use in power distribution networks where traditional ground wires are not feasible, making it an alternative to Optical Ground Wire (OPGW) systems ( ).

Unlike OPG

W, OPPC is energized along high-voltage power lines, meaning it carries current while also housing optical fibers for communication ( ).

Construction

The OPP

C cable combines fiber optic units with phase conductors, typically replacing one or more steel wires in conventional ACSR (Aluminum Conductor Steel Reinforced) cables. Its structure includes: Stainless steel tubes containing optical fibers, often with a capacity of up to 144 cores ( ). Steel core for mechanical strength.

Aluminum alloy outer wires to match the mechanical and electrical characteristics of standard phase conductors ( ). High-temperature resistant anti-corrosion lubricant to protect fibers under operating temperatures of 100–120°C ( ). The optical fibers are installed with excess length to prevent overstretching during operation ( ).

ApplicationsOPPC is primarily used in suburban and rural distribution networks with voltages below 110 kV, especially in 35 kV or lower lines where ground wires are not installed ( ). Key applications include: Power transmission and communication integration. Filling gaps in power distribution automation networks.

Special applications such as transmission line temperature measurement and defrosting ( ).

Technical Characteristics

Voltage rating: Up to 420 kV ( ). Mechanical and electrical properties: Similar to OPGW of the same specification, including resistivity, DC linear resistance, and torsion ( ). Operating temperature: Higher than OPGW due to continuous current conduction ( ).

Insulators and splice boxes: Specially designed to accommodate live line conditions ( ).

Advantages

Combines power transmission and communication in a single conductor. Utilizes existing tower infrastructure efficiently. Suitable for low and medium voltage networks where OPGW installation is impractical.

Provides high mechanical strength and environmental resilience ( ). In summary, OPPC is a versatile solution for modern power networks, offering both electrical and communication capabilities while maintaining the mechanical and electrical characteristics of conventional phase conductors.
