　　OPPC optical cable

　　Fiber optic composite phase line (OPPC) is a new type of power special optical cable that combines fiber optic units into phase lines. It has dual functions of phase lines and communication, and is mainly used for voltage levels below 110kV in suburban distribution networks and rural power grids. In medium and low voltage power grids, especially distribution lines below 35kV, some can be installed without grounding wires, so it is impossible to install OPGW. In all power grids, only phase lines are essential. In order to meet the requirements of power monitoring or fiber optic networking, OPPC and OPGW technologies are relatively close. By adding fiber optic units in a suitable way to the traditional phase line structure, it becomes a fiber optic composite phase line.

　　feature

　　1. The design of OPPC optical cable is applicable to any newly built medium and low voltage transmission line.

　　2. OPPC fiber optic cable has a similar structure to OPGW, but due to its phase line function, OPPC can carry power transmission for a long time. Therefore, considering the impact of long-term operating temperature on fiber optic transmission performance and fiber optic lifespan.

　　3. The mechanical and electrical properties of OPPC should be consistent with adjacent wires, such as DC resistance or impedance similar to adjacent wires, to ensure that the remote voltage changes maintain three-phase balance.

　　4. OPPC is installed in high-voltage systems, and its installed fittings and accessories (such as tension clamps, suspension clamps, and terminal junction boxes) need to be insulated. The clamps can be made of corresponding insulated tension wire strings or insulated suspension strings. Optoelectronic insulation/separation and connection require special techniques and relatively high construction requirements.

　　advantage

　　1. OPPC's optical fibers are installed inside the phase lines, optimizing the design of transmission lines and achieving significant energy savings

　　2. Serious accidents of broken strands and fibers caused by lightning strikes on the ground wire; Cable operation is safer

　　3. Extremely high economic efficiency

　　4. No accidents such as cable damage or breakage caused by electric corrosion or damage to the optical cable due to the effect of field strength

　　5. High security guarantee system

　　6. There is no hidden danger caused by adding additional line load to the original line

　　7. Natural anti-theft: OPPC and junction box both have high voltage, some have anti-theft advantages

　　application

　　OPPC optical cables are mainly used on power lines with voltage levels below 110KV, such as suburban power grids and rural power grids. Due to factors such as power outages and safety concerns, it is often used on newly built power lines.

　　(1) Replace one phase in a three-phase power system with OPPC to form a transmission line composed of two wires and one OPPC; Mechanical and electrical characteristics are matched with adjacent wires

　　(2) In medium and low voltage power grids, especially for distribution lines below 35KV, some can be used without grounding wires.
