　　Characteristics of OPPC optical cable:

　　 OPPC (Optical Phase Conductor) is a special type of power optical cable that combines optical fiber units into phase lines, with dual functions of phase lines and communication. OPPC optical cable is mainly used for lines below 66kV that do not require the installation of ground wires, making it impossible to install OPGW. It is especially used in newly constructed 35kV lines and can also be used on 110-220kV lines.

　　OPPC optical cable line is a transmission line composed of two wires and one OPPC, which replaces one phase in a three-phase power system with OPPC. In the design, the mechanical and electrical characteristics of OPPC are mainly considered to match the adjacent two wires. Other aspects are not significantly different from ordinary line design, mainly similar to OPGW optical cable lines, to ensure that OPPC optical cables do not affect the transmission performance and service life of optical fibers during construction and operation. Below is a brief introduction to the design of OPPC optical cable line with one of the phases in the line.

　　 OPPC Overview

　　 OPPC is a method of replacing one or more steel wires in traditional wires with stainless steel tube optical units, which are twisted together with (aluminum clad) steel wires and aluminum (alloy) wires;

　　It is a composite power optical cable with dual functions of overhead power lines and communication optical cables.

　　OPPC can provide channels for special applications such as temperature measurement and ice melting of transmission lines.

　　Development Status of OPPC

　　Optical Phase Conductor (OPPC), also known as OPGW and ADSS, has outstanding advantages in fully utilizing the rich tower and routing resources of the power system. It will effectively fill the gap in the distribution network automation network and realize the automation management network of the entire process from power production to consumption in China.

　　OPPC technology has already been applied abroad (in Europe), with a high operating voltage level of 420kV and good operating conditions. The basic operation in China is on 35kV and 10kV lines. The editor understands that the operation of high voltage 220kV is currently trending towards 500kV and above.

　　OPPC features

　　 energy saving

　　Due to the unequal distance between the lightning rod and each phase conductor, there are some differences in mutual inductance between them. Therefore, although the load current on the three-phase conductor is balanced under normal circumstances, a longitudinal electromotive force still needs to be induced in the lightning rod; If the lightning rod is grounded tower by tower, this electromotive force will generate current, which increases the power loss of the line. This additional power loss is proportional to the square of the load current and the length of the line.

　　save

　　For newly built lines: Line construction and design are completed in one go, improving efficiency and reducing project costs. Iron towers can reduce excess height and strength.

　　Renovation of old lines: There is no need to change the existing conditions of the line, only one phase line needs to be replaced, and the OPPC mechanical and electrical performance is required to be basically the same as the existing phase line.

　　As long as the existing line towers are safe and reliable, there is no need for extensive survey and accounting work when replacing lifestyle habits with OPPC. Avoid reinforcing the tower when using additional fiber optic cables for hanging.

　　There is no possibility of lightning strikes causing broken strands

　　Compared with OPGW, OPPC is safe and reliable, equivalent to normal line phase lines, and there are no incidents of lightning strikes causing broken wires.

　　OPGW serves as both a ground wire and a communication device in high-voltage power lines, but lightning strikes are inevitable and seriously affect communication and scheduling, posing a threat to power grid safety.

　　 Advantages of resisting ice disasters

　　At present, there is no effective ice melting method for OPGW and ground wire in power lines. Using OPPC can greatly improve the line's ability to resist ice disasters.

　　 anti-theft

　　The OPPC junction box, due to its own characteristics, greatly reduces the possibility of theft.

　　It operates with electricity in the circuit;

　　Installed on high-voltage insulators;

　　The installation location is much higher compared to OPGW and ADSS;

　　 OPPC fiber optic composite overhead phase line, core number 2-144, cross-section: 50/8~800/55mm2, in accordance with standard DL/T832-2016
