Introduction
OPPC (Optical Phase Conductors) are the combination of a phase conductor commonly used for energy transport with an optical core for data transmission.
OPPC (Optical Phase Conductor) is typically used in overhead power lines without ground wires, where OPGW (Optical Ground Wire) cannot be installed.
Optical Fiber Composition Phase Conductor (OPPC) is the optical cable that compounds the fiber in the phase conductor.
OPPC makes full use of the power system's own line resources to avoid conflicts with the outside environment in frequency resources, routing coordination, electromagnet compatibility and so on, it is a new type of special power optical cable for power communication. In the 1980s, some countries allowed OPPC to be used in power system below 200KV, and they were already set up to operate in Europe and America.
In the current power grid of our country, the three-phase power system transmission is generally adopted, and the power communication of the system is normally operated in the traditional way. If replace one phase of the three- phase with OPPC to form a three-phase power system which is composed of two conductors and one OPPC, then no communication lines would be extra needed to solve the problem of automation, control and communication, etc., and it can greatly improve the quality and quantity of the transmission.
Advantages
Their dual use (power and data transmission), combined with specific accessories, allows to make even more modern and efficient overhead power lines, creating an extensive infrastructure network for data transmission even without the OPGW (Optical Ground Wire). With application in power transmission lines, due to its excellent performance in low and medium voltage electrical networks.
OPPC is a new type of special electrical cable that makes up the unit of fiber in the phase with the function of phase and communication. It is mainly applied in low voltage classes 110kV, urban power distribution network and rural power network. For the low and medium voltage power network, especially in the power distribution line that is less than 35 kV, some of them can not be installed with OPGW because it is possible to use ground cable. In all electrical networks, only the phase is essential. To meet the requirements of electrical monitoring or fiber optic networks. In the traditional structure of the phase, add in the fiber unit with the appropriate method, which can become fiber optic phase conductor.
Engineering design and construction
OPPC in engineering construction can refer to the design specifications of OPGW and three-phase conductors, such as sag tension, calculation of the hanging point, distributed disks and span, etc.,
In the construction of OPPC, it is necessary to separate the fiber unit from the operating phase conductors, which involves the technology of fiber connection and photoelectric separation, the connection technique and high voltage insulation are highly required.
OPPC connection box is different from that of other optical cables, it is divided into transition connection box and terminal connection box. On the basis of the mature products abroad, similar products have already been developed by ourselves.
At present, our company has successfully run several lines under 10KV, 35KV, 110KV, 220KV and so on, and the first OPPC route was put into operation in the Tiger Pit power plant.
Main Features:
Resistant to traction.
Mechanical-electrical characteristics coincide with those of the adjacent second phase conductors.
Placement OPGW or ADSS.
Provides the optical path of the cable.
