24 Core OPGW Composite Overhead Ground Wire ACS OPGW Good Quality Stainless SteelFiber Optic Cable
Description:
Stainless steel tube as optical unit in the center of the structure, the outer layer is in a certain pitch-diameter ratio and a certain number of aluminum-clad steel wires or aluminum alloy wires are stranded.
Introduction:
Optical fiber utilizes the difference in refractive index between the core and cladding materials to enable light to be transmitted in the optical fiber, which has become a major revolution in the history of communications. The optical fiber cable is light in weight and small in size, and has been adopted by the power system to transmit information such as dispatch telephones, telecontrol signals, relay protection, and television images between the substation and the central dispatch station. In order to improve the stability and reliability of fiber optic cables, foreign countries have developed a composite structure in which the phase conductors of the optical cable and the transmission line, the overhead ground wire, and the power cable are integrated. The OPGW optical cable is more reliable, stable and firm due to the metal wire wrapping. Because the overhead ground wire and the optical cable are integrated, compared with other optical cables, the construction period is shortened and the construction cost is saved. In addition, if the OPGW twisted by aluminum clad steel wire or aluminum alloy wire is used, it is equivalent to setting up a good conductor overhead ground wire, which can receive the reduction of the potential supply current of the transmission line, the reduction of the power frequency overvoltage, and the improvement of the power line to the communication line. Interference and dangerous effects, etc. Due to its anti-electromagnetic interference, light weight and other characteristics, the optical fiber can be installed on the top of the transmission line tower without having to consider the optimal mounting position and electromagnetic corrosion. Therefore, OPGW has remarkable features such as higher reliability, superior mechanical performance, and lower cost. This technique is particularly suitable and economical when laying or replacing existing ground wires.
