A Study on the development of optical fiber incorporated high-voltage underground power cable

In this study, We developed the optical fiber incorporated high-voltage underground power cable which is combined optical fibers with conventional high-voltage underground power cable. Optical-Unit that optical fiber is inserted in stainless tube is tested, and we got good results enough to safe optical fibers. Also we put the optical fiber incorporated high-voltage underground power cable to the test of electrical characteristics and optical characteristics, we knew that the electrical characteristics were the same characteristics as conventional high-voltage underground power cable and the transmission loss change was almost zero.
