众所周知,高效电力输配系统需要有一个通信网络。这样一个通信网络便于有效地保护信号传输、控制数据的传输、远距离测量、通话等。大约12年前,BICC电缆公司就预见到,对通信系统无论在容量还是可靠性方面,要求将越来越高。同时它还认定,光纤这项新技术在此领域的优势,所以着手研制一种光纤并入架空地线的系统。此项研究的成果就是FIBRAL——在全世界获得专利的架空地线复合光缆。 1979年,英国进行了FIBRAL的首批试验,法国、美国和加拿大于1980年和1981年紧随其后。在试验无故障运行了两年之后,FIBRAL地线作为一个运转系统,于1981年安装在CEGB Fawley-Nursling 400kV 23km长的线路上。因此,架空地线复合光缆运行已超过10年,且可成为一种成熟的
As we all know, efficient power transmission and distribution systems need to have a communication network. Such a communication network to facilitate the effective protection of signal transmission, control data transmission, long-distance measurements, calls and so on. About 12 years ago, BICC Cable Company foresaw that the requirements for communication systems will be higher and higher, both in terms of capacity and reliability. At the same time, it also determined that the new technology of optical fiber has the advantage in this field, so I started to develop a system of optical fiber into the overhead ground wire. The result of this research is FIBRAL, a patented overhead ground-based composite fiber optic cable. In 1979, Britain conducted the first trials of FIBRAL, followed by France, the United States and Canada in 1980 and 1981. After two years of trouble-free operation of the test, the FIBRAL ground was installed as a running system and was installed on a CEGB Fawley-Nursling 400kV 23km long line in 1981. As a result, overhead ground-based composite fiber optic cables have been in operation for over 10 years and can become a mature one
