August 9, 2010, by the North China Power Grid Technology Co., Ltd. and Shenzhen SDG Information Co., Ltd. jointly developed the "220kV OPPC fiber-optic communications wire temperature plus intelligent video surveillance" in North White Deer 220kV power line hanging success Operation. OPPC optical fiber communication video temperature measurement lead successfully applied to 220kV transmission line, is the first time in the world. The total length of this optical fiber communication temperature measurement and video monitoring smart wire line is 26.193 kilometers, the tower is 69 bases, OPPC design core number is 24 cores, including 8- core temperature measurement fiber and 4- core video monitoring fiber. Allegedly, this wire is currently in the front end of the international arena whether it is in the voltage level, the total length of the line, the functional settings or the fiber optic splice closures. The successful implementation of this scientific research achievement and solution will not only help analyze and control the operation of the line. Transport load, improve the maximum economic efficiency of power transmission lines, reliability and safety of power supply, and also provide practical experience and theoretical guarantee for the promotion and practical application of OPPC . In order to realize the unattended substation , remote monitoring of transmission lines and multi-networks The integration construction provides new technical means, and provides a new multimedia communication carrier for the construction of national smart grid .
