ABB power distribution technology adds new momentum to Chongqing Rail Transit

Recently, abb announced to provide low-voltage distribution solutions for phase II of line 6 branch line of Chongqing Rail Transit (Group) Co., Ltd. Since 2012, abb has successively provided stable services for Chongqing rail transit lines 2, 4, 5, 6 and 10 and ring line projects, improved the reliability and safety of power distribution system operation, helped build a convenient urban rail transit network, and provided strong support for Chongqing's urban infrastructure construction. In the phase II project of Chongqing Rail Transit Line 6 branch line, ABB's latest Emax 2 air circuit breaker, OT disconnector, S200 miniature circuit breaker and new Tmax XT molded case circuit breaker have been successfully applied, providing a more reliable and simple operation mode for customers' operation and maintenance. Among them, abb Emax 2 air circuit breaker integrates multiple functions such as system protection, load protection, generator management, electric energy measurement and analysis, which can solve the electrical problems that may be encountered in the rail transit distribution system and control and manage efficiently; At the same time, it also supports the subsequent installation of digital modules to support future upgrading and expansion. The phase II project of Chongqing Rail Transit Line 6 branch line has a total length of 14.022km, including 8.994km underground line, 4.901km elevated line and 0.127km subgrade line. There are 7 stations, including 5 underground stations, 2 elevated stations and 2 transfer stations. The project is expected to be completed by the end of 2020. Zhao Yongzhan, head of ABB China Electric Division, said: "More convenient, environment-friendly and three-dimensional urban rail transportation is an effective measure to solve the traffic problems in big cities. ABB has a comprehensive product line and professional service capacity to provide complete electrification solutions for rail transit, and provides users with safer, intelligent and efficient power distribution solutions based on advanced sensing technology, industry data and artificial intelligence Help users improve the power distribution level, reduce operation and maintenance costs, and create greater value for customers with technological innovation. " ABB has always supported the sustainable development of Chongqing through leading electrical and automation products and solutions, and participated in the construction of many key projects such as Chongqing Jiangbei Airport, Chongqing Nanchuan gymnasium, urban light rail and Chang'an Ford Chongqing plant.
