Project Name: Wuhan Metro Line 21 Substation Intelligent Distribution Automation System
Model: MIEN2208 and MSICOM7220G-4GF-16GT
City: Wuhan, China
Wuhan Metro Yangluo Line (namely Line 21) was scheduled to open at the end of 2017. The Yangluo Line will pass through the three districts of Wuhan Jiangan, Huangpi and Xinzhou, with a total length of 35 kilometers and 16 stations (6 underground stations, 10 elevated stations). Line 21 is currently designed to have a speed limit of 100 kilometers per hour, which is 20 kilometers faster than the current maximum speed limit of 80 kilometers for subways in the main urban area of Wuhan. Line 21 is known as the fastest subway in Wuhan.
The intelligent power distribution automation system for substations along Wuhan Metro Line 21 uses the MSICOM7220G-4GF-16GT managed industrial switch and MIEN2208 unmanaged industrial switch to create a power communication network. Provide reliable network support for the stable power supply of Metro Line 21.
