ABB supports construction of Asia’s longest city tunnel

Beijing, January 30, 2013 – In the 9.8-kilometer underground circular tunnel of the Beijing Olympic Park, an ABB technical engineer is using his laptop to test a low voltage distribution cabinet.

The circular tunnel, the longest city tunnel in Asia, links all the Olympic venues within the Olympic park and connects to roads around the park via 25 entrances/exits. It is expected that traffic congestion will be greatly improved with the opening of the tunnel later this year.

For this project, ABB has provided motor control devices, Miniature Circuit Breakers, current transformers, and other reliable low-voltage products. The ABB equipment features reliable performance, compact design and simple operation. The motor controllers can remotely control the tunnel’s ventilation system. Real-time monitoring and switching of motors can greatly reduce the costs of maintenance and management. In addition, ABB has also provided a full range of professional low-voltage services, including product commissioning, security diagnosis, installation instruction, and customer training, ensuring the smooth opening of the tunnel.

ABB Low Voltage Products division manufactures products and systems that provide protection, control and measurement for electrical installations, enclosures, switchboards, electronics and electromechanical devices for industrial machines, plants and related service. The division further makes intelligent building control systems, also known as KNX systems, for home and building automation to improve comfort, energy efficiency and security. ABB has 14 low-voltage service stations and more than 40 authorized service suppliers for its low-voltage service across the country, contributing high-quality services to Qinshan Nuclear Power Plant, Guangzhou Metro, and other domestic projects and customers.
