On the evening of August 25, 2008, the 29th Summer Olympics came to a magnificent close in Beijing. It was an unparalleled sporting spectacle presented to the world by China and a milestone event showcasing the nation's image to the global stage.

Behind the grand spectacle, numerous Chinese enterprises at the time established dedicated service teams to ensure the successful conclusion of the Olympics. Under the command of the organizing committee, they worked around the clock with great passion and sense of mission to safeguard the event.

As the sole domestic brand supplier of switching devices for the power distribution system of the National Aquatics Center (Water Cube),，TYT Tai Yong Changzheng was also among them. The specialized team they dispatched remained steadfast in their posts for over a month, ensuring the stable operation of the power distribution system and contributing to this century-long celebration.

Therefore, the design and selection of the automatic transfer switch equipment (ATSE), which is the core of power switching, have become one of the key aspects of the "Water Cube" power system construction.

In the early 21st century in China, users were accustomed to using CB-class ATSEs or derivative PC-class ATSEs, but these two types of products had technical limitations such as simple control logic and insufficient reliability. If they were applied in the "Water Cube," there was a possibility of power switching failures, which could lead to unexpected incidents in the safeguarding of key Olympic events.

As a leading enterprise in China's switchgear industry, TYT Tai Yong Changcheng successfully enabled the "Water Cube" to adopt a dedicated PC-level ATSE solution through detailed technical arguments and product test reports conducted in accordance with the international standard "IEC 60947-6-1".

The TYT Taiyong ChangzhengTBBQ3 series dedicated PC-level ATSE is applied to various critical systems such as fire protection, lighting, and fans in the "Water Cube," accounting for over 80% in quantity, achieving a milestone breakthrough for domestic ATSE.

At the 2008 Beijing Olympics, the TYT Taiyong Changzheng TBBQ3 series productswere also applied in over ten Olympic venues such as the National Convention Center, Beijing Workers' Sports Palace, Beijing Fengtai Sports Center, and the Olympic Boxing Training Arena.

At the 2010 Shanghai World Expo and Guangzhou Asian Games, the TYT Taiyong Changzheng TBBQ3 series dedicated PC-level ATSE,was successfully applied to numerous venues such as the China Pavilion at the World Expo, Nansha Gymnasium, Haxinsha Gymnasium, Cycling and Roller Skating Extreme Sports Center, and Yuexiu Gymnasium.

Subsequently, after nearly two decades of R&D and innovation, the TYT Taiyong Changzheng dedicated PC-level ATSE products have continuously expanded, and now possess a comprehensive product system covering voltage levels from 400V to 12kV, including bypass type, neutral line overlap conversion type, and instantaneous parallel type, among others.

Upholding the mission of "enabling electrical technology to transform human life and making energy efficiently serve society," TYT Taiyong Changzheng has always been committed to empowering social development and industry progress through innovative power technology.

In the future, TYT will continue to adhere to the concept of being driven by "technology + market," constantly launching more advanced and reliable power distribution system solutions oriented toward user needs, creating more unique value for users！
