<p>On March 16, with the accurate positioning of the last cable stock, it marked the successful completion of the traction work of the main cable of the Fenglinte Bridge on the Xingyi Huancheng Expressway. Has laid a solid foundation.</p><p><br></p><p>V&T’s high performance and high efficiency<a href="https://www.vectorque.com/products" rel="noopener noreferrer" target="_blank"> frequency inverter </a>has excellent stable performance, and plays an important role in the smooth completion of the main cable traction of the bridge.</p><p><br></p><p>Fenglinte Bridge, the first long-span steel-concrete composite beam suspension bridge in the mountainous area of China, has a height difference of 364.2 meters from the deck to the valley floor, which is equivalent to about 120 floors. The hoisting of the prefabricated middle beam of the 1470-ton main tower weighing 1470 tons has set a world record for the precast hoisting concrete components of mountain valley bridges!</p><p><br></p><p>The main cable construction is the focus and difficulty of the key process of the construction of Fenglinte Bridge, and it is also the main stress system of the suspension bridge. The main cable is divided into two pieces on the left and the right, with a length of about 971 meters and a total weight of 4131 tons. The single-frame main cable has a total of 131 cables (including 4 back cables). Each cable is composed of 91 zinc-aluminum-magnesium coated steel wires with a diameter of 5.45 mm. The maximum weight of a single cable strand is approximately 16.4 tons.</p><p><br></p><p>The winch system configured on both sides of the bridge has very high requirements on the performance, stability and reliability of the drive. The excellent performance of V&T’s V6-H torque vector frequency inverter has played an important role in the main cable traction of Fenglinte Bridge. Both the advanced technology and the stability of the products have been highly recognized and praised by users.</p><p><br></p><p>During equipment commissioning, V&T’s technical engineer Ma Gong needs to walk back and forth on the "catwalk" of the bridge. He said: "The bridge is more than 360 meters away from the bottom of the valley. Just thinking about it has already made" legs soft ". This time it has refreshed the" limit "of his fear of height. Walking on the" cat road ", there is a kind of fog I feel a little nervous but very shocked. I really admire the "iron army" spirit of the bridge builders' hard work, selfless dedication, and hard work.</p><p><br></p><p>Since the start of construction of the bridge, CCTV's "News Network", "Chaowentianxia", "Great Power Transportation", Xinhua News Agency, People's Network and local media have focused on the construction of Fenglinte Bridge and made relevant reports.</p><p><br></p><p>For many years, the high-performance, high-quality inverters and other products developed and produced by V&T have always contributed to domestic infrastructure projects and contributed to the construction of transportation in a big country!</p><p><br></p><p><br></p>
