At present, the longest sea-crossing bridge in the world, the Hangzhou Bay Bridge, was opened to traffic on May 1. The cable connector produced by Zhejiang Zuoyi Power Equipment Co., Ltd. will also light the bridge. It is reported that this is the only Chinese private enterprise to provide supporting products for this project.
It is understood that the total investment of the Hangzhou Bay Bridge is about 11.8 billion yuan. It starts from Cixi City in Ningbo in the south and Haiyan County in Jiaxing in the north, with a total length of 36 kilometers. After the completion of the bridge, the distance between Ningbo and Shanghai will be shortened by more than 120 kilometers, forming a two-hour traffic circle with Shanghai as the center of Jiangsu, Zhejiang and Shanghai.
The bridge lighting project is divided into two parts: bridge lighting and landscape lighting. The bridge has installed more than 3,600 various distribution boxes and more than 10,000 sets of other lamps. Most of the products come from international famous brands. It is worth mentioning that more than 20,000 cable connectors for street lamps are from a private enterprise in Yueqing, Wenzhou, which has been engaged in the production of electric power equipment for many years.
According to reports, the entire electrical project bidding of the bridge is hosted by the United States General Electric Company. There are several well-known power equipment companies in the United States, France, Austria and other countries, and there are many large multinational groups. In the competition with the leaders of today's global electrical industry, Zuoyi Company finally won the advantage of leading technology, high quality and suitable for the actual operation needs of the bridge.
As early as 2001, Zhou Zhoulong, the chairman of the company, hired technicians at high salaries and married with famous domestic research institutes. He invested heavily in research and development of insulated puncture clips with 21st century international level. After many technical breakthroughs and continuous innovation, the JJC-type insulated puncture clamp products successfully developed by the company have the world-class level and obtained national patents, filling the gaps in domestic products. Since the new products were put on the market, due to their excellent technical performance, they have been well received by users and their market share has been rising.
