What is the relevance of rail connectors to rail construction?

In recent years, the support for rail transportation construction is increasing. The reporter learned from the relevant rail transit business undertakings of the company was informed that the Meishan Railway was officially opened to traffic on October 11, and the opening of this railroad is inseparable from the help of rail transit connectors. Has been, rail transportation construction in China's industrial society has been highly supported. The reporter learned from the relevant construction unit, China's newly built Meishan Railway was officially opened to traffic on October 11th. Across the country, there are also many projects using rail transit connectors. In Chongqing Municipality, for example, nine new lines were built in the fourth phase of the rail transit construction plan released. Meanwhile, Hangzhou has released a list of rail transit lines for 2025. It is expected that Line 3 will continue to be extended and Line 9 will be moved significantly. Coincidentally, Suzhou is also speeding up the laying of its rail transit network, when six lines will be built together.

As one of the components supporting rail operation, the role of rail transportation connectors is particularly important. According to the "13th Five-Year Plan for Railway Development", by 2020, the operating mileage of the national railroad will be close to 150,000 kilometers, of which 30,000 kilometers will be high-speed railroads. In this context, according to the Vision Industry Research Institute estimates, the 2018-2020 rail transit connector market demand is about 3.058 billion yuan; from 2020 to 2023, China's rail transit connector market demand is about 2.136 billion yuan. New products are launched one after another From the forecast data, the layout still needs to be advanced. Many rail transit connector manufacturers have also realized this, have entered the market. Previously, after experiencing rapid growth in the industry as a whole, China's rail transportation connector industry is entering a "new normal". Railroad locomotives, railroad coaches, rolling stock and urban rail vehicles market capacity directly determines the market capacity of the rail transportation connector industry. In the interview, industry insiders said that the current rail transportation connector market development is relatively stable. 2018 high-speed rail marginal opening mileage upward, indicating that the future demand for rolling stock will remain strong, is expected to maintain the annual demand of 350-400 rolling stock by 2020. Statistics show that, from the view of urban rail transit vehicles, the urban rail transit mileage opened in 2017-2020 was 812, 687, 597 and 1836 kilometers, respectively, and the urban rail transit mileage continued to maintain a high level. It can be seen that more and more rail transportation connector enterprises began to vigorously layout. Industry insiders told reporters, "In addition to meet the high speed, strong vibration and high temperature working environment, we also need to withstand heat, vibration and salt and other harsh factors, because the connector is externally installed." With the high-speed signal transmission, digitalization, integration of various signal transmission, miniaturization of product size, miniaturization, modular combination and plug-in convenience, how to ensure the reliability of each connector connection has become a very difficult subject.
