Zhongda communication power supply escorts China's first high-altitude "golden channel"

the second double track project of Lanzhou Xinjiang Railway is China's first high-speed railway built in high-altitude areas. At present, the Xinjiang section of the project has entered the electrification construction. After the completion of the railway, it will become an important golden channel for passenger and freight transportation from east to West in Xinjiang. A series of communication power supply products such as mcs3000e provided by Zhongda Diantong, a leading domestic communication power supply professional manufacturer, will provide strong impetus for the smooth operation of Xinjiang section of Lanzhou Xinjiang second line

Zhongda Diantong has been committed to providing professional power integration solutions for industrial users. The mcs3000e series products it provides for this project are a combined series of high-frequency switching power supply systems developed by the company based on many years of design and manufacturing experience and in accordance with the actual situation of domestic electricity and the requirements of energy conservation and emission reduction. This series of power supplies can withstand a wider range of AC input voltage and a wider range of operating temperature, and can better adapt to different applications. The rectifier module adopts advanced soft switching conversion technology, which has high efficiency in a wide range of load rates, and the AC input harmonic current is small, so that the system has higher reliability

the second double track project of Lanzhou Xinjiang Railway has about 250 points, including 2 hub communication machine rooms, 16 station communication machine rooms, and about 232 section signal relay stations and section base stations. According to its engineering characteristics and layout, the power supply scheme of mcs3000e communication power supply can be roughly divided into two categories, namely, the power supply scheme of station/hub communication machine room and the power supply scheme of interval communication station. The load of the station/hub communication machine room is large, and the system capacity configuration is generally between 300A and 600A. The backup battery adopts 600ah~1000ah external battery pack. The load of the section communication station is small, and the system capacity is between 90a and 200A. The backup battery adopts 50ah~150ah built-in battery pack

Zhongda Diantong will successively complete the supply of equipment required by the project in the second half of the year, and assist in the installation, acceptance, opening, trial operation and other work. The second double track project of Lanzhou Xinjiang Railway, with a total length of 1776 kilometers, traverses Gansu, Qinghai and Xinjiang. It is the world's longest high-speed railway built at one time, with a design speed of more than 200 km/h and a construction period of 5 years. It is planned that the whole line will be officially opened to traffic in 2014. As the first high-speed railway project built by the country at high altitude, plagued by many problems such as excessive industrial capacity and rapid growth of new capacity, the second double track of Lanzhou Xinjiang Railway plays a decisive role in the national railway construction project

when it participated in such projects for the first time, it defeated many strong competitors and won the bid successfully. The mcs3000e communication power supply scheme provided by it has greatly shortened the construction cycle of the project, reduced its procurement costs, reduced user operating costs, enhanced the core competitiveness of customers, and laid a good foundation for further development of high-altitude high-speed railway projects in the railway industry in the future
