The reporter learned from the Qingdao-based Qingdao Sifang Locomotive and Rolling Stock Co., Ltd. in Qingdao on the 9th that the first train of the Delingha Hyundai tram project will be rolled out of the company on that day, and it will be the first modern tram to enter the Qinghai-Tibet Plateau. Operate the highest tram on the train.
The company's chief designer, Li Yankun, said that unlike conventional trams, Delingha's modern tram is a new type of hybrid energy storage modern tram with a supercapacitor and lithium titanate hybrid energy storage system. When the tram operates normally, it is powered by a super capacitor. When the super capacitor is not able to replenish the battery in time, the lithium titanate battery supplies power to the vehicle.
Li Yankun said that this hybrid energy storage technology has the advantages of fast charging speed, reliable operation, and green environmental protection. With the advantage of supercapacitor 'fast charge and fast release', vehicles can quickly complete charging within 30 seconds of a stop time. The tram only needs to set up the charging piles at the stations along the way. There is no need to set up a traditional power supply contact net across the line, which not only saves costs, but also does not have the 'dumplings' on the roof to better protect the urban landscape. Lithium titanate batteries are equivalent to super Capacitance adds an 'insurance' to make trams have more life-saving emergency response and more reliable operation.
The Delingha Modern Tram will become the first modern tram to enter the Qinghai-Tibet Plateau, and it is also the world’s highest-operated tram.
It is reported that Delingha's modern trams are organized into two modules, each with a maximum of 168 passengers and a maximum operating speed of 70 kilometers per hour. To meet the demand of the highland environment in Delingha, trams have been targeted for design. The insulation performance of the train electrical equipment is demanding. The electrical system of the train adopts a high standard design, which increases the electrical clearance of the electrical equipment to prevent breakdowns and ensure safe and reliable operation of the tram. At the same time, the vehicle also uses cold-resistant materials. Adapt to the low temperature environment of Delingha.
Located in the central part of Qinghai Province, the city of Delingha is located at the altitude of nearly 3,000 meters. It is the seat of the prefecture of the Mongolian Tibetan Autonomous Prefecture of Haixi. It is an important postal station of the Southern Silk Road and is also an important node of the New Silk Road Economic Belt. The project is the first tram line on the Qinghai-Tibet Plateau, and it is currently the world’s highest tram line. The line has a total length of approximately 14.36 kilometers and consists of 19 stations. It is expected to open in 2018.
