When the renaissance train “spreads”, the local iron travels underground in the city, few notice the invisible “wing” on the roof of the car — receiving electric bows。
This component, known as the “bow of life” of the train, is like the “heart pacemaker”, extracting electrical power from the network of contact, driving the train wheel and lighting every lamp in the car。
However, such a core technology has long been monopolized by foreign firms in high-speed areas of more than 250 kilometres per hour。
In chengdu xindu district, chengdu young-goo orbit transport equipment ltd. Is attempting to open the technical gate。
In recent days, wang jianjun, chairman of the young-goon executive council, has revealed to dae-jing that they are rushing into autonomous development of electric bows at speeds of 250 km and above per hour and are launching a general attack on this “worst hard bone”。
As the country's few professional producers of electric bows, yonggyu has taken the lead in the south-west and has become the “hidden champion” of the divided track. And this time, they looked at the china express train。

Focus on the bow: research and development and life-cycle services
In the field of orbital traffic, electric bows fly as “wings” on the train to the ground, which is the core component of the train's access to electrical energy and whose performance directly determines the steady operation of the train。
The young-goon ocean corporation is located in chengdu's new orbit transport estate, and its core business is focused on the development and manufacture of electric bows and on life-cycle services, covering product development, production, maintenance and spare parts supply。
The company's representative's product received electric bows with a capacity of 1,500 units per year. Its products have achieved technological breakthroughs in key components such as lifting bow main springs, action cylinders, with longer operational life, lower frequency of overhaul and replacement costs。
Under stable operating conditions, the electric bows received in the yonggyu east ocean have a longer useful life cycle, which is also the result of years of operational practice by orbital transport operators。
In the field of electrical bowing, which has been the focus of intense attention, yong qiang, thanks to his outstanding technical skills, has become the only enterprise in the country with a dual national recognition of "specialty new" and "high-technology enterprises"。

Alternatives to national production: focus on high-speed access bow
As the only south-west operator for the electric bow system for orbital and electrical vehicles, yongjiang has become a qualified supplier to mainstream hosts such as the medium-car quadriage, the medium-car owner, tangshan, dalian and pompadi, with a cumulative capacity of over 2,700。
From chengdu metro 5, 6, 8, 19, 27, 30, municipal qianyang and dujiang mtr tourism lines, to the services of the metro outside tianjin, chongqing, shao xing, taizhou, wenzhou and jenan, the electric bows have been widely used in the orbital transport system throughout the country, and their operational maps have even been radiationed to overseas markets such as indonesia and thailand。
It is not difficult to see through market performance that the yangtze ocean has established itself in low-speed areas of rail traffic, such as subways and inter-city trains, but its ambitions are far beyond that。
Among the few key parts still to be imported, electrical bows were used during the journey of china's railing equipment industry towards a higher end. The wang jianjun revealed to dae-geong that “the eternal east ocean is breaking this pattern, and we are in the process of a technical attack”
It was described that young gui dongyang was developing a new type of electric bow at 250 km/h to cover the needs of city, inter-city and standard motorized units, with unique spring lifting devices and resistance bow structure to improve the stability of the bow network. In addition, packaging is designed to enhance autonomous protection and reduce wind-resisting noise。
Next, electrical bows for products and intelligence at 400 km per hour will be the main focus of the next effort. In the future, the yong-go series of products will cover more areas from subways to high irons。
Black-tech electric bow
The electric bow, which is the core part of orbital traffic, conceals many "black technology". To take the example of the electric bow, its "black technology" is mainly:
Seismic mitigation design for complex lines. Its high-speed electric bow bow is equipped with a third-stage buffer with a micro-vibration larynx airbone spring, suitable for a soft network of contact, self-regulating smooth transitions at the interface to ensure stable power supply。
Efficiency gains from the down-slipboard. The bow is designed to allow for more simple maintenance and local damage does not need to be replaced as a whole; precise control of static contact forces is required to reduce the grinding of skateboards and networks of contact and extend life。
Strong environmental adaptation. Adaptable to -40 °c ~ 70 °c wide temperature, partial models support 300 km/h high speed, rated currents up to 1600a, which can stabilize lifts and drop bows at different pressures and fit multiple scenarios。

Young gui's layout in tawakawa: orbital traffic, new energy electric vehicles
Young qi dongyang is only one of the industrial blocks where yong qi (300351. Sz) is located in kawakawa。
Its headquarters is located on the zhejiang ceiling and is a national high-technology enterprise focusing on various types of electrical connectors, connector components and sophisticated intelligence products, which was listed at the deep point in 2012。
At present, the permanent utility is centred on connector technology, which forms a cluster of three industrial blocks: orbital traffic and industry, vehicle-borne and energy information, and special equipment. It forms a layout of seven major products, including connectors, door systems, boosters, trans-channels, axle signal systems, electric bows and batteries。
As early as 2008, yong-go had set up sichuan young-goe technology ltd. In sumiyang, and later developed into a state-level specialized new “small giant” enterprise。
In addition to taking over the advantages of the “old-school” track transport industry, sichuan young-goo has now established cooperation with companies like chire and biadi。
Sichuan young-goo released the lts large power charger in 2023, covering the national/european/american interface and international certification through ce, tÜv, etc. The second phase of the project, which was launched in 2025, resulted in 2. 7 million units of annual photovoltaic connectors, which are among the top 10 brands of recharging guns in china。
Of concern is the continued increase in strategic investment in yong-yo dong-yo and the completion of the $14 million replenishment by the end of last year, which rose to 66. 6 per cent, reflecting its full confidence in and support for the future development of yong-yo-yong。

Chengdu: city of advanced construction of orbital traffic throughout the country
The electric bow is a cross-section of china's high-end orbital traffic manufacturing competition and a microcosm of the development of the chengdu orbital transport industry。
In the early stages of the development of the orbital transport industry, chengdu began to pry the industrial chain and introduced precisely key supporting enterprises, including electric bows, in an attempt to fill indigenous gaps。
As a priority, yangtze has launched a business venture, and has witnessed the development of hundreds of billions of class industrial clusters in chengdu's orbital transport equipment industry as strategic and emerging clusters at the national level。
Today, chengdu's trajectories begin with a complete industrial chain of scientific and technological research and development, survey design, engineering, equipment manufacturing and transport services. The data show that the chengdu track transport industry chain has earned more than $440 billion, making it one of the 10 trillion industry clusters。
Chengdu also continues to maintain a steady urban track traffic “fourth city”. According to the ministry of transport and communications, urban orbital traffic operating data summary 2025, by the end of 2025, chengdu was 719. 53 km in length, after beijing, shanghai and guangzhou。
At present, all of them are building and operating more than 850 kilometres. The growth of the orbital transport industry is being driven by the expansion of chengdu orbit traffic。
The plan of action for the operation of the chengdu orbit transport industry clearly states that the continuous upgrading of vehicle equipment, engineering equipment “two major manufacturing capabilities”, the acceleration of the construction of the scientific conversion of orbital traffic, the testing and testing, the operation of the three service systems for the protection of the “three service systems”, the construction of the city of advanced orbital traffic manufacturing, the city of high-end services, and the conversion of innovative sources and results into highlands。
Line 30 of chengdu metro
Looking at the country as a whole, the orbital transport equipment industry cluster has developed a pattern of “more than one size”, with hunanjia, shandong qing island, jilin changchun and sichuan sung constituting the first team。
Of these, ji cai, known as the “cradle of china's electricity machines”, has a concentration of more than 400 companies on the chain, with a local support rate of more than 80 per cent, with industry at the top of the world; aoshima, the leader of the quartet, has a value of $150 billion in value of industrial chain production in 2025; changchun, with its long-term long-distance passenger base, has a domestic market of more than 35 per cent and its products have been marketed for more than 20 countries and regions; and all, with more than 570 upstream and downstream enterprises, with a local support rate of over 75 per cent, has become the high ground for the western track transport equipment industry。
It has been argued that, in the urban industry cluster game, cheng should continue to strengthen support for tradable equipment and supporting enterprises, helping them to break through technological bottlenecks, expand the application landscape and move the industrial chain to higher levels of capacity。
With a view to the future, as the world's largest rail network operator and leader in the area of electrification, the construction of china's rail traffic will continue to increase, providing extensive market space for the manufacture and maintenance of on-orbit equipment。
