CTOnews.com, May 20 (Xinhua) 22:30 local time on May 18, Indonesia, 27.5kV feeder lines of four traction substations of Yawan high-speed railway, Halim, Karawang, Varini and de Karoor, were closed one after another, and the catenary was successfully delivered, marking the realization of catenary power transmission on the Yawan high-speed railway line.

Officials pointed out that catenary power transmission is not only a "big test" for electrified railway catenary, but also the last important process before joint commissioning and joint test.

The traction power supply system of Yawan high-speed railway is designed and constructed in accordance with Chinese technology and Chinese standards. it is mainly composed of electric locomotive traction network power supply main system, driving equipment and production and life low-voltage power supply main system. Catenary system, transformer and power microcomputer protection system, AC / DC system and other core equipment are all made in China. It has the characteristics of unified technical parameters, unified equipment structure, unified types of parts and components, high service performance of key parts, easy maintenance, long service life, short protection delay, safety and reliability.

According to reports, the Yawan high-speed railway line is 142.3 kilometers long, with a total of 384.6 kilometers of catenary wires and four traction substations.

The high-speed EMU and comprehensive testing trains of Yawan high-speed railway are led by China Railway International Co., Ltd., a subsidiary of China National Railway Group Co., Ltd., to organize the design and manufacture of China Railway Qingdao Sifang Locomotive and Rolling Stock Co., Ltd., which is one of the members of the Chinese consortium of Yawan high-speed railway. This is also the first high-speed train exported in China.

According to CTOnews.com inquiry, the Yawan high-speed train adopts Chinese standards and is tailor-made for the Yawan high-speed railway, with a maximum operating speed of 350km per hour, four moving and four towing eight vehicles, relying on the advanced and mature technology of the Fuxing Chinese standard EMU, adapting to Indonesia's local operating environment and line conditions, integrating Indonesian local culture, and making adaptive improvements.

The Yawan high-speed railway, which connects Jakarta, the Indonesian capital, and Bandung, a famous tourist city, has a maximum operating speed of 350 kilometers per hour. Construction began in June 2018, with four stations on the line. After the completion of the project, the travel time from Jakarta to Bandung will be shortened from more than 3 hours to 40 minutes, which will greatly improve local traffic conditions and promote the development of industries along the route.

The Yawan high-speed railway is a landmark project of the "Belt and Road Initiative" construction and the practical cooperation between China and Indonesia, and it is also the "first order" for the overseas construction of China's high-speed railway system, all-element and whole-industry chain for the first time. After the completion of the project, the travel time from Jakarta to Bandung will be shortened from more than three hours to 40 minutes, which will help Indonesia's economic and social development, deepen cooperation between China and Indonesia, and promote the high-quality development of "Belt and Road Initiative". Is of great significance.
