China's first overseas high-speed rail construction project: Jakarta-Bandung high-speed rail comprehensive contact network power transmission successful

News on May 19, according to official news from China Railway, the Jakarta-Bandung High-Speed ​​Railway successfully achieved full line power transmission through the catenary network at 22:30 local time on May 18 (23:30 Beijing time) in Indonesia, marking the completion of the project. Important milestones achieved. The Jakarta-Bandung High-Speed ​​Railway is the first full-system, all-factor, and full-industry chain project of China's high-speed railway constructed overseas. Its traction power supply system is designed and constructed using Chinese technology and standards to ensure the safe operation of high-speed trains.

ITBEAR technology information revealed that the construction of the Jakarta-Bandung high-speed rail has begun in June 2018. The high-speed rail will connect Jakarta, the capital of Indonesia, and Bandung. The Jakarta-Bandung high-speed railway has a total length of 142.3 kilometers, a total of 384.6 kilometers of catenary wires, and four traction substations. The successful realization of power transmission to the entire line of catenary network is the last important process before the joint commissioning and commissioning of the Jakarta-Bandung high-speed railway, and it is also an important test for the electrified railway catenary network.

Catenary power transmission converts the high voltage of the local power grid along the high-speed railway into 27.5 kV single-phase power frequency alternating current, and transmits it to the high-speed railway line through the catenary. High-speed rail trains provide power. The Jakarta-Bandung high-speed railway's core equipment such as the catenary system, substation and power microcomputer protection system, and AC and DC systems are all made in China. They have unified technical parameters, unified equipment structure forms, and unified parts types, ensuring the equipment's reliability. Easy maintenance, long service life, short protection delay, safe and reliable.

The Jakarta-Bandung High-speed Railway is the first high-speed railway in Southeast Asia with a maximum design speed of 350 kilometers per hour. Once completed and opened to traffic, it will greatly shorten the travel time between Jakarta and Bandung, from more than 3 hours now to 40 minutes. It provides fast and convenient passenger transportation between the two cities. This will actively promote economic and personnel exchanges between the two places and promote inter-regional exchanges and cooperation.

The successful realization of full-line catenary power transmission on the Jakarta-Bandung high-speed railway is not only a milestone in China’s overseas construction of high-speed railways, but also injects new vitality into Indonesia’s transportation development. The smooth progress of this project will set an example for cooperation between China and Indonesia in the field of infrastructure construction and lay the foundation for more international cooperation projects.
