The Jakarta-Bandung High-Speed Railway completed installation of eight main transformers, marking the construction of traction power supply system entering a sprint stage, which will lay the foundation for power transmission across the entire line.

Self-developed and manufactured by China Railway Electrification Group Co, the eight transformers adopt advanced digital and intelligent monitoring technology to ensure that the system operate effectively in humid conditions along the Jakarta-Bandung High-Speed Railway, according to a report by people.com.cn on Wednesday.

The pace of construction along the Jakarta-Bandung High-Speed Railway has been accelerating. Welding of a total of 1,168 pieces of 500-meter-long steel rails needed for the 142.3-kilometer rail line was completed in January, laying a solid foundation for the completion of the track-laying in mid-February.

The railway, a landmark project under the China-proposed Belt and Road Initiative, connects Indonesia's capital city Jakarta and its fourth-largest city Bandung, which is also the capital of West Java province. 

With a design speed of 350 kilometers per hour, the railway built with Chinese technology will cut the journey between Jakarta and Bandung from more than three hours to around 40 minutes. And, the rail link is expected to enter commerical operation in June 2023.
