On October 19, 2022, Indonesia time, the first overhead contact line of the Jakarto-Bandung high-speed railway was successfully erected in the section between the Karur Station and Padalang station of Indonesia's Jakarto-Bandung high-speed railway, marking that the first high-speed railway with a speed of 350 km per hour in Indonesia, contracted by China Railway, has entered the phase of professional core technology construction for electrification.

Thousands of high-speed rail

It is understood that the Jakarto-Bandung high-speed railway between Jakarta and Bandung is 142.3 kilometers of normal line, and 384.59 kilometers of catenary wires will be set up. The catenary system will use the "simplified" catenary equipment produced by China Railway Electrification Bureau. Compared with the conventional catenary device, "Jane series" catenary equipment bracket parts number decreased by 39%, reducing installation time by up to a third, the stability of the product manufacturing, parts of more integrated, effectively promoted the construction and work efficiency, operation and maintenance for standard equipment, intelligent identification parts failure provides the basis.

Overhead catenary wire erection

As one of the key control projects in the construction of high-speed railway traction power supply system, the catenary wire is vividly called the artery of high-speed railway line, and its construction quality directly affects the safety and stability of power extraction for high-speed trains. The Jakarta-Bandung high-speed railway in Indonesia adopts China-made constant-tension wire releasing vehicles for catenary wire erection. The equipment has high tension control accuracy and sensitivity, which can ensure the construction quality of catenary to meet the high-speed train operation.

It is understood that the communication, signal, power and traction power supply system equipment of the Jakarta-Bandung high-speed railway are all manufactured by Chinese enterprises, which is of great significance for promoting China's high-speed railway equipment to go global. When completed, the drive from Jakarta to Bandung will be reduced from more than three hours to 40 minutes. Editor/He Yuting
