China's first smart type-3 overhead line equipment was recently seen working at the Xiongan Station construction site of the 92.79-kilometer Beijing-Xiongan Intercity Railway.
The electric power, traction power transformation, overhead line system, communication, signal and supportive building construction of the railway were contracted by China Railway Construction Electrification Bureau Group Co., Ltd., a subsidiary of China Railway Construction Corporation Limited (CRCC).
The construction started in October 2018 and the smart equipment, which included a parameter examination and dropper calibration machine, was used to complete pillar assembly and bracket tube installation.
The basic location information of pillars and the BeiDou Navigation System information was imported to the pillar assembly equipment in advance, greatly improving safety.
The smart installation equipment, equipped with a mechanical visual guidance system and multi-degree of freedom-based actuating devices, is capable of installing electrical insulators and bracket tubes. Its efficiency level is an 80 percent improvement over that of traditional procedures.
The parameter examination and dropper calibration machine integrate such technologies as lasers, image fusion and high precision calibration, making it possible to demarcate height and stagger values of the overhead lines remotely as well as the accurate location of the dropper.
According to the company, electric and communication construction will be completed next and is now under equipment adjustment and static inspection.
The entire railway is scheduled to open to traffic by the end of this year.
