How do high-speed rail wires cross cables?

1. The high-speed rail conductor is suspended by overhead contact line pillars on both sides; High-speed railway catenary is a special type of transmission line, which is erected along the railway line to provide electricity for electric locomotives. It consists of contact suspension, supporting device, positioning device, pillar and foundation. Contact suspension includes contact wire, messenger wire, carrier cable and connector. The contact suspension is erected on the pillar through the support device, and its function is to transmit the electric energy obtained from the traction substation to the electric locomotive.

2. High-speed railway, referred to as high-speed railway, refers to a railway system with high design standards and fast train running speed. Its concept is not limited to tracks, let alone trains.

3. High-speed rail has different regulations in different countries, different times and different scientific research fields. The Code for Design of High-speed Railway issued by China National Railway Administration defines high-speed railway as a newly-built passenger dedicated railway with a design speed of 250 km/h to 350 km/h and running the standard gauge of EMU trains. China's National Development and Reform Commission defined China's high-speed railway as a newly-built or existing railway with a speed of 250km/h or above, and issued the corresponding Medium-and Long-term Railway Network Planning Document, which included some track lines with a speed of 200km/h in the category of China's high-speed railway network.
