The overhead contact line pillar is the main load-bearing equipment of the overhead contact line, and it is also an outdoor power supply support device without backup. It is often affected by severe weather such as ice, snow, rain, fog, etc. Once it encounters a fault or accident, it will directly affect the operation of the train. Therefore, the key to the overhead contact line pillar is the safety and reliability of its structural load-bearing. In addition, the overhead contact line pillar should also consider the simplicity and lightness of the structure, good corrosion resistance, and reasonable material utilization, and require ease of construction and operation maintenance.

The structure of the overhead contact line pillar should be considered to be simple and lightweight, with good corrosion resistance and reasonable material utilization
