"the catenary pole is the prime supporting the whole power supply network. In order to ensure the accurate control of the pole, we repeatedly measure and correct each catenary pole in the construction, and accurately position it to ensure that the vertical deviation between the pole elevation and the subgrade and the rail does not exceed plus or minus 3 mm, so as to ensure the overall smoothness and structural stability of the catenary."
