High-speed railway section power cable well with strong and weak cables physically isolated

The utility model discloses a high-speed railway section power cable well with strong and weak cables physically isolated. The high-speed railway section power cable well comprises a cable well body and section cable grooves located in openings of the side walls of the two ends of the cable well body in the line direction. The four corners of the cable well body are oblique angles, the included angles between the oblique edges of the oblique angles and the interval cable grooves are 140-155 degrees, and concrete single-hole cable grooves are formed in the cable well body and close to the line side. According to the utility model, the bending radius requirement during interval cable laying is met, physical isolation of a power cable and a weak current cable is realized, and the danger that the cable on one side is on fire and the normal operation of the cable on the other side is influenced is effectively prevented, so that the accident expansion and the influence on the normal operation of a motor train unit
