1. Keep a distance of 2m when the mine cable is installed in parallel with the heating pipeline, and keep 0.5m when crossing.
2. When the cable is installed in parallel or across other pipes, a distance of 0.5m must be maintained.
3. When the cable is directly buried, the depth of the 1-35kV cable shall not be less than 0.7m.
4. When the cables of 10kV and below are installed in parallel, the mutual clear distance shall not be less than 0.1m, 10-35kV shall not be less than 0.25m, and the cross distance shall not be less than 0.5m.
5. The minimum bending radius of the cable must not be less than 15D for multi-core cables and 20D for single-core cables (D is the outer diameter of the cable).
