As a flexible cable, which is closely related to our life, how can we be laid, and what are the key points?
Correctly laid 5 main points
1. Flexible cable and heat pipe close or cross, if there are heat insulation measures, parallel and cross the minimum distance of 0.5m and 0.15m.
2. When the flexible cable, high voltage cable should be at the bottom of the low-voltage cable. If one of the cables is in the cross point of the 1m range or when the barrier is separated by a separator, the minimum allowable distance is 0.15m.
3. Flexible cable and building foundation of distance should be able to ensure cable buried outside the building bulk water; cable into the building should wear protective tube, the protective tube should be beyond the building bulk water.
4. Flexible cable and rail or road intersection should wear protective tube, the protective tube should extend rail or road outside 2m.
5. Directly buried in the underground cable and take the general device of ground between should be apart 0.15~0.5m; directly buried in the underground cable burial depth, the general should not be less than 0.7m, and should be buried in the frozen layer.
