1 No armored cable in the house Ming Fu, when the level of laying, the ground to the interval should not be less than 2.5 meters; when laying straight, the ground to the interval should not be less than 1.8 meters.
When you can not meet the above requirements should avoid mechanical damage to the cable approach; when the application is in the distribution room, motor room, equipment, and other special rooms, not subject to this constraint.
2 The same voltage of the cable side by side, the cable clearance should not be less than 35 mm, and should not be less than the cable diameter.
When the bridge, tray, and trunking are laying, are not subject to this constraint. 1 kV and below the power cable and control cables and more than 1 kV power cable should be separated laying.
When the parallel application, the net distance should not be less than 150 mm.
3 The net space between the cable and the heat pipe should not be less than 1 meter.
When the clearance is less than or equal to 1 meter, the insulation method should be adopted.
And non-thermal pipelines should not be less than 0.5 meters, when the net distance is less than or equal to 0.5 meters, should be in the pipeline near the cable section, and from the two ends of the extension of not less than 0.5 meters within the cable section On the adoption of the way to avoid damage to the cable by mechanical means.
