What are the requirements for cable laying distance?
Buried cables are strictly parallel to or above the industrial pipe
Where, when the cables cross each other, the high voltage cable should be placed under the low voltage cable Special circumstances should be implemented in accordance with the following provisions: 1) l0kV or more between the power cable and the control cable or between the use of different departments of the cable, when the cable through the pipe or separated by a partition, the parallel clearance can be reduced to 01m, 2) Between the power cables, between the control cables and between them, the cable between the different use departments shall be reduced to 025m3 when the cable is perforated or separated by a partition before and after the intersection Cable and heat pipe (groove), oil pipe (groove), combustible gas and flammable liquid pipe (groove), thermal equipment or other pipe (groove), although the clearance to meet the requirements, but may damage the cable during maintenance Protection should be taken within the range of lm before and after the intersection When the cross distance can not meet the requirements, the cable should be inserted into the tube, the clearance can be reduced to 025m4) Cable and heat pipe (groove) And thermal equipment parallel, cross, should take thermal insulation measures, so that the temperature of the soil around the cable does not exceed lOC
The minimum distance between cables, cables and other pipelines, roads, and buildings shall be in accordance with Table 4-18
