Q:(4-20MA signal line, RS485 communication line, there are a few 220v power cord) can not be placed in the electrical cable trench, the design specifications are not required to add the problem: electricity is mainly 380V motor cable more many

In the safety reasons, and to facilitate the high-voltage cable from the bottom into the pump room, power distribution room and other facilities underground cable trench. Up and down no request, distance requirements, not less than 500 bar. Sub-bridge laying is not required, but in accordance with the following requirements to understand the instrument signal trunking in the top will be better. SHT3521-2007 petrochemical instrumentation engineering construction technical regulations p41 does not have to be laid in the above statement, but there is a minimum distance of the provisions, such as the signal line is laid in the steel pipe or covered with the pool slot, 250V, 50A power cable load , The minimum distance of 450mm; 440V, 200A power cable load, the minimum distance of 600mm.
