(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
Safe maximum capacity of 10A conversion success rate of 2200W assured use, there will be no problem.
I am also 12 mouth, but no patch panels, patch panels are 24 mouth is too expensive to be fast 1000. 6 side panels side by side, plus 12 6 class module a total of . do not want any weak box. The weak box is weakly removed except for the 12U cabinet
220v electricity a kw current of about 4.5A, copper current density by 5A / mm ?, so 2000W electric water heater you choose 2.5mm ? copper line is enough.
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. If the signal line is laid directly on the bracket, the minimum distance is 750mm and 900mm.
