For example, as a lightning rod down the line of single-core high-voltage cable, you can use a set of metal pipe laying? Is not to consider some of the problems of electromagnetic induction?
Control cable and communication cable is not recommended to put together, mainly to consider the electromagnetic interference (interference communication), divided into the best, it is unconditional, control cables and communication cables need to use shielded cable to reduce interference. Grounding the cable on the bottom, safe electricity requirements.
From top to bottom if there are four layers of cable bridge or bracket in order: high-pressure power, low-voltage power, control cables, communications and computer cables, the best ground to the bottom of a layer. High-voltage cable load, easy to produce high temperature. If the laying in the lower, will have a great impact on the above low-voltage cable, the best on the upper, there is a little, high-voltage cables are generally steel armor layer, high mechanical strength, even without steel armor due to insulation Thick, bear the impact of the general object is also strong, for cable protection has some advantages.
