Bridge 380V strong wire, and now put into the cable to the signal interference?
Power lines and cables can not be laid together. If the power cord and network cable together: . the transmission line is weak signal. Power lines inside the transmission is strong. Strong current through the wire will produce a magnetic field, the magnetic field will interfere with the weak line of the network cable, resulting in network cable signal is not normal, serious will affect the normal network cable communication. . there are security risks: If the power cord and cable are damaged, the two lines of copper core together. Strong current string into the network cable, will cause the connection of computers and other equipment burned. Serious can cause a fire.
As the cable has a variety of different models, insulation and conductor are different, so can not use tons to inquiry, but with the length of meters or 100 meters to inquiry. The price of the cable for each different specification is different
Heat shrink tube can be inserted into the cable, heat shrink tube is not much more than the cable on the line!
You first need to understand the cable model you need, and then ask the manufacturers how much money one meter, it is best to say that you need the total amount, there will be more concessions.
