THE RELATIONSHIP BETWEEN DC 24V CABLE
DIAMETER AND THE TRANSMISSION DISTANCE
It is the recommended transmission distance when the cable diameter is fixed and the DC 24V
power consumption is below 10%. For the DC device, the max permission voltage power
consumption is 10%. The cables used in the following sheet are all copper wires. (the resistivity
of copper is
