Due to the high current flowing through the power cable
that warms the cable and its temperature rises so we use
ladder tray for power cable and the temperature of the
power cable can be exchanged with the surroundings.
We cant use ladder tray for control cables because the
control cables have high bending capability ( flexibility)
which is dropping belly ( belly bend downward ) and the
control cables temperature is always near the ambient
temperature and the perforated cable tray is suitable.
