galvanized steel with cover Covers will be provided wherever mechanical protection is required According to the cable tray/Cable ladder/Conduit routing Drawings All calculation for specific cables are based on the installation method that has the most stringent cable sizing requirements in its cable route Voltage Drop 5.1 Voltage Drop Of Normal Operation State The voltage drop is calculated in percentage of the rated nominal voltage The Calculation checks whether the voltage drop is within the required voltage drop tolerance, namely 3% of rated nominal voltage Voltage drop is defined by: ∆U(V) = √3 × I × L(R cos ∅ + X sin ∅) Where:  R and X (_/km) are the resistance and reactance of a cable per kilometer; R apply for the cable resistance of 90℃ The converting process for resistance
