Design Power (\( P_d \)):

\[ P_d = \frac{P_t \cdot SF}{LDF} \]

Where:

• \( P_d \) is the design power, in kilowatts (kW).
• \( P_t \) is the power to be transmitted, in kilowatts (kW).
• \( SF \) is the service factor, ranging from 1.0 to 2.5.
• \( LDF \) is the load distribution factor, ranging from 1.0 to 1.4.
