How to Design an Underground Cable Network for Power Distribution

Underground cable networks are widely used for power distribution in urban and industrial areas due to their reliability, safety, and aesthetic advantages over overhead lines. The design of an underground power cable network involves several critical steps, including load assessment, cable selection, laying techniques, and protection considerations. This article provides a comprehensive guide on designing an efficient underground cable system with detailed calculations and examples. Step 1: Load Assessment and Network Planning Load Calculation The first step in designing an underground power distribution network is to determine the total load demand. This involves: Identifying the connected load (in kW or MW) Determining the demand factor and diversity factor Calculating the maximum demand Example: Suppose a residential area requires a power supply with the following load distribution: 500 houses, each with a connected load of 5 kW Demand factor = 0.7 Diversity factor = 1.5 Maximum demand = (Tot…
