Based on the calculated cable size, select a standard cable size that meets or exceeds the calculated value.
Based on the calculations, we select a standard cable size of 95 mm², which meets the requirements.
Cable Size (mm²) = (Load Current (A) x Cable Length (m) x Correction Factor) / (Voltage Drop (V/m) x Insulation Factor) mv cable sizing calculation excel
| Column A | Column B | Column C | Column D | | --- | --- | --- | --- | | Load Current (A) | Cable Length (m) | Ambient Temperature (°C) | Soil Temperature (°C) |
Use the following formula to calculate the voltage drop: Based on the calculated cable size, select a
Open a new Excel spreadsheet and create a table with the following columns:
Excel is a popular tool for performing cable sizing calculations due to its ease of use and flexibility. Here's a step-by-step guide on how to perform MV cable sizing calculations using Excel: Here's a step-by-step guide on how to perform
Cable Size (mm²) = (200 A x 500 m x 0.8) / (10 V/m x 0.9) = 88.9 mm²
Enter the values for the load current, cable length, ambient temperature, and soil temperature.
Cable Temperature (°C) = Ambient Temperature (°C) + (Load Current (A) x Cable Resistance (Ω) x Thermal Resistance (°C/W))
