Calculate Size of Low Loss Header
Calculating the size of a low loss header is crucial for ensuring the safe and efficient operation of electrical systems. This calculator helps you determine the appropriate size based on your specific requirements.
How to Use This Calculator
- Enter the frequency, voltage, and current values.
- Select the insulation type.
- Click the “Calculate” button.
- View the results and chart below.
Formula & Methodology
The calculation is based on the following formula:
Cross-sectional area (mm²) = (Current (A) * Voltage (V)) / (Frequency (Hz) * Insulation factor)
The insulation factor is based on the selected insulation type:
- PVC: 0.6
- XLPE: 0.55
- LSZH: 0.5
Real-World Examples
Example 1: PVC Insulation
Frequency: 50 Hz, Voltage: 400 V, Current: 10 A
Cross-sectional area: (10 * 400) / (50 * 0.6) = 133.33 mm²
Example 2: XLPE Insulation
Frequency: 60 Hz, Voltage: 230 V, Current: 15 A
Cross-sectional area: (15 * 230) / (60 * 0.55) = 103.64 mm²
Example 3: LSZH Insulation
Frequency: 50 Hz, Voltage: 110 V, Current: 20 A
Cross-sectional area: (20 * 110) / (50 * 0.5) = 440 mm²
