The range of a high-voltage (HV) transmission line depends on several factors, such as the voltage level, the type of transmission (AC or DC), and the type of conductors used.
Here are some general guidelines for HV lines:
1. **Low Voltage HV Lines** (Typically 69 kV to 138 kV):
- These can typically cover distances up to **100–150 miles** (160–240 km).
2. **Medium Voltage HV Lines** (Typically 220 kV to 345 kV):
- Can cover distances around **150–300 miles** (240–480 km).
3. **High Voltage HV Lines** (Typically 500 kV to 765 kV):
- These lines can cover even longer distances, generally up to **500 miles** (800 km) or more.
4. **Ultra High Voltage (UHV) Lines** (Typically 1000 kV and above):
- These can cover much greater distances, even over **1,000 miles** (1,600 km) depending on the specific infrastructure and technology.
In practice, the exact range depends on factors like the geography, climate, the capacity of the line, and whether the line is operating in an alternating current (AC) or direct current (DC) mode. HVDC lines, for example, are more efficient over long distances compared to traditional AC lines.
Is there a specific voltage level you're asking about? Or perhaps a particular setup or scenario you're considering?
