Frequently asked questions (FAQ)

Q: What is high-voltage transformer?

A: Transformers of 35-230kV are high-voltage transformers, those of less than 1kV are low-voltage transformers, those of 1-35kV are medium-voltage transformers, those of 230-1000kV are extra-high-voltage transformers, and those of greater than or equal to 1,000kV are ultra-high-voltage transformers.

Q: What is the high voltage transmission?

A: Ultra High Voltage (UHV) transmission lines are utilized to facilitate the transfer of substantial quantities of electricity across extensive distances. The principle underlying UHV technology is that higher voltage levels result in decreased energy losses during transmission. Furthermore, by enabling greater power capacity through a single line, the overall number of required transmission lines is minimized. This efficiency not only lowers project costs but also reduces the necessary rights-of-way for implementation.

Q: Q.What is the difference between high voltage and ultra high voltage?

A: AC transmission voltage levels are usually categorised as high voltage, ultra-high voltage and extra-high voltage. Internationally, it usually refers to the nominal voltage from 35kV to 220kV, 330kV to less than 1,000kV as ultra-high voltage, and 1,000kV and above as extra-high voltage.
