What are the distribution voltages rated at between 400kV to 240V in Great Britain?

In Great Britain, the distribution voltages are typically standardized at several levels, with the highest being 400 kV for transmission. The common distribution voltages below this level include 132 kV, 66 kV, and 33 kV for primary distribution, followed by secondary distribution voltages of 11 kV, 6.6 kV, and finally down to 400 V for three-phase supply and 230 V for single-phase supply used in residential settings. These voltages are part of the UK's electrical system to ensure efficient transmission and distribution of electricity.
