So, is it possible/does it exist that 220V has three phases?

    \$\begingroup\$ Norway uses 230 V line-line with no neutral in three-phase configuration. There might be other countries with the same arrangement too. \$\endgroup\$ – winny Jan 15 '18 at 15:58

    \$\begingroup\$ Depends on what voltage you measure: The common (in Europe) 400V 3-phase configuration has 400V phase-to-phase voltage and 230V phase-to-neutral voltage each. \$\endgroup\$ – Turbo J Jan 15 '18 at 16:25

Any voltage can be supplied as three-phase. Various voltages are more popular in various parts of the world and in various usage situations. In the USA, 220-240 volt, three-phase has been used to some extent for small industrial installations, but 480 volts is much more popular for three-phase installations.
