The supply pressure in Kazakhstan is 220 volts with the frequency of 50 Hz. Two-pin plugs (and respective sockets) of 2 types are in use:
- two round pins of light section (4,7 mm.) without ground connection (Soviet standard);
- two round pins of greater section (5 mm.) with ground connection or without it (European standard), which become more and more popular nowadays. You can easily buy the adapters for any types of plugs.
Nowadays power cuts happen quite seldom. One of the problems of the power supply (especially, in rural areas) is voltage oscillation. Accordingly, all the ultrasensitive electrical equipment should have stabilizing devices in order to prevent its possible damage.
