Decoding of bus-bar symbols:
AIZ-X1-X2X3X4-X5UHL1,
AIZ- trade mark of bus-bar supports,
X1- nominal voltage in kV,
X2- index which shows the quantity of supported buses,
X3- index, which shows standard performance of bus-bar support (L- index of flat horizontal buses),
X4- width of aluminium bus,
X5- pollution degree by GOST9920,
UHL- pollution performance by GOST 15150, installation category by GOST15150.
Variants of performance are introduced in table 1.
