AIZ-10-SH
The bus- bar supports of outdoor application AIZ-10-SH are used for fixation of two aluminium tubular buses of rigid bus- bars at 10 kV voltage and current frequency to 60 Hz in open distribution devices of electric power stations and substations.
Bus-bar supports are made in climatic design UHL, category 1 according to GOST 15543.1-89 and GOST 15150-69, in which:
- altitude above sea level not more 1000 m;
- thickness of the crust of ice less than 20 mm;
- wind speed in glaze condition to 15 m/s;
- wind speed in the absence of glaze to 40 m/s;
- environment value of temperature of air + 40 °C;
- environment value of temperature of air - 60°C.
Environment not explosive, the content of corrosion-active agents must comply with the atmosphere requirements I and II according to GOST 15150-69.
Decoding of bus-bar symbols:
AIZ-X1-X2X3-X4-UHL1,
AIZ- trade mark of bus-bar supports,
X1- nominal voltage in kV,
X2- index, which shows standard performance of bus-bar support (SH- hinge fixation of aluminium tubular buse),
X3-conditional diameter of aluminium bus,
X4- pollution degree by GOST9920,
UHL- pollution performance by GOST 15150, installation category by GOST15150.
Variants of performance are introduced in table 1.
