Bus-bar supports for end fixation of aluminium tube of rigid bus-bar .. Product #: based on 0 Reviews Regular price: $0.00 $0.00

AIZ-110-K

 

The bus- bar supports of outdoor application AIZ-110-K are used for aluminium tubes supporting of rigid bus- bars at 110 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:

Bus- bar supports are made on the basis of polymer rod insulators which are intended in applying in bus-bar supports. There was used special design and construction for the bus-bar support. Factory does not recommend applying the standard insulators as insulated supports of distribution devices. Bus-bar supports AIZ are applied for opened distribution devices of electric power stations and substations of alternative currents with 6-220 and kV voltage 50 Hz frequency. Insulators are made in accordance to IEC 62231standard and Technical specifications TS3494-005-59116459-0 ,,Bus-bar supports for the 10-220 kV voltage”.
 
The monolithic core of insulator of bus-bar support eliminates possibility of internal discharge and breakdown, unlike tubes filled with foam, as well as leakage of current in internal cavity and on the wall of tube as consequence of condensation in contrast to hollow tubes. Flanges of bus-bar supports are made from cast high-strength aluminium alloys. Absence of welds in flanges allows applying insulators in the conditions of low temperature in Siberia.
 
Advantages of bus-bar supports AIZ-110-K....UHL1
 
Thanks to the silicone adhesive coating on the insulating body of the bus-bar support useful service life- 30 years; high firmness to influence of acids and alkalis, to an ultra-violet exposure; resistance to erosion and tracking; high hydrophobic properties; light weight; more resistible for acts of vandalism; ensures safety conditions even during installation and exploitation works.
 
The bus-bar support DOES NOT FALL TO THE GROUND in condition of overloads on bend, it just curves. That’s why it eliminates possibility of personal injury.
