An internal review of our underground cable conduits found that a majority of the Heavy Duty (HD) conduit bends have a bending radius below the minimum bending radius of our 11 & 33kV underground XLPE cables. As such, TS-085 has been updated to provide clear guidance in the correct application of the conduit bends and an opportunity to standardise process, providing a significant cost saving per annum.
|Outer Diameter||Stock Item Number||Bend Angle||Centerline Bend Radius||Change or Replaces|
*Denotes the conduit has been retained for use however, the application has been changed.
In addition, the following Light Duty bends have been removed from stock: NC5712, NC5720, NC5728, NC5714,
NC5722, NC5730, NC5733.
Any new design must specify the corresponding conduit as per Table 9 of TS-085 (Feb 2019 edition) for LV, 11kV and 33kV sized cables. Incorrect application may result in reduced life expectance for the cable. Further information on E-Drawings can be accessed via SA Power Networks. Technical Standards.
