NOTES:

1. Conduit and cable nearest R.P. Street Alignment only, shown.

3. Conduit depths shown are minimum and are dimensioned from finished ground line to top of conduit. Ramp down as required. Where conduits are normally laid at a depth greater than shown, that depth should be maintained.

4. Terminate LV and HV cable conduit in line, each end of pit.

5. Provide polymeric cable protection cover (and orange caution tape) over all cable not enclosed in conduit .6. Backfill cable pit with bedding sand.

2. Locations and depths shown to conduit ends allow minimum bending radius of cables to be achieved for connection to switchgear. Refer MATERIAL DATA drawings No. 5108 to 5111 for minimum bending radius of cables.

7. LV and HV cable locations shown at Padmounted Substation are illustrative only. Refer drawings No. 5128 to 5131 & 5160. Preferred sequence of construction is to install Padmounted Substation prior to cables.
