NS166: Routine Overhead Line Inspection 

This Network Standard is Ausgrid's specification for the routine overhead line inspection

Scope

The routine overhead line inspection applies to all overhead pole lines on Ausgrid’s network. It extends from outside the boundary fence of substations (Bulk Supply Points, transmission and zone substations), to the point of attachment for low voltage customers. 

It does not include transmission tower lines, isolated poles in a predominantly tower line, equipment inside substation enclosures, Façade Mounted Aerial Bundled Cable, private mains or High Voltage Customer equipment. 

This standard does not include below ground or internal inspection of poles. These inspection tasks are described in detail in Ausgrid's Network Standard NS145 Pole Inspection and Treatment Procedures. 

The detailed scope of the inspection is included in Section 6. The lists provided are not exhaustive and are intended as examples of the types of items to be inspected. 

This standard describes the routine line inspection process. Any follow-up inspections performed by climbing a pole or using an Elevated Work Platform are corrective actions, and those procedures are not described in this standard.
