What is the maximum length of a sag section limited by?

The maximum length of a sag section is fundamentally influenced by various environmental factors, predominantly weather conditions and terrain.

Weather conditions play a critical role as they can change the physical behavior of the wire. For instance, in high winds or snow accumulation, the sagging characteristics are altered which may require adjustments to the length to prevent undue stress on the wire and associated hardware. Similarly, varying terrain can introduce significant variables, such as hosting structures at different elevations or slopes, which also affect the way a sag can be effectively managed.

When these two factors are taken into account, they ensure that the sag is maintained within safe limits to prevent failure or interference, thus defining the maximum permissible length of the sag section. In contrast, options that limit the maximum sag length to terrain only, deadends and angle structures only, or length of wire do not fully capture the multi-faceted influences that weather and terrain have on the sagging properties of wire.
