Overhead power line height rules need safety update, say farmers

Sparkingchip

The news report is behind a pay wall, but you'll get the gist of it, farm equipment is a lot bigger than it used to be particularly booms on sprayers and the like. 

So maybe it's time to increase the clearance of overhead electricity cables.

  • The article has the following statement:

    Lines that have up to 32 kV of power must have a minimum ground clearance of at least 5.2m,

    BS 7671 (Regulation 705.522) requires (and has for some time) BOTH 6.0 m height for suspended for LV cables (i.e. scope of BS 7671) in agricultural premises, and additionally all overhead lines to be insulated. Of course, cables in the scope of BS 7671 are well below the voltages being discussed.

    The cables in question are DNO/TSO cables, which are required to comply with Regulation 17 (and where specified Schedule 2) of ESQCR applies.

    Given this disparity, and the fact people are dying, perhaps it really is time for a debate on the issue.
