Avoid Cable Strikes with Cable Location Tools

Avoid Underground Cable Strikes through Cable Location & Detection Tools  

This underground cable damage and strike incident occured during the installation of a street lighting feeder pillar with a private electricity supply. The operatives drove earthing spikes into two 33kV underground power cables - one 33kV cable was live being used as an 11kV supply and the second cable was temporarily out of service. The damage to the buried high voltage cables was not discovered immediately - weeks later the 33kV cable switched out causing significant electric power disruption to customers. As can be clearly seen the earth spikes had to penetrate not only a metre of ground but also the concrete tiles protecting the 33kV high voltage cables.
 

Conclusion
To avoid this type of cable damage a cable location or detection tool should always be used in conjunction with utility records.
