Replacing wooden & concrete poles
Reduce the frequency of downed lines causing power outages
Introduction
Poles are the legs of Electrical Distribution body. So poles must be healthy, strong & rigid. In fact, a common person knows well the severity of fallen electric overhead line pole.
Poor management due to lack of information about pole condition may over time lead to a substantial accumulation of costs due to repairs and customer interruption costs.
Reasons of Pole Failures
The main damage that wood poles are subjected to is the Degradation of mechanical strength due to wear and decaying of the wood and to the influence of insects and woodpeckers.
Decaying takes place mainly in the ground level zone where humidity, fungi, bacteria and pollutants may penetrate inside the pole through the natural cracks in the wood or through the passages created by insects.
Decomposition of wood by fungi or other Micro-Organisms resulting in softening and thus progressive loss of strength and mass.
preventive maintenance of electric overhead line poles:
Periodic condition monitoring of poles can prevent the unwanted power outages and higher risks and timely replacement of decayed poles avoids the highest corrective maintenance cost.
penetration measuring device (the best condition monitoring technic) :
measuring the number of rotations of a probe needed to penetrate a given distance indicates the condition of a given wood type (more rotations are needed to penetrate a given distance in harder wood than in softer wood). this is achieved by rapidly rotating a probe into the wood and measuring the rate of progress. any type of wood can be tested whether it is hard, soft, wet or dry. the results are stored on a computer for easy data collection and analysis. the data collected can be used to calculate the wood density.
"" we have proper liveline techniques to replace poles (wood or concrete) in liveline. our customers can enjoy uninterrupted power supply since pole replacement in liveline doest require shutdown of power lines ""
