Live line working entails contact by linemen with energised conductors. Various techniques have been used, including the use of helicopters, aerial platforms, ladders and other methods to insulate the linemen from earth. Development of a robotic arm which can hold conductors while work is being done has considerably simplified the process and improved safety… (more)
“Barehand” and “hotstick” energised techniques, coupled with patented robotic arm technology, eliminate power supply interruptions during overhead transmission and distribution line maintenance works negating the cost of right of way acquisition, line switching, grounding and outage scheduling. Until recently only employed in the USA, these techniques have now arrived on local shores… (more)
