Trial of a new overhead line (OHL) repair process, which is performed fully from the ground. The new method involves using a specialist joint in combination with a pulley system to reconnect and lift the damaged conductors.
In order to minimise the impact storms have on customers, a new temporary overhead line repair process that can be performed fully from the ground is to be trialled. The new method involves using a specialist joint in combination with a pulley system to reconnect and lift the damaged conductors. First, one side of the broken conductor is extended to ensure that both ends can be pushed through the specialist joint. A pulley arrangement is then connected to both sides of the joint using OHL accessories like preforms and snap shackles. Finally, the rope connected to each pulley system is pulled on by a person which gradually lifts the conductor back to its original place. Using extendable OHL tools all excess conductor is cut off and both pulley systems are taken down.
In order to ensure the successful implementation of the emergency joint:
