Crews from LADWP are responsible for over 1,200 circuit miles of EHV DC (extra high voltage direct current) bulk power transmission lines running from Oregon and Utah to the city of Los Angeles. Both lines are 2312 conductor in either twin bundle or tri-bundle configuration. Every year, each of these important bulk power lines are shut down for a period of one full week to allow LADWP crews to maintain hardware, insulators and spacers. All of this work for spacing is done by hand in spacer carts, or "buggies", and not by helicopter. So, as a result, LADWP was keen on developing a cart rescue plan which would allow a second cart to be launched with rescue retrieval rope and hardware. These photos show some of the work done to facilitate this type of structure-based cart rescue. A manikin was used to simulate the victim being lowered from the conductor bundle still within the cart to the ground.
