The Big Jump isolates the part of the circuit in which the intervention will be performed. In addition to allowing fewer users to go without power, preventive or corrective maintenance operations with Big Jumper have become more practical and efficient. The cart is capable of carrying a coil that must carry the cables that will be connected to the electrical networks. Each coil is equipped with four insulated cables, three phase cables and a neutral cable, each 300 meters long – with terminations. With the use of the Big Jumper equipment, interventions in the electrical networks can be made without interruptions and in a safe way.
