Design and application of wire gaps at mining dragline crossings, coal loaders and unloaders

In the QR National electrified coal rail network, wire gaps have been required at dragline crossings to allow access for oversized mining plants and at coal loaders / unloaders to keep the coal loading and unloading activities away from the live high voltage overhead traction equipment. The interface between the pantograph of the electric locomotive and the overhead traction conductor wiring is a key consideration for the design of the wire gap as locomotives need to transit the gap. The design of the wire gap has been modified during the last few years to suit the new configuration of the electric train consist and to minimise the damage to the pantograph of the electric train. APC magnets play a vital role in minimising the arcing caused by the disconnection between the pantograph and the live overhead traction equipment.
