Key Features
✓ Mobile substations are generally used to supply power to open cast mining dragline excavators.
✓ A robust construction capable of handling harsh conditions when lifted by a crane or dragged over open ground. This minimises both torsional and linear stresses on the equipment.
✓ M.V. enclosure is equipped with outdoor open bushings to allow for overhead lines connection.
✓ All controls and monitoring are carried out remotely in a segregated control room.
✓ A fence is integral to the skid to protect and prevent un-authorised access.
