How does it work?
Rather than drawing reactive power from the mine network, the Sandvik electrical current draw reducer unit fitted to a DD422i face drill rig provides this power element for all on-board drilling components. The advantages of using this on-board capacitor unit are detailed in the table below:
Advantages of using a Sandvik electrical current draw reducer unit on a Sandvik drill rig
- The reactive power draw from the mine network can be reduced up to 90% This combined with the new IE3 energy compliant electric motors means that the total need of electrical energy during drilling can be reduced up to 5% with the new DD422i
- The amount of energy losses in main electric lines and drill rig cables are reduced due to smaller cable sizes being used.
- A more stabilized electrical network is established due to fewer voltage drops, lower loads for transformers and cables
- Lowering of cable costs/more power available from the existing cables
The aim is to help our customers gain optimal drilling performance with a minimized requirement of electrical power from the mine infrastructure.
