Application
DR 721 P is a reeling cable 0,6/1 kV used for spring cable and motor cable reels, hoists, transport systems, and farm vehicles with medium mechanical stress.
Outstanding features
- high winding and unwinding strength
- smaller outer diameter
- small cable weight
- corresponds to low voltage guideline 73/23/EWG CE
