keyboard_arrow_downApplication
Flexible cable is intented for application in mines with methane pits. It is used for all drives where usage of cable controller and remote-control usage are indicated. Permissible bending radius at removal during operation is 2.5D, at what radius the cable can sustain 5000 single bending cycles without inner damages (D=external cable diameter). Construction 3x6+2,2,5+6mm2 is not according to HRN and it has been specially developed for drilling machines. EpN 62 construction enables application of cable controller and drilling machine control.
