keyboard_arrow_downApplication
Flexible cable is intented for application in mines with methane pits. It is used for supplying combine machines and for machines at preparation and opening of sites. Apart from the application of cable controller, it is possible to achieve two control circles, for example for the control of conveyor and of combine harvester. During operation cable is in continuous movement, exposed to mechanical strains and it satisfies severe working conditions. Construction of EpN 63 cable is intended for laying in cable chain where bending radius is 2.5 DD and it can sustain 5000 single bending cycles according to internal regulations of ELKA. Construction of EpN 63 (S) cable is intended for supplying combine harvesters without cable chain where cable is drawn by the machine and thereby exposed to great tensile forces with bending and twisting. Permissible bending radius is 5 D, with 5000 single bending cycles (D=external cable diameter)
