keyboard_arrow_downApplication
Flexible cable is intended for application in mines with methane pits. It is used under application of adequate cable controller of high voltage network, where application of armoured cables isnt possible because of site removal, and those are pit transformer stations for supplying of excavations and preparation sites. At laying and removal during operation, banding radius is at least 5D (D = external diameter).
