FIELD: transportation.
SUBSTANCE: device (2) for medium transportation with at least one channel (8) passing in axial direction (10), through which medium is directed, wherein corresponding channel (8) is surrounded by electrically conductive inner shell (38), which is connected to potential equalizing potential conductor (58), and to outer layer (32), wherein between channel (8) and outer layer (32) there is an electrically conductive outer shell (50), wherein outer shell (50) is connected to electroconductive potential equalizing potential conductor (56), wherein between channel (8) and outer shell (50) there is an electrically insulating intermediate layer (68), wherein intermediate layer (68) is made of heat-insulating material, wherein outer layer (32) is electrically conductive.
EFFECT: invention provides, at simultaneous termination possibility, better current-carrying capacity in explosive areas.
