CABLE DUCT FOR ROUTING INSULATED POWER LINES Russian patent published in 1999 - IPC

FIELD: electrical engineering; insulated lines for aircraft and spacecraft. SUBSTANCE: cable duct has at least one hollow section with open cross-sectional area made of electricity conducting material whose inner wall is covered with safety coating. Holding strip, section locking and fastening members, and grounding means are placed inside hollow section. According to invention, there is longitudinal slot in hollow section which is locked with clamping section to hold in position power lines inserted in hollow section. Clamping section has holding strip and flexible deformed filler closed in sectional area. Holding strip is pressed by loose ends of external wall of hollow-section open area. Hollow section ends are free to mount at least one adapter and one tension relief device; one grounding member fastening unit is placed in front of the latter; one or more gaskets are fitted between grounding member fastening units. Adapter is sunk in hollow section to receive insulated power lines and functions to grip the latter and to connect ground to other safety system of insulated power lines or to provide connections to other power systems. EFFECT: provision for varying number of ducts, improved reliability of line fixation within duct, protection against vibrations and mechanical damage, improved grounding. 13 cl, 44 dwg
