Patent number: 10431967Abstract: A cable management system maintains separation laterally between a plurality of distinct phase conductors, each of which includes one or more insulated electrical cables. The system includes an electrically non-conductive brace having free ends, a length between the free ends, and predetermined conductor locations that are spaced apart from one another along the length. Apertures extend through the brace at the conductor locations. The cable management system further includes retainer straps and strap locks. Each retainer strap reaches around a corresponding conductor at one of the conductor locations on one side of the brace, and reaches further through a corresponding pair of the apertures to the opposite side of the brace. Each strap lock engages a retainer strap at one side of the brace to retain a corresponding conductor in place at the conductor location on the opposite side of the brace.Type: GrantFiled: August 4, 2017Date of Patent: October 1, 2019Assignee: Eaton Intelligent Power LimitedInventors: Michael Rowe MacGowan, Timothy Fair, Daniel Edward Hrncir, Robert Judson Burns
