  • Neutral section insulator
    Patent number: 7740117
    Abstract: In a neutral section (1) for use with an overhead railway conductor line, which neutral section (1) is disposed between the ends of the conductor line when in use and comprises an insulator (10) to isolate the ends of the conductor line from each other, the neutral axis of the neutral section (1) being such that when the neutral section (1) is in use the neutral axis is aligned closely with the neutral axis of the conductors on its either side and the height of the insulator (10) is chosen so that the stiffness and the dynamic mass of the neutral section (1) closely match those of the conductors on its either side in both the vertical and horizontal planes.
    Type: Grant
    Filed: May 21, 2009
    Date of Patent: June 22, 2010
    Assignee: Multiclip Company Limited
