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.
Claims22
A neutral section for use with an overhead railway conductor line, the neutral section isolating a first conductor from a second conductor, the neutral section comprising:
- an elongate insulating body comprising:
- a generally planar contact section extending along the length of the insulating body and having a first height;
- a spine integrally formed on a top side of the planar contact section, the spine extending along the length of the insulating body and having a second height;
- and
- first and second connection member housings, each connection member housing integrally formed with the spine and the planar contact section and disposed at a respective end of the insulating body;
- wherein the combination of the first and second heights defines an insulating body height,
- wherein the profile of the neutral section is designed such that, when placed in use, the neutral axis of the neutral section is closely aligned with the neutral axes of the first and second conductors connected to respective ends of the insulating body, and
- wherein the insulating body height is chosen such that the stiffness and the dynamic mass of the neutral section, in both the vertical and horizontal planes, substantially match the stiffness and the dynamic mass of the first and second conductors connected to respective ends of the insulating body.
