Abstract
A suspension bracket and apparatus for a bundle conductor has a yoke plate suspended at opposite sides thereof by respective insulator strings. To reduce high voltage gradients across the lowermost insulators of the strings, one or more of the sub-conductors is clamped to the upper side of the yoke plate between the strings. To facilitate "clipping in" of this sub-conductor by providing a temporary suspension connection between one of the strings and the yoke plate in order to allow that string to be uncoupled and thereby to allow the sub-conductor to be raised past the uncoupled string, the yoke plate is provided with a cylindrical opening extending transversely of the axis of that string by which the temporary connector can be connected to the yoke plate.
Claims11
A suspension apparatus for suspending a bundle of sub-conductors from a support, said suspension apparatus comprising:
- a suspension bracket comprising a yoke plate and defining a support plane;
- at least one pair of insulator assemblies, each having a major axis lying in said support plane, for suspending said suspension bracket at the lower ends of said insulator assemblies from said support;
- said yoke plate having first and second connection portions at opposite sides thereof connected to said insulator assemblies, respectively;
- a plurality of clamp means for securing said sub-conductors to said yoke plate;
- means pivotally connecting said clamp means to said yoke plate;
- at least one of said clamp means being located at the upper side of said yoke plate and between said insulator assemblies;
- and said yoke plate having attachment means associated with at least one of said insulator assemblies, in alignment with said major axis thereof, for attachment thereto of temporary suspension connector means for suspending said yoke plate upon uncoupling of said one insulator assembly.
A suspension bracket for suspending a bundle of cables with said suspension bracket extending in a direction transverse to said cables, said suspension bracket comprising:
- a generally planar body portion;
- said body portion including first and second connection means for connecting insulator strings having a major axis to said body portion for suspending said body portion from said insulator strings generally in the same plane therewith;
- said first and second insulator string connection means being spaced apart from one another in said transverse direction towards opposite sides of said suspension bracket;
- a plurality of cable clamps for securing said cables to said suspension bracket;
- pivot means securing said cable clamps to said body portion for pivotation transversely of said body portion;
- at least one of said cable clamps being located at the upper side of said suspension bracket between said first and second insulator string connection means;
- and
- said body portion further comprising attachment means for attachment thereto of temporary suspension connector means for connecting said body portion to one of said insulator strings at a position spaced from said body portion, each attachment means being in alignment with one of said insulator string connection means.
For use in suspending a bundle of sub-conductors from a support, the combination of:
- a suspension bracket comprising a generally planar yoke plate;
- at least one pair of elongated insulator assemblies connected to and suspending said yoke plate at the lower ends of said insulator assemblies, said insulator assemblies lying generally in the plane of said yoke plate;
- a plurality of clamp means for securing said sub-conductors to said yoke plate;
- means pivotally connecting said clamp means to said yoke plate;
- at least one of said clamp means being located at the upper side of said yoke plate and between said insulator assemblies;
- and attachment means on said yoke plate in direct alignment with at least one of said insulator assemblies for the attachment of temporary suspension connector means for suspending said yoke plate upon uncoupling of said at least one of said insulator assemblies.
A yoke plate for use in suspending a bundle of sub-conductors from a support, said yoke plate being generally planar and comprising first and second connector means for connecting first and second elongated insulator assemblies thereto, so as to lie in the plane thereof;
- a plurality of clamp means for securing said sub-conductors to said yoke plate;
- means pivotally connecting said clamp means to said yoke plate;
- at least one of said clamp means being located at the upper side of said yoke plate and between said connector means;
- wherein the improvement comprises:
- attachment means on said yoke plate in direct alignment with at least one of said connector means for attachment of temporary suspension connector means for suspending said yoke plate upon disconnecting of said at least one of said connector means from its respective insulator assembly.
