Abstract
A spacer and/or spacer damper that provides for uniform spacing of horizontally bundled sub-conductors as well as enhanced heat dissipation is disclosed. More particularly, when applied to electrical transmission lines, the configuration of the spacer and/or spacer damper can include formed-wire outer rods which increase the conductor surface area thereby enhance heat dissipation. In other words, the outer rod assembly disclosed herein can provide for minimizing damaging effects of motion while enhancing heat dissipation of the underlying conductor and connector arm. Still further, the subject spacer or spacer damper can alleviate entangling of the sub-conductors most often caused by galloping, ice unloading, and fault currents.
Claims20
A transmission line spacing system, comprising:
- means for spacing a plurality of sub-conductors from each other;
- and
- means for maintaining a suitable operating temperature.
A method for achieving enhanced heat dissipation of an elongate conductor applied to a spacer, comprising:
- establishing a connection point that rigidly positions a first conductor from a second conductor;
- securing the first conductor at the connection point;
- and
- wrapping the connection point and a portion of the first conductor with a plurality of helically-wound outer rods, wherein the plurality of helically-wound outer rods increase conductor surface area.
A system that facilitates spacing, dampening and heat dissipation in a plurality of conductors, comprising:
- a first half-body frame having at least two ends or apexes;
- a second half-body frame having at least two ends or apexes, wherein the second half-body frame mates to the first half-body frame to establish a uni-body, wherein the uni-body is capable of rigidly spacing each of the plurality of conductors;
- a plurality of clamp arms each having an elastomer insert that is capable of gripping a conductor on one end, wherein the clamp arms are pivotably disposed between each end or apex of the first and second half-body frames;
- and
- a spiral-wound outer rod assembly that at least partially wraps a portion of each clamp arm as a point of grip to the conductor.
