Support member for supporting electrical power lines
A support system for supporting power distribution or transmission lines includes a support pole having a first end and a second and a crossarm attached to the support pole, proximate the first end of the support pole. The crossarm has a first end, a second end and one or more side walls extending between the first and second ends of the crossarm. The side walls of the crossarm define an elongated interior space. The support system further includes an internal conduit formed in the interior space of the crossarm. The internal conduit extends along an axial direction of the crossarm. The internal conduit is made from insulative material.
1. A support member for supporting electrical lines, comprising:
an elongate crossarm having a first end, a second end opposing the first end, and a plurality of side walls extending between the first end and the second end, the first end, the second end, and the plurality of side walls defining an interior space;
an electrically insulative filling material within the interior space;
an internal conduit extending along an axial direction of the crossarm providing a passageway through the crossarm and the electrically insulative filling material.
2. The support member of claim 1 , further comprising at least one bushing spanning from a first of the plurality of side walls to a second of the plurality of side walls.
3. The support member of claim 2 , the at least one bushing member being positioned within the crossarm to align the internal conduit in place.
4. The support member of claim 2 , the at least one bushing member including a plurality of bushing members positioned alternately along the length of the crossarm.
5. The support member of claim 1 , the elongate crossarm being formed from structural polymeric material.
6. The support member of claim 1 , the internal conduit being formed from the same integral material as the crossarm.
7. The support member of claim 1 , the internal conduit being formed from an electrically conductive material.
8. The support member of claim 1 , the internal conduit being an electrically conductive member having two or more ends extending outside of one or more of the first end, the second end, and the plurality of sidewalls for attachment to one or more wires.
9. The support member of claim 1 , further comprising one or more endcaps located at a plurality of openings defined by the internal conduit.
10. The support member of claim 9 , the plurality of endcaps including apertures for accessing the internal conduit.
11. The support member of claim 1 , further comprising a wire fed through the internal conduit.
12. A support member for supporting electrical lines, comprising:
an elongate crossarm having a first end, a second end opposing the first end, and a plurality of side walls extending between the first end and the second end, the first end, the second end, and the plurality of side walls defining an interior space;
an internal conduit located within the interior space and extending along an axial direction of the crossarm providing a passageway through the crossarm;
one or more endcaps located at a plurality of openings defined by the internal conduit, the endcaps including apertures located at the internal conduit for accessing the internal conduit for insertion of a wire through the passageway.
13. The support member of claim 12 , further comprising a wire fed through the internal conduit.
14. The support member of claim 12 , the elongate crossarm being formed from structural polymeric material.
15. The support member of claim 12 , the internal conduit being formed from an electrically conductive material.
16. The support member of claim 12 , the internal conduit being an electrically conductive member having two or more ends extending outside of one or more of the first end, the second end, and the plurality of sidewalls for attachment to one or more wires.
17. A support member for supporting electrical lines, comprising:
an elongate crossarm having a first end, a second end opposing the first end, and a plurality of side walls extending between the first end and the second end, the first end, the second end, and the plurality of side walls defining an interior space;
an internal conduit extending along an axial direction of the crossarm providing a passageway through the crossarm;
the internal conduit defining at least one opening in a respective one of the plurality of sidewalls, the opening corresponding to a proximate location of one or more of the electrical lines.
18. The support member of claim 17 , further comprising one or more endcaps located at a plurality of openings defined by the internal conduit.
19. The support member of claim 18 , the plurality of endcaps including apertures for accessing the internal conduit.
