Abstract

Among other things, a spacer unit for spacing apart a bundle of cables is provided. The spacer unit comprises two or more spacer assemblies which are adjustable to provide for various sized bundle configurations and/or to provide for various degrees of spacing. Respective spacer assemblies comprise a housing apparatus and a modular frame. The housing apparatus couples to a clamping arm that clamps to a cable. The modular frame allows the spacer assembly to be coupled to other spacer assemblies to vary a configuration of a spacing unit, and is configured for selective rotation relative to the housing apparatus to facilitate altering a shape of the spacer assembly.

First claim

What is claimed is:

1. A spacer assembly for a power line, comprising:
a clamp arm for clamping the spacer assembly to the power line;
a housing apparatus defining an interior cavity, wherein the clamp arm comprises a base portion configured to be seated in the interior cavity to couple the clamp arm to the housing apparatus; and
a modular frame configured to couple the spacer assembly to a second spacer assembly, the modular frame comprising:
a substantially cylindrical base portion; and
an arm, wherein:
a first face of the substantially cylindrical base portion is configured to contact a first face of the housing apparatus and configured for selective rotation relative to the housing apparatus, and
the arm is configured to selectively couple the modular frame to a second modular frame of the second spacer assembly.

2. The spacer assembly of claim 1 , the first face of the housing apparatus comprising one or more splines configured for selective engagement with one or more splines of the first face of the substantially cylindrical base portion of the modular frame to inhibit rotation of the modular frame relative to the housing apparatus.

3. The spacer assembly of claim 1 , the modular frame comprising one or more apertures configured to accommodate a fastener for fastening the modular frame to a second modular frame of the second spacer assembly.

4. The spacer assembly of claim 1 , the modular frame configured to facilitate adjusting a distance between the housing apparatus of the spacer assembly and a second housing apparatus of the second spacer assembly.

5. The spacer assembly of claim 1 , the housing apparatus comprising:
a first housing member comprising a first male portion and a first female portion; and
a second housing member comprising a second male portion and a second female portion, wherein the first female portion is configured to be mated with the second male portion and the first male portion is configured to be mated with the second female portion to define the interior cavity.

6. The spacer assembly of claim 1 , comprising a second modular frame configured to couple the housing apparatus to a third spacer assembly, the second modular frame substantially in contact with a second face of the housing apparatus.

7. The spacer assembly of claim 6 , the second modular frame configured for selective rotation relative to the housing apparatus.

8. The spacer assembly of claim 6 , the second modular frame configured for selective rotation relative to the modular frame.

9. The spacer assembly of claim 6 , the second face of the housing apparatus on a diametrically opposite side of the housing apparatus relative to the first face of the housing apparatus.

10. The spacer assembly of claim 1 , comprising a dampening element configured to dampen vibrations on the power line.

11. A spacer unit for a power line, comprising:
a first spacer assembly comprising:
a first housing apparatus, and
a first modular frame configured for selective rotation relative to the first housing apparatus, the first modular frame comprising an alignment channel, wherein a first face of the first housing apparatus comprises one or more splines configured for selective engagement with one or more splines of a first face of the first modular frame; and

a second spacer assembly comprising:
a second housing apparatus, and
a second modular frame configured for selective rotation relative to the second housing apparatus, the second modular frame comprising an alignment pin for mating with the alignment channel.

12. The spacer unit of claim 11 , wherein an engagement of the one or more splines of the first face of the first housing apparatus with the one or more splines of the first face of the first modular frame inhibits rotation of the first modular frame relative to the first housing apparatus.

13. The spacer unit of claim 11 , wherein the alignment channel is sized relative to the alignment pin to facilitate a sliding motion of the alignment pin in the alignment channel.

14. The spacer unit of claim 11 , the first spacer assembly comprising a dampening element configured to dampen vibrations on the power line to which the first spacer assembly is coupled.

15. The spacer unit of claim 11 , the first spacer assembly comprising a third modular frame configured to couple the first spacer assembly to a third spacer assembly of the spacer unit.

16. A spacer assembly for power lines, comprising:
a clamp arm for clamping the spacer assembly to a power line;
a housing apparatus defining an interior cavity, wherein the clamp arm comprises a base portion configured to be seated in the interior cavity to couple the clamp arm to the housing apparatus; and
a modular frame configured to couple the spacer assembly to a second spacer assembly, wherein:
the modular frame is substantially in contact with a first face of the housing apparatus and configured for selective rotation relative to the housing apparatus, and
the first face of the housing apparatus comprises one or more splines configured for selective engagement with one or more splines of a first face of the modular frame to selectively inhibit rotation of the modular frame relative to the housing apparatus.

17. A spacer assembly for power lines, comprising:
a clamp arm for clamping the spacer assembly to a power line;
a housing apparatus defining an interior cavity, wherein the clamp arm comprises a base portion configured to be seated in the interior cavity to couple the clamp arm to the housing apparatus; and
a modular frame configured to couple the spacer assembly to a second spacer assembly, wherein:
the modular frame is substantially in contact with a first face of the housing apparatus and configured for selective rotation relative to the housing apparatus; and
the modular frame comprises one or more apertures configured to accommodate a fastener for fastening the modular frame to a second modular frame of the second spacer assembly.

18. A spacer assembly for power lines, comprising:
a clamp arm for clamping the spacer assembly to a power line;
a housing apparatus comprising:
a first housing member comprising a first male portion and a first female portion; and
a second housing member comprising a second male portion and a second female portion, wherein:
the first female portion is configured to be mated with the second male portion and the first male portion is configured to be mated with the second female portion to define an interior cavity, and
the clamp arm comprises a base portion configured to be seated in the interior cavity to couple the clamp arm to the housing apparatus; and

a modular frame configured to couple the spacer assembly to a second spacer assembly, the modular frame substantially in contact with a first face of the housing apparatus and configured for selective rotation relative to the housing apparatus.

19. A spacer assembly for power lines, comprising:
a clamp arm for clamping the spacer assembly to a power line;
a housing apparatus defining an interior cavity, wherein the clamp arm comprises a base portion configured to be seated in the interior cavity to couple the clamp arm to the housing apparatus;
a modular frame configured to couple the spacer assembly to a second spacer assembly, the modular frame substantially in contact with a first face of the housing apparatus and configured for selective rotation relative to the housing apparatus; and
a second modular frame configured to couple the housing apparatus to a third spacer assemb
