Pultruded or extruded cross arm structures for utility poles
An pultruded or extruded cross arm structure for a utility pole, comprising an elongated hollow structure having an outer surface and an inner portion, the inner portion comprising one or more compartments configured to receive a wire.
1. A pultruded or extruded cross arm structure for a utility pole, comprising an elongated hollow structure having a length, an outer surface and an inner portion, the inner portion comprising one or more compartments configured to receive a wire, wherein each of the one or more compartments comprises a cavity inside the elongated hollow structure defined by the inner portion and one or more partitioning walls coupled to the inner portion.
2. The cross arm of claim 1 , wherein the one or more compartments extend the length of the elongated hollow structure.
3. The cross arm of claim 1 , wherein the one or more compartments further comprise a conduit located within the compartment.
4. The cross arm of claim 1 , wherein the inner portion further comprises insulating material.
5. The cross arm of claim 4 , wherein the insulating material is foam.
6. A pultruded or extruded cross arm structure for a utility pole, comprising:
a plurality of elongated hollow structures each having a length, an outer surface and an inner portion, each of the inner portions comprising one or more compartments configured to receive a wire,
wherein each of the plurality of elongated hollow structures are nested coaxially, and wherein each of the one or more compartments comprises a cavity inside the elongated hollow structure defined by the inner portion and one or more partitioning walls coupled to the inner portion.
7. The cross arm of claim 6 , wherein the one or more compartments extend the length of the elongated hollow structure.
8. The cross arm of claim 6 , wherein the one or more compartments further comprise a conduit located within the compartment.
9. The cross arm of claim 6 , wherein the inner portions further comprises insulating material.
