Claim:
1. A cross arm for supporting power distribution equipment, consisting of: an elongated support structure having an outer surface, an inner surface, a first end, and an opposing second end, wherein said inner surface defines a hollow inner core that extends from said first end to said second end of said support structure, wherein said support structure is made of a monolithic fiber-reinforced composite that extends from said outer surface to said inner surface, wherein said support structure is produced by a die/mold enabled pultrusion process; a protectant layer coating said outer surface, wherein said protectant layer does not provide structural support to said cross arm; a water-repellent material filling said inner core, wherein said water-repellent material does not provide structural support to said cross arm; and a first end cap sealing said inner core at said first end, and a second end cap sealing said inner core at said second end; wherein said support structure has a first pair of opposing sides defining a width dimension of said support structure and a second pair of opposing sides defining a height dimension of said support structure, wherein said outer surface of said support structure is rectangular in cross section; wherein said inner surface of said support structure defining said hollow inner core is curvilinear in cross section.
