Abstract: An apparatus includes a strength member including a core formed of a composite material, and an encapsulation layer disposed around the core. A conductor layer is disposed around the strength member. A coating is disposed on the conductor layer. The coating is formulated to have a solar absorptivity of less than 0.5 at a wavelength of less than 2.5 microns, and a radiative emissivity of greater than 0.5 at a wavelength in a range of 2.5 microns to 15 microns, at an operating temperature in a range of 60 degrees Celsius to 250 degrees Celsius. The coating may have an erosion resistance that is at least 5% greater than an erosion resistance of aluminum or aluminum alloys.
