The metric for a superconducting cosmic string with constant momentum has been calculated analytically and numerically using the full Einstein field equations. We show that the string metric has mixed components, which for heavy strings (ηφ~1018 GeV) describe a spacetime with exotic properties. In the string spacetime particles are deflected (in the z-direction) as they approach the string, effectively isolating the defect from the outside Universe. The inclusion of gravity into models of charged strings and vortons is expected to have significant cosmological implications.
