Abstract:
1. An electrical cable shield for use in enhancing transmission of electricity over an electrical power line, comprising: an elongate sleeve having a longitudinal axis, a first end, a second end, and inner and outer walls extending between the first and second ends, the elongate sleeve being composed of at least one type of metal; a hollow interior defined by the inner wall of the sleeve, disposed along the longitudinal axis of the sleeve, and configured for insertion of an electrical power line therethrough; and a monomolecular carbon-based film formed by aligning elongated carbon-based molecules deposited on the inner and outer walls of the sleeve, the monomolecular carbon-based film providing a barrier that inhibits rust, friction and penetration of electrons emitted by corona discharge by an electrical power line positioned through the hollow interior of the shield.
