Abstract: The transmission line is the electrical power system essential important composition, the electrical energy low loss does not have the loss transportation always is even the universal attention topic, its basic key to the situation is seeks new material substitution existing ordinary transmission line material. this article take the classical electron theory, the BCS theory and the strong couple gathers the theory to propose as the foundation: Take the free electron as the current carrier, take the electric insulation, the seal, the pressure resistance tubular new material provides circulates channel. this new material as the current carrier non resistance movement not to have the loss or the low loss in the electrical energy transportation, its resistance approaches 0. this kind of low loss transmission line new material realizes a low loss electric transmission new way, its significance is not inferior to the superconductor.
Key word: Transmission line material, ne
