You<>call<>materials able to conduct electricity with 100% efficiency
High Temperature Superconductors (HTS) are able, when cooled, to convey electrical current without loss of energy.
You call materials able to conduct electricity with 100% efficiency, meaning that no energy is lost during the electrical transmission, superconductors.
