Porcelain: Regular power line insulators are already built primarily from porcelain, that's a variety of ceramic content.
To have much more out of your wires, some are constructed with a stranded steel core, which is then wrapped with outer levels of aluminum to further improve its conductive potential. A fascinating characteristic of alternating present is that the current tends to vacation on the surface floor with the conductor as an alternative to uniformly throughout the total wire, which implies that wires of mixed metals could get each of the toughness of steel with Just about most of the conductivity of reliable aluminum.
