Carbon-Nanotube Composite for Power Transmission Line & Inductor

The focus of this research project is possibilities of increasing the capacity of overhead power transmission conductors using Carbon Nanotubes (CNT). Current constraints to existing transmission conductors include: (i) high resistivity of the reinforcing steel strands; (ii) energy loss in the form of heat generated from this inefficiency; and (iii) and thermal expansion and increases the sag and length of the conductor. The unique properties of CNTs have generated much interest in their potential application to transmission conductors in the form of CNT-reinforced aluminum. A critical step in using CNTs within a new conductor is to develop a fabrication process that successfully transfers the properties of CNT to the matrix material of aluminum. A scrolling fabrication process has been developed, which may solve these challenges. Different strands of Al-CNT composite wires with different CNT concentrations will be fabricated. The effects of CNT concentration on the rated ampacity (i.e. the maximum current carrying capacity of the conductor before deterioration) will be examined.
