1. A method of coating an elongate, uncoated conductive element with a substantially continuous barrier layer, comprising:

  • winding the uncoated conductive element around a frame comprising spaced supports such that sections of the conductive element are positioned in contact with the two or more supports;

    depositing a barrier material on the conductive element to form the barrier layer;

    adjusting the relative position of the conductive element to the frame during deposition such that the sections of the conductive element are physically separated from the supports for a time that is sufficient to form the barrier substantially continuous barrier layer on the conductive element; and

    unwinding the coated conductive element from the frame.
