An isolated phase busbar installation has a closed circulatory cooling system in which a deionization device is interconnected between the tubular enclosures of two isolated phase busbars of the installation between which air is caused to flow. The deionization device comprises an open-ended metal tubular housing which is connected to earth and which has, extending transversely across the bore and dividing the bore throughout its length into a plurality of passages, a plurality of mutually spaced metal sheets. Each metal sheet has a plurality of transversely extending convolutions at spaced positions along the length of the housing so that each passage follows an undulating path. The number of metal sheets and the number and amplitude of the convolutions of each sheet and the dimensions of each passage having regard to the volume and velocity of air flowing from the tubular enclosure of one of said busbars through the tubular housing to the tubular enclosure of the other of said busbars are such that no contaminants are carried by flow of air from one tubular enclosure to the other.
