ABSTRACT:
A welding cable has connectors at each end, and a plurality of electrical conductors extending through the cable from one connector to the other. An insulating element includes a tubular outer wall, and a plurality of wall portions extending radially in respective directions from the central portion to the outer wall, each conductor being disposed in a passageway defined by a respective pair of adjacent radial wall portions and a portion of the outer wall. The connectors at the ends of the cable facilitate a flow of cooling water through the passageways in the insulating element. The insulating element extends through a pair of axially spaced, tubular cover portions, each of which has one end clamped to a respective connector. The other end of each cover portion is sealingly connected to a tubular swivel arrangement which facilitates rotation of the cover portions relative to each other and effects a fluid-tight coupling of the cover portions, the insulating element extending through the tubular swivel arrangement.
