FIELD: electricity.
SUBSTANCE: invention is referred to electric equipment, in particular, to current-conducting cables of tubular structure of strip conductor wounded helically. The electric conductor of spiral geometry is made as a strip wounded helically around longitudinal axis; the longitudinal axis is placed outside limits of the strip cross-section, between turns there are gaps or a lock is pressed. The turns are arched in the central part towards the longitudinal axis. The conductor is equipped with outer Teflon coating made as a tube touching the conductor at spots of the lock location.
EFFECT: reduced weight at maintained operational parameters, improved flexibility, vibration resistance and capability to rapture-free elongation.
