FIELD: electricity.
SUBSTANCE: invention relates to a connector's design and a method for connection of a high-voltage cable with electrical equipment, such as switching equipment in a power distribution substation. A self-locking unit is proposed for an end cable coupling, comprising a connector with a step. The self-locking unit comprises a ring, having a circumferential surface and multiple latches arranged on the circumferential surface. Each latch comprises a configuration, providing for displacement between a locked position, in which a latch is engaged with a step, and an unlocked position, in which a latch is disengaged from a step.
EFFECT: sliding ring has a configuration, which provides for displacement along a part of an external surface of a connector relative to a bearing ring, and comprises a groove, and a bearing ring is arranged on a ring connector, and has a configuration providing for limitation of displacement of a sliding ring, at least, in one direction.
