END CONNECTION ASSEMBLY Russian patent published in 2012 - IPC H02G15/34 

FIELD: electricity.

SUBSTANCE: end connection assembly contains a cable end section forming a central longitudinal axis and containing end parts of N electric phases, the neutral conductor end parts and a surrounding thermal insulating shell intended to contain the cooling fluid. The each end part of the N electric phases and the end part of neutral conductor contain at least one electric conductor and are placed inside the cable concentrically around the core frame. Phase 1 is placed closer to the centre while Phase N is placed in the cable point that is most distant from the centre. Phase N is surrounded by the neutral conductor. Between neighbouring electric phases and between Phase N and the neutral conductor one places electric insulation. Each end part of the neutral conductor and the electric phases contains a contact surface. The contact surfaces have longitudinal orientation and are placed sequentially along the longitudinal direction of the cable end section. The subbranch current terminals are separately insulated from the thermal insulating cover by means of separate electric insulators.

EFFECT: one ensures reliable and economically efficient connection between phase conductors and neutral conductors in these cables with external equipment.
