Abstract: A electric swivel, LVES, in a swivel stack, includes an annular outer element defining a cylindrical chamber around an axis S and an cylindrical inner element coaxial with the outer element. The cylindrical chamber is sealed at an upper side with an annular cover and is configured for rotation relative to the inner and outer element around the axis S. The inner element includes at an inner radial side first and second bearing parts defining an inner bearing. The outer element includes at an outer radial side first and second bearing parts defining an outer bearing. The inner bearing includes an inner annular interface between the first and second bearing parts, the outer bearing includes an outer annular interface between the first and second bearing parts. Each of the annular interfaces is coaxial with the inner and outer element, and each annular interface is configured as a flame conducting path.

Abstract: A high voltage connector includes an electric terminal and a housing elongated in a first direction along a longitudinal axis of the connector. An end surface of the electric terminal is mounted on an proximal end surface of the elongated housing with the respective body axis directions of the housing and the connector in parallel, and is arranged with an outer electric connection area for connection to an external electric terminal. The elongated housing is arranged at a distal end to receive at least one power cable for internal electrical connection of the at least one power cable with an inner connecting area of the electric terminal. The high voltage connector includes an encapsulating casing that encloses the electric terminal and the elongated housing in the first direction, and the encapsulating casing provides a closed space between the casing and the housing.
