1. A power cable accessory assembly comprising:
a first power cable including:
first conductor, and
a first electrical insulation layer arranged around the first conductor,
wherein the first electrical insulation layer includes a first insulation groove extending circumferentially along an outer surface of the first electrical insulation layer;
a connection sleeve including:
a first axial end opening receiving an end portion of the first conductor protruding axially from the first electrical insulation layer, and
a first locking sleeve groove extending circumferentially along an outer surface of the connection sleeve; and
a first locking sleeve including:
a first radially inwards extending flange engaging with the first insulation groove and a second radially inwards extending flange engaging with the first locking sleeve groove to restrict axial movement between the first electrical insulation layer and the connection sleeve,
wherein the first radially inwards extending flange has a first radial dimension that decreases gradually in an axial direction towards the connection sleeve, and wherein the first insulation groove has a second radial dimension that decreases gradually in the axial direction towards the connection sleeve;
wherein the first radially inwards extending flange has a surface defines the gradually decreasing first radial dimension, wherein in a longitudinal section of the first locking sleeve the surface defines an axis that intersects a longitudinal axis of the first locking sleeve with an angle in a range of 15-80 degrees.
