1. A cable support arrangement for a wind turbine comprising:
a plurality of self-clamping cable guards for clamping power cables of a power cable bundle of the cable support arrangement in the wind turbine, each self clamping guard comprising:
three recesses arranged about a central longitudinal axis of the self-clamping cable guard for positively clamping a power cable of the power cable bundle inside of each of the three recesses, and
three wear protection plates arranged about the central longitudinal axis, whereby each of the three recesses comprises an open side for insertion of a respective power cable of the power cable bundle therein, each of the open sides of one of the three recesses being respectively limited by two of the three wear protection plates to protect the power cables clamped inside the recesses from wear; and
at least one cable bundle guide and multiple power cable bundles, each power cable bundle consisting of three power cables, and whereby each of the multiple self-clamping cable guards clamps in every one of the three recesses one of the three power cables of each of the multiple power cable bundles, and whereby each one of the multiple plurality of self-clamping cable guards with the power cables clamped inside thereof is arranged in one of multiple through-openings inside of the at least one cable bundle guide;
wherein the at least one cable bundle guide comprises a tilting mechanism for tilting the cable bundle guide around a tilting axis perpendicular to the central longitudinal axis of the plurality of self-clamping cable guards.
