The present invention also relates to a wind turbine tow- er and a wind turbine comprising such cable protection system. Prior art The green transition has increased the focus on renewable energy pro- duced by using wind turbines, because wind turbines can create relia- ble, cost-effective, pollution-free energy. A reliable electrical connection from a generator to an external grid is essential for modern wind tur- bines.
Due to the large height of the wind turbine towers, an electrical cable hanging from the top end of a tower to the bottom end of the tower is exposed to large tensile forces induced by the weight of the cable itself. Accordingly, it is desirable to have an efficient and robust way of pro- tecting electrical cables inside a wind turbine tower.
It is an object of the present invention to provide a cable protection system for a wind turbine tower.
Summary of the invention The object of the present invention can be achieved by a cable protec- tion system for a wind turbine tower as defined in claim 1.

DK 2020 01410 A1 11 48 and a second wire 48’ extending parallel to the first wire 48. Each cable 50, 50', 50”, 507” is attached to a clamping member 54, 54’, 54”,
54.
A first clamping structure 52 is fixed to the first wire 48, wherein a sec- ond clamping structure 52’ is fixed to the second wire 48’. The clamping structures 52, 52' are attached to a mounting structure 62. In one em- bodiment, the mounting structure 62 is plate-formed.
The mounting structure 62 is attached to clamping members 54, 54', 54”, 54””, Therefore, the load of the cables 50, 50', 50”, 50" (intro- duced by gravity) is transferred to the wires 48, 48’ through the clamp- ing members 54, 54’, 54”, 54”” via the mounting structure 62 to the clamping structures 52, 52’. The strain-relieving member 60 is provided to prevent each cable 50, 50', 50”, 50'” from being exposed to large tensile forces induced by the weight of the cable itself.
The wires 48, 48' may be steel wires 48, 48’. The cables 50, 50', 50”, 50”” may be semi-conductor or multi-conductor cables. A service lift 64 is provided next to the strain-relieving member 60. The service lift 64 is suspended in wires (not shown) allowing the service lift 64 to be verti- cally displaced. The service lift 64 comprises an opening or a door and is arranged adjacent to the cables 50, 50', 50”, 50'” so that the cables 50, 50’, 50”, 507” can be accessed through the opening or door and hereby serviced by a person inside the service lift 64.

A work platform and boat landing area 26 is attached to the transition piece 14. The work platform and boat landing area 26 extends from the central area of the transition piece 14 and protrudes laterally from the remaining part of the jacket support structure 28. The work platform and boat landing area 26 is attached to the transition piece 14 by means of connection structures 36. The connection structures 36 may be shaped as tubular structures or bars by way of example. A person 34’ is standing on the work platform and boat landing area 26. A railing 42 prevents the person 34’ from falling over.
An additional platform 65 is attached to one of the legs of the jacket support structure 28. A person 34” stands on this platform 65 and is protected from falling over by a railing 42. The platform 65 is connected to the work platform and boat landing area 26 through a ladder extend- ing between the platform 65 and the work platform and boat landing area 26. In one embodiment, a separate platform 65 s provided for each joint between adjacent leg segments. Hereby, it is possible to ser- vice the joints.
A centrally arranged entrance 30 is provided at the transition piece 14.
A person 34 has entered the inner space in the transition piece 14 through the entrance 30.
DK 2020 01410 A1 13 Two parallel tacks 46, 46’ are provided at the work platform and boat landing area 26. The tracks 46, 46’ extend through an area provided straight below the entrance 30. Accordingly, it is possible to slide ob- jects along the tracks 46, 46’ into a position, from which the objects are placed below the entrance 30. From this position the objects can be lift- ed up through the entrance 30 and hereby enter the interior portion of the transition piece 14. Several cables 50, 50’, 50”, 50”” are hanging from a first high position (near the top of the tower 6) inside the tower 6 to a lower position near the bottom portion of the tower 6. The cables 50, 50’, 50”, 50”” are very heavy due to their large length. Accordingly, a cable protection system 70 comprising strain-relieving members 60 as the one shown and explained with reference to Fig. 5A and Fig. 5B is used to protect the cables 50, 50', 50”, 50". The cable protection system 70 comprises a first strain-relieving member 60 and a second strain-relieving member 60 that are attached to two parallel wires 48, 48’ hanging from a mounting structure attached to the top portion of the tower 6.
A service lift 64 is provided next to the uppermost strain-relieving member 60. The service lift 64 is moveably mounted to be vertically displaced. The service lift 64 is provided with an opening and is ar- ranged adjacent to the cables 50, 50’, 50”, 50". Hereby the cables 50, 50’, 50”, 50'” can be accessed through the opening or door and hereby serviced by a person inside the service lift 64.
Inside the inner space of the transition piece 14, there is access to a ladder 58 extending along the cables 50, 50’, 50”, 50".
