Abstract
Official abstract text for this publication.
There is provided a wind turbine rotor blade comprising a rotor blade casing, and a lightning protection system having at least one lightning protection cable and a lighting protection cable holder. The lighting protection cable holder is fixed in or to the inside of the rotor blade casing. The lighting protection conductor holder has a first part and a second part. The first part is fixed to an inside of the rotor blade casing and has a receiving portion for receiving the lighting protection cable. The second part is in the form of a cover or covering means and is placed over the receiving portion. The first and second parts each have a radar-absorbing core or a radar-absorbing layer and an electrically insulating material which surrounds the radar-absorbing core or the radar-absorbing layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wind turbine rotor blade, comprising: a rotor blade casing; and a lightning protection system having at least one lightning protection cable and a lighting protection cable holder, wherein the lighting protection cable holder has a first part and a second part, wherein the first part is coupled to an inside portion of the rotor blade casing and has a receiving portion for receiving a longitudinal length of the at least one lighting protection cable, wherein the second part forms a cover that is placed over the receiving portion and covers the longitudinal length of the at least one lighting protection cable, and wherein the first and second parts each have a radar-absorbing core or a radar-absorbing layer and an electrically insulating material surrounding the radar-absorbing core or the radar-absorbing layer. 2. The wind turbine rotor blade according to claim 1 wherein: the first part of the lighting protection cable holder has a straight adhesive portion, and a receiving portion, the receiving portion having radar-absorbing material and electrically insulating material surrounding the radar-absorbing material. 3. The wind turbine rotor blade according to claim 2 , wherein the straight adhesive portion is made of an electrically insulating material. 4. The wind turbine rotor blade according to claim 2 , wherein the receiving portion is of a U-shaped or C-shaped configuration and is configured to receive the lighting protection cable. 5. The wind turbine rotor blade according to claim 2 , wherein the second part is of a C-shaped or U-shaped configuration and is placed over the receiving portion. 6. The wind turbine rotor blade according to claim 2 wherein the radar-absorbing material represents a Salisbury screen or a Dallenbach layer. 7. The wind turbine rotor blade according to claim 1 wherein the electrically insulating material is a thermoplastic polyurethane (TPU). 8. A wind turbine, comprising: a hub; and the wind turbine rotor blade according to claim 1 coupled to the hub. 9. The wind turbine rotor blade according to claim 1 , wherein the receiving portion is configured to receive an entire longitudinal length of the at least one lighting protection cable. 10. The wind turbine rotor blade according to claim 9 , wherein the second part covers the entire longitudinal length of the at least one lighting protection cable. 11. The wind turbine rotor blade according to claim 1 , wherein the second part overlaps portions of the first part.
