  • Publication number: 20180094621
    Abstract: A receptor assembly (1; 5) for a lightning protection system for a wind turbine blade (2) is disclosed, comprising electrically conducting current carriers (6; 19) and mounting bolts (9) and/or threaded rods (20), wherein each of the current carriers is a metallic part arranged and dimensioned to surround at least a part of a mounting bolt or a threaded rod without being in electrical contact with the mounting bolt or threaded rod, at least a part of the external surface at one end of each current carrier is arranged to be a contact surface (10) for mechanical and electrical contact to a receptor base (3; 16) in such a way that, in the case of a lightning impact on the receptor, the lightning current passes through the one or more current carriers rather than through the one or more mounting bolts and/or threaded rods on its way through the receptor.

  • Publication number: 20170321661
    Abstract: A fully insulated tip unit (1) for a lightning protection system for a wind turbine blade (2) is disclosed, comprising an electrically conducting tip (3), which tip consists of an external part (4) and an internal part (5), at least one side receptor base (6), an internal tip unit conductor (8), an insulated electric cable (9) for forming the outermost part of a down conductor (10), and a connection element (12) for establishing electrical connection between the insulated electric cable and the other conducting parts of the tip unit, wherein the internal part of the tip, the side receptor base(s), the internal tip conductor, the connection element and one end of the insulated electric cable are all embedded by casting in an insulating material (13) leaving only the external part of the tip and the other end of the insulated electric cable uncovered by the insulating material. Furthermore, a wind turbine blade comprising such a tip unit is disclosed.
