Disclosed a wind turbine blade comprising a main laminate and a method for manufacturing a main laminate for a wind turbine blade. The wind turbine blade extends in a longitudinal direction from a root to a tip and comprising a pressure side, a suction side and a chord line extending between a leading edge and a trailing edge. Particularly, lightning protection of such main laminate is disclosed.

Lightning protection system for a main laminate

Disclosed is a wind turbine blade comprising a first blade section extending along a longitudinal axis from a root end to a first end and a second blade section extending along the longitudinal axis from a second end to a tip end. The wind turbine blade comprising a spar beam configured for connecting the first blade section and the second blade section. The first blade section comprises a first down conductor and the second blade section comprises a second down conductor. The wind turbine blade comprises a conductive connector element for electrically connecting the first down conductor and the second down conductor.

Lightning protection of a section wind turbine blade

Disclosed is a wind turbine blade comprising a first blade section and a second blade section connected to the first blade section. The wind turbine blade comprises a first down conductor for conducting lightning current to ground. The blade further comprises one or more lightning receptors at or in proximity of an external surface of the wind turbine blade. A smallest distance from a first lightning receptor of the one or more lightning receptors to an interface between the first blade section and the second blade section may be less than or equal to a chord length of a chord of the wind turbine blade at the interface between the first blade section and the second blade section.

Lightning protection for a wind turbine blade

Disclosed is a support element for a lightning protection system of a wind turbine blade comprising: a first surface configured to face towards the suction side or the pressure side of the wind turbine blade; a second surface opposite the first surface; a root side surface configured to face towards the root of the wind turbine blade; and a tip side surface configured to face towards the tip of the wind turbine blade; wherein the first surface comprises a first receptor base recess configured to receive a first receptor base for coupling with a first receptor of the lightning protection system.

Lightning receptor bracket

Disclosed is a spar beam and a wind turbine blade comprising a spar beam. The wind turbine blade comprising a first blade section extending along a longitudinal axis from a root to a first end and a second blade section extending along the longitudinal axis from a second end to a tip. The spar beam comprises a conductive beam sheath circumscribing at least a beam sheath angular distance of the spar beam about the spar beam axis and longitudinally extending from a fourth beam axis position to a fifth beam axis position.

Lightning protection of a sectioned wind turbine blade

Disclosed is wind turbine blade and a spar beam for structurally connecting a first blade section and a second blade section of a wind turbine blade. The spar beam comprises a first fibre reinforced element extending parallel to a spar beam axis. The spar beam comprising a conductive beam sheath circumscribing at least a beam sheath angular distance of the spar beam about the spar beam axis and longitudinally extending from a fourth beam axis position to a fifth beam axis position. The first fibre reinforced element is positioned between the conductive beam sheath and the spar beam axis.
