Abstract: A graft coated pre-insulated pipe with fire retardant properties including a graft coating applied to the exterior of a pre-insulated pipe. The graft coating includes a graft solution and an expandable insulation material. The invention prevents damage to pre-insulated pipes caused by the expansion of the gasses in the cells of the foam within the pre-insulated pipe as a result of exposure to heat.

Abstract: The invention relates to a method of lightning-proofing a blade (1) on a wind-energy plant, which blade comprises a blade shell (2) configured essentially as a fibre-reinforced laminate, which laminate comprises electrically conductive fibres, wherein the blade comprises at least one lightning arrester (9) configured for conducting lightning current, including preferably to ground. The method comprises that the electrically conductive fibres are connected to each other, and that at least one metallic receptor (4, 24, 25) is arranged for capturing lightning current at or in proximity of the external face of the blade; and that the receptor and the fibres are connected to the lightning arrester for equalising the difference in potential between the lightning arrester and the electrically conductive fibres. When the electrically conductive fibres are connected to each other, the fibres will cooperate on the conduction of a possible lightning current to prevent the current from running in individual fibres. Simultaneously the metallic receptor will serve as the primary lightning capturing device and reduce the risk of lightning striking the laminate. The receptor being connected to the lightning arrester, the current will predominately be conducted to ground, while the risk of transfer to the laminate is minimised in that a possible difference in potential between fibres and lightning arrester has been equalised.
