Abstract:
(EN) Improved Electro-Thermal Heating Elements The present invention relates to an Electro-Thermal Heating element for a wind turbine blade comprising an electrically conductive resistive material; two active busbars for supplying electrical power to the electrically conductive resistive material; and at least one dummy busbar at a predetermined spacing between the two active busbars on the electrically conductive resistive material. The present invention is also directed to a method of repair of the Electro-Thermal Heating Element.
(FR) Des éléments de chauffage électrothermiques améliorés de la présente invention concernent un élément de chauffage électrothermique pour une pale d'éolienne comprenant un matériau résistif électroconducteur; deux barres omnibus actives pour fournir de l'énergie électrique au matériau résistif électroconducteur; et au moins une barre omnibus factice au niveau d'un espacement prédéterminé entre les deux barres omnibus actives sur le matériau résistif électroconducteur. La présente invention concerne aussi un procédé de réparation des éléments de chauffage électrothermique.
