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. 改进的电热加热元件本发明涉及用于风力涡轮机叶片的电热加热元件，其包括导电电阻材料；用于向导电电阻材料供应电力的两个活动汇流条；和至少一个虚设汇流条，其在导电电阻材料上以预定间隔位于两个活动汇流条之间。本发明还涉及维修电热加热元件的方法。
