Abstract
A wind turbine blade is disclosed. The blade includes a heating mat for generating heat. The heating mat is mounted at an outer surface of the blade. The heating mat includes a first section with a first end section and a second section with a second end section. The first end section and the second end section are electrically connectable to a respective power terminal for supplying power to the heating mat. The second end section defines an opposite end section of the heating mat in a longitudinal direction of the heating mat with respect to the first end section. The first section and the second section run along the surface of the blade in one or more loops from the first end section to the second end section.

A blade for a wind turbine, the blade comprising:
- a heating mat for generating heat is mounted at an outer surface of the blade, the heating mat comprising a first section with a first end section and a second section with a second end section, the first end section and the second end section are electrically connectable to a respective power terminal for supplying power to the heating mat,
- wherein the second end section defines an opposite end section of the heating mat in a longitudinal direction of the heating mat with respect to the first end section, and
- wherein the first section and the second section run along the surface of the blade in at least one loop from the first end section to the second end section;
- wherein the first section and the second section are arranged such that the first section and the second section at least partially overlap each other and an insulation layer is interposed between the first section and the second section.
A method of manufacturing a blade with a heating system for a wind turbine, the method comprising:
- mounting a heating mat for generating heat at an outer surface of the blade of the wind turbine, wherein the heating mat comprises a first section with a first end section and a second section with a second end section, the second end section defines an opposite end section of the heating mat in a longitudinal direction of the heating mat with respect to the first end section;
- and
- electrically connecting the first end section and the second end section to a respective power terminal,
- wherein the first section and the second section run along the surface of the blade in one or more loops from the first end section to the second end section,
- wherein the first section and the second section are arranged such that the first section and the second section at least partially overlap each other and an insulation layer is interposed between the first section and the second section.
