Abstract
The invention relates to an electrical line (L) having at least one electrical conductor ( ) enclosed by temperature-resistant insulation ( ) which ensures the functionality of the line ( ) in case of fire. To minimize the fire load of the line ( ), the insulation ( ) comprises at least one multifilament thread ( ) made of glass which is wound around the conductor ( ) and whose windings are contiguous so as to create a completely closed sleeve ( ) for the conductor ( ). A thin protective layer ( ) of a halogen-free, temperature-resistant insulation material is applied all over the sleeve ( ).
