An electrical cable (K) has at least two strands ( ) consisting of insulated conductors ( ) stranded together. Insulation on the strands ( ) consists of an inner layer in contact with the conductor, and which is softer than an outer layer. The strands ( ) are surrounded by an inner sheathing ( ). The cable (K) also has an electric shield ( ) and an outer sheathing ( ). A separator layer ( ) is between the strands ( ) and the inner sheathing ( ), consisting of an inner layer ( ) fixedly joined together with an outer layer ( ). The inner layer ( ) facing the strands ( ) is softer than the outer layer ( ), having an approximately circular peripheral surface and in firm contact with the separator layer ( ) or the strands ( ). The electric shield ( ) consists of at least one essentially closed tubular metallic layer and a stranded layer and/or braiding of metallic wires in contact with the metallic layer.

Electric cable for connection of mobile electric consumers

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 ( ).
