Abstract
The invention relates to an electrical line (L) having at least one electrical conductor (1) enclosed by temperature-resistant insulation (2) which ensures the functionality of the line (1) in case of fire. To minimize the fire load of the line (1), the insulation (2) comprises at least one multifilament thread (3) made of glass which is wound around the conductor (1) and whose windings are contiguous so as to create a completely closed sleeve (4) for the conductor (1). A thin protective layer (5) of a halogen-free, temperature-resistant insulation material is applied all over the sleeve (4).

An electrical line having at least one electrical conductor enclosed by temperature-resistant insulation which ensures the functionality of the line in case of fire, characterized in that
- the insulation (2) comprises at least one multifilament thread (3) made of glass which is wound around the conductor (1) and whose windings are contiguous so as to create a completely closed sleeve (4) for the conductor (1), and
- said line includes a thin protective layer (5) of a halogen-free, temperature-resistant insulation material encasing the sleeve (4).
