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).
Claims16
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 comprises at least one multifilament thread made of glass having between 1000 and 6000 hair-fine filaments which is wound around the conductor and whose windings are contiguous so as to create a completely closed sleeve for the conductor, and
- said line includes a protective layer of a halogen-free, temperature-resistant insulation material encasing the sleeve, wherein the protective layer is made of crosslinked, ceramized silicone.
