Abstract
A fire-resistant safety cable may include at least two electrical conductors, an insulating layer around each of the at least two electrical conductors in order to obtain at least two insulated elements, and an outer jacket surrounding the at least two insulated elements. The cable may have, in cross-section, an external outline including at least two substantially plane faces that are substantially parallel to each other. The insulating layer may be formed from at least one polymeric material being adapted to be converted, at least on a surface of the at least one polymeric material, into a ceramic state at high temperatures in a fire. The at least two insulated elements may be mutually adjacent, side by side, with axes of the at least two insulated elements lying in a plane between the at least two substantially plane faces.
