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 separate insulated elements; and/or an outer jacket surrounding the at least two separate insulated elements. The insulating layer may be formed from at least one polymeric material capable of being converted, at least on a surface of the insulating layer, into a ceramic state at high temperatures in a fire. The at least two separate insulated elements may be untwisted and arranged so as to be parallel to each other, side by side, and separated by a space. The outer jacket may at least partially fill the space. A thickness of the outer jacket may be approximately constant over an external surface of the at least two separate insulated elements.
