Description

Referring here to Figure 3, another exemplary cable 30 according to an embodiment of the disclosure is shown. The cable 30 comprises two layers of flame-retardant tapes 32, 34 (e.g., mica tape, ceramic tape ( Al₂O₃ and SiO₃ ), silica tape ( SiO₃ ), or mesh braid (equipped with Al₂O₃ and SiO₃ ), etc.) sandwiching a steel tape 36 (e.g., A606 alloy). The cable 30 further comprises a flame-retardant jacket material 38 (e.g., flame-retardant plastic elastomer) configured to surround the outer flame-retardant tapes 32. Similar to the configuration in Figure 2, the combination of flame-retardant tapes 32 and 34, steel tape 36 and flame-retardant jacket 38 functions to protect the copper conductors 40, 42 from degradation and oxidation. The central conductor 40 is held in place by a dielectric 44 that spirally surrounds the conductor 40, which may comprise, for example, a ceramic rope. However, it should be understood that other forms of ceramics may be used.
