Its structure is mainly composed of cable core, longitudinal covering a layer of two-sided synthetic mica tape outside cable core, inner sheath packed with ceramic sheathing materials, steel wire armor outside inner sheath, wrapping a layer of two-sided synthetic mica tape outside. Its structure is mainly composed of cable core, longitudinal covering a layer of two-sided synthetic mica tape outside cable core, inner sheath packed with ceramic sheathing materials, steel wire armor outside inner sheath, wrapping a layer of two-sided synthetic mica tape outside. In this paper, a kind of flame retardant and fire-resistant optical cable is prepared with ceramic sheathing materials. The multi-layered sheath includes. The invention belongs to the technical field of optical cables, and particularly relates to a flame-retardant optical cable which comprises a rubber sleeve, an elastic rubber column, an inner sleeve, a fireproof mud layer, an aluminum foil belt, an outer sleeve, an elastic steel pipe, a connecting. Flame-retardant optical cables are an essential component in the telecommunications industry, ensuring the safe and efficient transmission of data. These cables are designed to resist combustion and minimize the spread of fire, making them ideal for use in buildings where fire safety is a priority. In addition, also with water spray and. Our fire resistant/fire survival cables feature a steel wire/steel wire braiding/corrugated steel tape armour to provide mechanical strength. The outer sheath is made from black UV-stabilised and.
