High-reliability multifunctional cable

Abstract

A high-reliability multifunctional cable comprises a power transmission unit, a coaxial radio frequency signal composite unit, an optical fiber control composite unit, a heat-insulation fireproof filling type inner sheath, a water-blocking flame-retardant impact-resistant buffer layer, a rat-proof, termite-proof and impact-resistant reinforcing layer and an impact-resistant flame-retardant fireproof outer sheath. The high-reliability multifunctional cable is characterized in that: the power transmission unit is composed of a water-blocking fire-resistant insulation wire core and a reinforcing protection layer; the coaxial radio frequency signal composite unit is composed of a coaxial radio frequency unit wire core, a copper wire braided copper strip shielding layer, a signal transmission unit water-blocking fire-resistant insulation wire core, a water-blocking layer, a reinforcing protection layer and a heat-insulation flame-retardant protection layer; and the optical fiber control composite unit is composed of a stainless steel tube optical unit, a water-blocking fire-resistant control insulation wire core, a braided shielding water-blocking layer, a reinforcing protection layer and a heat-insulation flame-retardant protection layer. The high-reliability multifunctional cable has the advantages of being excellent in impact resistance, fire resistance, explosion resistance, water resistance and rat and ant resistance, protecting life and material safety when disasters occur, avoiding repeated wiring and reducing cost.
