Abstract
The utility model relates to a double-shielding instrument cable resistant to carbon hydrocarbon fire for ocean engineering. The periphery of a core wire conductor of the cable is wrapped with core wire mica tapes and is extruded with insulation layers, so that insulation core wires are formed. The insulation core wires are twisted pairwise to form twisted wire pairs, the periphery of each twisted wire pair is wrapped with an independent shielding layer, and the inner side of the independent shielding layer is provided with a drainage wire. Multiple groups of twisted wire pairs are retwisted to form a cable core, and the periphery of the cable core is filled with a filling core. The periphery of the filling core is wrapped with a whole shielding layer, and the inner side of the whole shielding layer is provided with a drainage wire. The periphery of the whole shielding layer is extruded with a halogen-free liner layer, and the periphery of the halogen-free liner layer is coated with an armored layer braided by tinned copper wires. The periphery of the armored layer is extruded with a flame-retardant crosslinked polyolefin inner sheath, and the periphery of the inner sheath is extruded with a polyolefin sheath resistant to carbon hydrocarbon fire. The periphery of the polyolefin sheath resistant to carbon hydrocarbon fire is wrapped with a cable wire mica tape, and the periphery of the cable wire mica tape is extruded with a flame-retardant non-crosslinked polyolefin outer sheath. The cable can prevent the external high temperature from quickly extending to the inner part of the cable during carbon hydrocarbon fire occurrence, and the purpose of resistance to carbon hydrocarbon fire of the cable is realized.
