[0002] Ordinary wires and cables are prone to insulation aging and scorching at high temperatures, making the related performance of the cables damaged and unable to be used. High-temperature wires and cables can work normally and stably at high temperatures, and the signal or power transmission performance is not affected. The cable has a long service life, but most of the existing high temperature resistant cables use metal to achieve the effect of flame retardancy, but the melting point of metal is lower than that of ceramics, so it should be improved

The present invention relates to the field of cables, in particular to a high temperature resistant cable, including cable cores, the cable cores are aluminum alloy conductors, each aluminum alloy conductor is externally extruded with a cross-linked polyethylene insulation layer, each aluminum alloy conductor and each cross-linked polyethylene insulation layer form a cable group, three cable groups are provided, isolation stretching group is arranged between the three groups of cable groups, the isolation stretching group comprises a tension-resistant core located at the center of three groupsof cables, a rubber part arranged on the outside of the tension core, a spacer provided on the exterior of the rubber member and enclosing the three sets of cable groups, the isolation frame is wrapped with a mica wrapping tape, The outer part of the mica wrapping tape is provided with a metal shielding layer, the outer part of the metal shielding layer is extruded with a silicone rubber outer sheath, and the cable group is wrapped by a spacer made of soft ceramics inside the invention, so that the inner cable core can be hardened and protected from damage under the high temperature condition, thus gaining time for rescue by people.
Description
Technical field [0001] The invention relates to the field of cables, in particular to a high temperature resistant cable. Background technique [0002] Ordinary wires and cables are prone to insulation aging and scorching at high temperatures, which will damage the related performance of the cables and cannot be used. High-temperature wires and cables can work normally and steadily at high temperatures, and the signal or power transmission performance will not be affected, and it can be guaranteed The cable has a long service life, but most of the existing high temperature resistant cables use metal to achieve flame retardant effect, but the melting point of metal is lower than that of ceramics, so it should be improved. Summary of the invention [0003] In order to solve the above problems, the present invention proposes a high temperature resistant cable. [0004] A high-temperature resistant cable, comprising a cable core, the cable core is an aluminum alloy conductor, the outsi...
