1. The most termite-proof low-smoke halogen-free inflaming-retarding cable, it is characterised in that include the cable core being made up of some heart yearns and be coated on describedThe polyester belt lapping layer that cable core is peripheral, each heart yearn includes conductor and is coated on the insulating barrier that described conductor is peripheral, at described cableIt is provided with packed layer between core and described polyester belt lapping layer, the periphery of described polyester belt lapping layer is provided with restrictive coating, instituteStating insulating barrier is 90 DEG C of low-smoke zero-halogen flame-retardant termite-proof insulating barriers, including following weight ratio:

  • 70~

    90 parts of regenerative low-smoke halogen-free electricityCable material particle, 12~

    25 parts of PVC, 10~

    20 parts of insulating packings, 3~

    5 parts of modifying agent, 2~

    5 parts of compatilizers, 0.3~

    0.6 part resistsOxygen agent, 1~

    1.5 part of lubricant, 2~

    3 parts of black masterbatch, 2~

    3 parts of termite-proof masterbatch;

    Described insulating barrier is the most first to insulationLayer material carries out the pre-heat treatment, and preheating temperature is 70~

    80 DEG C, and preheating time is 3~

    5 hours, and extruder has four warm sections,These four warm sections are followed successively by 140~

    165 DEG C, 140~

    160 DEG C, 110~
