Brief description of the drawings

Fig. 1 is the structure diagram of the utility model military information technological service three proofings islands and reefs private cable.

Embodiment

1 pair of the utility model further illustrates below in conjunction with the accompanying drawings.

A kind of military information technological service three proofings islands and reefs private cable, most the inside is conductor 1, and conductor 1 is by anti-oxidant micro- Alloy round copper wire+welding wire is reinforced is twisted；In the insulating layer 2 that 1 outer wrapping modified polyvinyl chloride material of conductor is made； Then 7 insulated wire cores being made of conductor 1 and insulating layer 2 aggregations are become into cable core, the wrapped polyester belt outside cable core, braiding screen Longitudinal wrap aluminium-plastic tape before covering；The outer anti-oxidant microalloy welding wire composition shielded layer 5 of braiding outside aluminium-plastic tape；Shielding Modified polyvinyl chloride protective layer 6 is extruded outside layer 5, and uses cross-linking radiation.

Conductor 1 is reinforced twisted by 5 class conductors against oxidation microalloy round copper wires+welding wire, conductor rounding after being twisted, single Silk cannot have connector.

Insulating layer 2 is produced using polychloroethylene insulation material, and insulation is closely wrapped outside conductor, and 6000V is crossed after insulation cooling Spark pressure-proof inspection.

Lapping layer 4 is one layer of polyester belt be overlapping wrapped and one layer of aluminium-plastic tape longitudinal wrap.

Shielded layer 5 is formed using the braiding of anti-oxidant microalloy welding wire, and coverage rate is not less than 85%, with aluminium-plastic tape Shielding is formed together, and shielding properties is very good.

Protective layer 6 uses cross-linking radiation using the production of modified polyvinyl chloride protective cover material squash type, is closely extruded in cable core Outside, rounding, without acceptance of persons, cable core crosses medical talc powder when extruding protective layer, is separated easy to sheath and cable core.

Reinforcer 3 is equipped between insulating layer 2 and lapping layer 4 so that cable can preferably bear the mechanical pressure in the external world, should Layer is additionally provided with polymer mix 7 except reinforcer, can preferably ensure the drying inside cable, lifts dampproof effect.

Rodent-proof material in protection against rodents layer 8 is capsaicine, can preferably prevent that mouse from biting cable.

The utility model product material therefor is environment-friendly materials, does not produce during production and use and have to environment Evil material.
