Stranded carbon fiber cable core is 4, and evenly distributed is in the interference shielding layer is drawn to the aluminium foil wheat, and stranded carbon fiber cable core and aluminium foil wheat are drawn to disturb has the filler between the shielding layer, and the filler can be made by asbestos. The armor is woven by the steel wire and is formed, and the steel wire surface scribbles fire -resistant high temperature resistant coating, and steel wire braiding density is 60%-70%. The utility model has the advantages of, simple process, simple structure, convenient production, extension cable life, the security that also increases operational environment.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of shielded type cable.
Background technology
Shielded type cable application is comparatively extensive, and the shield effectiveness of shielded type cable is general all fine, but common shielded type cable is high temperature resistant and anti-aging, mechanical strength aspect, and effect is not fine.The heat-resisting quantity of shielded type cable and resistance to compression, anti-corrosion effects have much room for improvement.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides one can solve existing shielded cable mechanical strength not high, the shielded type cable that heat-resisting quantity is not strong.
The purpose of this utility model is achieved through the following technical solutions: a kind of shielded type cable; comprise conductor; conductor periphery is surrounded with PVC insulating barrier; conductor and PVC insulating barrier constitute carbon fiber cable core; be surrounded with aluminium foil wheat outside multi-strand carbon fiber cable core and draw interference shielding layer, aluminium foil wheat is drawn outside interference shielding layer and is surrounded with mica lapping layer, is provided with silica gel high-temperature-resistant layer outside mica lapping layer; be provided with armour outside silica gel high-temperature-resistant layer, outside armour, be provided with protective sleeve.
Further improvement of the utility model is: described multi-strand carbon fiber cable core is 4, is evenly distributed on aluminium foil wheat and draws in interference shielding layer.
Further improvement of the utility model is: described multi-strand carbon fiber cable core and aluminium foil wheat are drawn between interference shielding layer filler, and described filler can be made up of asbestos.
Further improvement of the utility model is: described armour is formed by braided steel wire, and Steel Wire Surface scribbles fireproof high-temperature resistant coating, and braided steel wire density is 60% ~ 70%.
The utility model compared with prior art has the following advantages:
Multi-strand carbon fiber cable core is 4, being evenly distributed on aluminium foil wheat draws in interference shielding layer, multi-strand carbon fiber cable core and aluminium foil wheat are drawn between interference shielding layer and are filled with insulating material, and filler can play the effect of firm cable core, make cable profile comparatively rounding; Filler can select asbestos to make, and has the effect of high-tensile, high flexible, chemically-resistant and thermal etching; Aluminium foil wheat draws interference shielding layer to be generally used for outside Stranded cable core, and cost is low, easy to make; The fire resistance of mica is best, can extend the useful life of cable; Silica gel high-temperature-resistant layer, high temperature resistant, anticorrosion, ageing resistance, elasticity and flexibility well, can play the effect extending carbon fiber cable useful life equally; Armour serves flexible, not frangibility, enhances two to lead the crushing resistance of carbon fiber cable, the effect of mechanical strength; Protective sleeve outside armour, waterproof, strengthens the effect of shielding, extends the useful life of armour simultaneously.
accompanying drawing illustrates:
Fig. 1 is the structural representation of execution mode one of the present utility model;
Number in the figure: 1-conductor, 2-PVC insulating barrier, 3-carbon fiber cable core, 4-aluminium foil wheat draw interference shielding layer, 5-mica lapping layer, 6-silica gel high-temperature-resistant layer, 7-armour, 8-protective sleeve, 9-filler.
