Abstract
The invention discloses a polyvinyl chloride insulation polyvinyl chloride jacket multi-layer fire-resistant multi-core cable. The polyvinyl chloride insulation polyvinyl chloride jacket multi-layer fire-resistant multi-core cable comprises a cable core which is formed by stranding a plurality of thread cores, the gap inside the cable core is filled with a filling core, a glass fiber band wraps the cable core, a third fire-resistant layer is arranged outside the glass fiber band in an extruding mode, a metal armor layer is arranged outside the third fire-resistant layer in a weaving mode, a polyvinyl chloride outer jacket is arranged at the outermost layer of the cable core in an extruding mode, and each thread core is composed of a conductor, a polyvinyl chloride insulation layer arranged outside the conductor in an extruding mode, a first fire-resistant layer arranged outside the insulation layer in a lapping mode, a shielding layer arranged outside the first fire-resistant layer in an extruding mode, and a second fire-resistant layer arranged outside the shielding layer in a lapping mode. The polyvinyl chloride insulation polyvinyl chloride jacket multi-layer fire-resistant multi-core cable has the advantages of being high in fire resistance, good in flame retardant effect, high in insulation reliability, long in service life and the like.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of polyvinyl chloride-insulated polyvinyl chloride multiple layer refractory multicore cable.
Background technology
Along with social development, the progress of science and technology, numerous power plant, smelter, oil play are to large-scale grouping of the world economy future development, skyscraper, public entertainment place, subway and underground street etc. continue to bring out, and its power consumption grows with each passing day, and the kind of electric wire and consumption be corresponding increase also.But electric wire is transmission & distribution electric energy, transmission of information both, be again " blasting fuse " of fire hazardous, yet common cable is in a single day burned when actual breaking out of fire, just can't switch on.But during many important events contingency breaking out of fires, the illumination of evacuating personnel, passage, fire protection alarm device, automatic fire-fighting facility and other emergency set all require cable can keep normal power-up at the appointed time when fire occurs.Therefore, people work out fireproof cable.
The fire resistance of simultaneously current cable is poor, in case breaking out of fire, cable fire can produce a large amount of dense smoke, makes a large amount of rescue works be difficult to carry out, the hydracid corrosive gas discharged during the substance combustion of Halogen, except harmful to human, also can cause certain infringement to equipment.
Summary of the invention
It is strong that the technical problem to be solved in the present invention is to provide a kind of fire resistance, good flame retardation effect, and insulating reliability is large, the polyvinyl chloride-insulated polyvinyl chloride multiple layer refractory multicore cable of long service life.
A kind of polyvinyl chloride-insulated polyvinyl chloride multiple layer refractory multicore cable of the present invention, comprise cable core, and described cable core is to form by the several wire core is stranded; Core is filled out in gap in cable core, and cable core outer cladding glass fibre belt extrudes the 3rd flame retardant coating outside glass fibre belt, braided metal armour outside the 3rd flame retardant coating, and the cable core outermost layer extrudes the polyvinyl chloride oversheath; Described core be by conductor and be extruded in the outer polyvinyl chloride insulation layer of conductor, wrapped outside insulating barrier the first flame retardant coating, be extruded in the screen outside the first flame retardant coating, wrapped the second flame retardant coating outside screen forms.
Further improve, described conductor is by many copper wires or aluminium wire is stranded forms.
Further improve, described the first flame retardant coating adopts the mica tape fireproof construction; Described the second flame retardant coating, the 3rd flame retardant coating adopt ceramic silicon rubber fireproof construction.
Beneficial effect of the present invention is:
Compared with prior art, the present invention adopts three layers of fire-resistant layer structure, has greatly improved the fire-resistant effect of cable, prevents that effectively cable from coming harmful to human and equipment at the breaking out of fire after-combustion a large amount of dense smoke of generation and poisonous corrosive gas.Insulating barrier, oversheath adopt pvc material, make the good flame retardation effect of cable, and then have extended the useful life of cable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment:
As shown in Figure 1, a kind of polyvinyl chloride-insulated polyvinyl chloride multiple layer refractory multicore cable of the present invention, comprise cable core, and described cable core is to form by the several wire core is stranded; Core 6 is filled out in gap in cable core, and cable core outer cladding glass fibre belt 7 extrudes the 3rd flame retardant coating 8 outside glass fibre belt 7, and at the outer braided metal armour 9 of the 3rd flame retardant coating 8, the cable core outermost layer extrudes polyvinyl chloride oversheath 10; Described core be by conductor 1 and be extruded in the outer polyvinyl chloride insulation layer 2 of conductor 1, wrapped outside insulating barrier 2 the first flame retardant coating 3, be extruded in the screen 4 outside the first flame retardant coating 3, wrapped the second flame retardant coating 5 outside screen 4 forms.Described conductor 1 is by many copper wires or aluminium wire is stranded forms, and described the first flame retardant coating 3 adopts the mica tape fireproof constructions, and described the second flame retardant coating 5, the 3rd flame retardant coating 8 adopt ceramic silicon rubber fireproof constructions.
The invention provides a kind of polyvinyl chloride-insulated polyvinyl chloride multiple layer refractory multi-core cable structure form and implementation method; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
