Embodiment
Halogen material is mostly adopted for the cable insulation used in prior art and restrictive coating, not only a large amount of dense smoke can be produced when breaking out of fire, and the very strong hydrogen halide of corrosivity can be produced, and the problem of fire-resistant insufficient strength, the utility model provides a kind of nanometer smoke-inhibiting flame retardant fire-resisting cable, the major design point of this utility model is: insulating barrier and restrictive coating are made up of polyvinyl chloride, polyethylene or ethylene-propylene rubber, its cable made very environmental protection; Conductor is surrounded with the flame retardant coating be made up of synthetic mica tape, fire resistance is excellent; One deck environment-friendly smoke-suppressing flame retardant coating is had outside cable cover(ing), it is remarkable that this cable presses down cigarette effect, flame retardant effect is desirable, not only reach smoke-inhibiting flame retardant object and environmental protection, smoke-inhibiting flame retardant coating can suppress the generation of cable smog, poison gas in a fire, and reduce the flammable performance of cable, improve visibility and the fail safe of scene of fire, be conducive to the escape unharmed of personnel.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be understood that, specific embodiment described herein only for explaining the utility model, and is not used in restriction the utility model.
As shown in Figure 1-2, cable of the present utility model comprises smoke-inhibiting flame retardant coating 3, is coated on the restrictive coating 2 in described smoke-inhibiting flame retardant coating 3 and is coated at least one cable inner core 1 in described restrictive coating 2, cable inner core 1 described in each comprises conductor 11 and the flame retardant coating 12 be coated on successively from inside to outside outside described conductor 11 and insulating barrier 13, and described flame retardant coating 12 is made up of synthetic mica tape.Wherein, cable inner core 1 is at least one, and namely cable inner core 1 can be one, two or more roots, specifically according to circuit need determine.
Particularly, Fig. 1 is the cross section structure schematic diagram of the nanometer smoke-inhibiting flame retardant fire-resisting cable of the utility model first embodiment.In the present embodiment, cable comprises a cable inner core 1, restrictive coating 2 and smoke-inhibiting flame retardant coating 3, and cable inner core 1 comprises conductor 11, flame retardant coating 12 and insulating barrier 13.Wherein, flame retardant coating 12 is coated on outside conductor 11, and insulating barrier 13 is coated on outside flame retardant coating 12, and restrictive coating 2 is coated on outside insulating barrier 13, and smoke-inhibiting flame retardant coating 3 to be coated on restrictive coating 2 outer and belong to outermost layer.Conductor 11, flame retardant coating 12, insulating barrier 13, restrictive coating 2 and smoke-inhibiting flame retardant coating 3 are coated successively from inside to outside, and gapless each other, gapless can ensure the intensity of whole cable, thus ensures the electric property of cable.
Fig. 2 is the cross section structure schematic diagram of the nanometer smoke-inhibiting flame retardant fire-resisting cable of the utility model second embodiment.In the present embodiment, be with the difference of the first embodiment, cable inner core 1 is three, the size of these three cable inner cores 1 is equal and be circle, three cable inner cores 1 twist together according to the lay preset and direction and form cross section is leg-of-mutton structure, be appreciated that cable inner core 1 also can be arranged in other shapes such as square, trapezoidal.Each cable inner core 1 comprises conductor 11 and the flame retardant coating 12 be coated on successively from inside to outside outside described conductor 11 and insulating barrier 13.Particularly, in three cable inner cores 1 in Fig. 2, the line of centres of each root cable inner core 1 is an equilateral triangle, tangent to ensure each two adjacent cable inner core 1.
Be understandable that, when cable inner core 1 is many, shape, the size of this multi-cable inner core 1 can be identical, also can be different, as cable inner core 1 can be circle, pancake or square etc.
Further, when cable inner core 1 is many, the gap between each adjacent described cable inner core 1 and described in each between cable inner core 1 and described restrictive coating 2 all has packed layer 4.Namely when cable inner core 1 is many, when this multi-cable inner core 1 arranges in restrictive coating 2, between cable inner core 1 or between restrictive coating 2 and cable inner core 1, space is had.The glass fiber material including high flame retardant is filled in these gaps, forms packed layer 4.Packed layer 4 adopts the wrapped formation of high flame retardant glass fiber material, can prevent flame from internally permeating, and protection cable inner core 2 is from destruction.In other embodiments, packed layer 4, except including high flame retardant glass fiber material, also includes semiconductive water-proofing powder, stops water to vertically move to electric wire, then both made electric wire breakage also can continue conduction in a humidity environment, and strengthened waterproof effect.
Further, when cable inner core 1 is many, the stranded direction of many described cable inner cores 1 by outer layers towards inner layers be followed successively by " S "-" Z "-" S " to.Respectively to direction of lay be prior art, be not described in detail at this.Adopt this kind of stranded multi-cable inner core 1 of stranded mode, multi-cable inner core 1 can be made to keep an entirety, not easily loose, there is good pliability simultaneously, make whole cable have extremely strong bend resistance ability, thus guarantee that the physical property of whole cable and electric property do not come and go by 1,000,000 times the impact bending motion.
Particularly, when cable inner core 1 is many, the quantity of its cable inner core 1 is 2-61 root, and namely the quantity of cable inner core mostly is 61 most, and reason considers practice and production capacity.Under the condition that cable inner core 1 quantity is different, the voltage withstand class of cable is also different, and general voltage withstand class comprises: 300/300V; 300/500V; 450/750V; 600/1000V.Concrete selection how many cable inner cores 1 voltage withstand class is according to actual needs determined.
In the utility model, described synthetic mica tape comprises SiO by mass fraction
