Embodiment
Below in conjunction with accompanying drawing 1, the utility model is described in more detail.
As shown in Figure 1, a kind of termite-proof heat-proof combustion-resistant electric power cable, it comprises insulation cable core group, described insulation cable core group outside is from being innerly outwards disposed with filler 7, band 3, extruding lining 4, steel belt layer 5 and termite-proof oversheath 6, described insulation cable core group comprises the round insulation cable core and four corrugateds insulation cable cores compositions that are arranged at round insulation cable core surrounding of centering, and round insulation cable core is made up of with the A insulating barrier 2-1 being arranged at outside described A wire seven mutually stranded A wire 1-1; Corrugated insulation cable core is by ten mutually stranded B wire 1-2 and be arranged at the B insulating barrier 2-2 group outside described B wire.
4 corrugated type insulation cable cores in the present embodiment, hard-pressed bale is lived middle 1 and is pressed round insulation cable core.Each cable core inner lead adopts that copper free wire is stranded to be formed, single line resistivity complies with the national standard requirements, conductor resistance complies with the national standard requirements equally, conductive performance is better, both met cross-sectional area of conductor long-pending, meet again the ampacity requirement of cable, corrugated cable core inner conductor is stranded by the A wire 1-1 of 10 2.54mm, presses circular cable core inside stranded by the B wire 1-2 of 7 2.14mm.
A insulating barrier 2-1 in the present embodiment and B insulating barrier 2-2, adopt 125 DEG C of irradiation crosslinking halogen-free low-smoke flame-proof polyolefin Insulation Material.Specifications and models are that the model that Hebei Zhonglian Plastic Technology Development Co., Ltd. produces is ZL1214-J-2, column type particle, smooth surface, free from admixture, even particle size, pore-free.This Insulation Material meets that low cigarette, Halogen are nontoxic, fire-retardant, heat-resisting, environmental protection, is crosslinkable through irradiation, and the performance of various aspects is all improved significantly simultaneously.
The design parameter of A insulating barrier and B insulating layer material and test data are as table 1:
In the present embodiment, the rope form that is shaped as of filler 7 is filled.Packing material, mainly, taking strong aluminium oxide, this based flame retardant of magnesium hydroxide as principal component, oxygen index reaches more than 30.
The present embodiment, band 3 adopts fireproof glass silk strap, is formed by the fiberglass braided of high-quality, has than the inorganic and better characteristic of organic fiber.Employing individual layer is wrapped, and the rate of putting up is greater than 50%, and wide is 40mm, and thickness is 0.2mm.When its hot strength N/35mm >=500, smoke density %≤120, oxygen index % >=55, burning, emit pH value >=4.3, conductance μ s/mm≤3.0 of etchant gas, closely envelope the insulated wire cores after stranding, reach the more effect of rounding, have fire-retardant performance, the common band of the Performance Ratio of tension stress and extensibility is better simultaneously.
The present embodiment extrudes lining, uses flame-proof polyvinyl chloride material, and the core after stranding is better coated, reaches the effect of rounding more.While preventing from being wound around armour, strip material causes damage to insulated wire cores simultaneously.Select fire proofing, the flame retardant effect being better issued in specific environment for use.
The steel belt layer 5 of the present embodiment, adopts double-deck winding, and the rate of putting up exceedes 50%.Select through stainless steel compound belt anticorrosion, antirust processing.The anti-tensile ability of this steel band and impact resistance are all greatly improved than common chromium plating composite steel band and common steel band.From intensity relatively, the surrender of special termite-proof composite steel band is measured by force to improve and is exceeded 20%, like this by the ability that improves greatly cable shock resistance and bite.Although the resistance to corrosion of normal conventional chromium plating steel band also possesses, but under mouse group bites, the coating at edge is probably destroyed, thereby cause local by the mouse group destruction that bites, therefore the utility model is selected the steel band that corrosion resistance is stronger, thereby reaches the requirement of technical indicator.
The termite-proof oversheath 6 of the present embodiment, uses 90 DEG C of termite-proof protective cover materials of thermoplastic halogen-free and low-smoke flame-retardant polyolefin.Use 90 DEG C of termite-proof protective cover materials of thermoplastic halogen-free and low-smoke flame-retardant polyolefin.Specifications and models are ZL1112-HY(Hebei Zhonglian Plastic Technology Development Co., Ltd.), this material is cylindrical particle, smooth surface, free from admixture, even particle size, pore-free.Outstanding characteristic, termite-proof, anti-light aging.These performances, in testing process, have all obtained embodiment, meet national standard, and some projects exceed national requirements.Specifically in table 2:
In the present embodiment, adopt four this arrangement architectures of corrugated insulation cable core parcel round insulation cable core can make cable rounding more, 1 round insulation cable core of 4 corrugated insulation cable core parcels is compacter, and the outside diameter of cable is less, saves the consumption of protective cover material.
As shown in Figure 2, with accompanying drawing 1 difference be in termite-proof oversheath 6 outer setting ICr
18ni
9ti stainless steel stratum reticulare 8, has increased and has put stinging property, and due to this special quality, does not affect the flexibility of cable.And do not affect the outside giving forth fragrance of anti-ant oversheath.
The above execution mode is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the present invention.For persons skilled in the art, any apparent change of under the prerequisite that does not deviate from the utility model principle and spirit, it having been done, within all should being contemplated as falling with claim protection range of the present utility model.
