Description
Technical field
This utility model belongs to technical field of electric wires and cables, espespecially a kind of cable, is specifically related to a kind of New Mineral insulated cable.
Background technology
Fast development along with society, various electrical equipment have also been obtained effective development, and connect one important accessory of electrical equipment of cable effect, have also been obtained effective development, the cable of prior art is mainly made up of restrictive coating, conductor and flame retardant coating, although it can realize conducting function to a certain extent, but the cable stability in use of prior art is poor, and shield effectiveness inconspicuous, have impact on the suitability of cable to a certain extent.
Along with the increase of demand, in cable, the diameter of cable conductor is the most increasing, and in order to reach the effects such as insulation and shielding, in addition it is also necessary to wrapped multiple material on conductor, thus cause cable more and more heavier, more and more inconvenient during installation;In order to reduce lapping and cost of manufacture, overwhelming majority cable of the prior art has cannot possess stronger high temperature-proof effect, and security performance is poor, is therefore unfavorable for being widely used.
Utility model content
For above-mentioned weak point of the prior art, the purpose of this utility model is intended to provide a kind of rational in infrastructure, and easy to use, security performance is high, have simultaneously stronger fire line cable.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions:
A kind of New Mineral insulated cable, including overcoat and cable core, described overcoat is arranged at outside cable core, described cable core is formed by some metal catheters circumference is stranded, every metal catheter is made up of zinc-plated copper wire, cable core outer rim parcel is provided with fireprotection layer, is provided with packed layer and reinforcement between described fireprotection layer and setting and overcoat, and described packed layer material is lightweight stone ore；Described overcoat uses double-decker arrange and be internally provided with securing member and dead ring, and described dead ring is provided with some securing members.
Further preferably, overcoat uses insulant to be mixed with steel and forms, and described insulant is low-smoke halogen-free polyolefin or polyethylene.
nullSpecifically，This utility model technology is used to reach to reduce cable integral manufacturing cost by reducing jacket internal adding layers quantity，It is socketed fireprotection layer in cable core outer rim simultaneously，Owing to the relation once cable core generation condition of a fire fireprotection layer of fireprotection layer 3 can control fire spreading，Improve cable overall security，Fireprotection layer 3 is the insulated wire cores thermal insulation layer of high molecular halogen-free silicon porcelain cement，For cable core is separated with external heat edema caused by disorder of QI，Play fire prevention、Moistureproof、Heat insulation and waterproof effect，The integrity of the metallic conductor in cable core can be protected and play waterproof effect，High molecular halogen-free silicon porcelain cement makes by pressing formula fashion of extrusion，Fireprotection layer is arranged between cable core outer surface，Make in case of fire，When ambient temperature reaches more than 650 DEG C，This fireprotection layer starts carbonization，Under overcoat is protected，Cable core can be fixed after this fireprotection layer 3 carbonization，And effectively cable core and external heat air bound are opened，Play the integrity of protection metallic conductor，Protection cable is the most short-circuit，Not open circuit，Thus ensure that the unobstructed of circuit；Fireprotection layer can effectively completely cut off core heat, reduces sheath temperature, and when cable core is operated in temperature 125 DEG C, outer jacket temperature is within 75 DEG C, and operating temperature 150 DEG C, outer sheath temperature is within 88 DEG C；Furthermore, owing to being provided with packed layer at space between fireprotection layer and overcoat and packed layer material is that lightweight stone ore not only makes the intensity of a fire cannot spread to additionally aid and put out the intensity of a fire, there is stronger fire line；Coordinate with dead ring reinforcement 7 to enable to the raising of cable entire compression finally, due to jacket internal is provided with securing member simultaneously, thus increase the service life.
Further preferably, described reinforcement quantity at least 2 and relative to cable core axis circular array extruding be arranged between overcoat and cable core.
Further preferably, described securing member circularizes array and is arranged at jacket internal and arranges and fixing with dead ring be connected.
This utility model has the advantage that relative to prior art
This utility model in use, has stronger fire prevention high temperature-proof, extends cable whole service life, and cost of manufacture is reasonable simultaneously, has stronger crushing resistance；Therefore, in sum, this utility model has stronger operability, it is simple to be widely popularized universal use.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment, the accompanying drawing used required in embodiment will be done simple introduction below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art under not making creative work premise, the every other embodiment obtained, broadly fall into this utility model protection domain.
A kind of New Mineral insulated cable as shown in Figure 1, including overcoat 1 and cable core 2, described overcoat 1 is arranged at outside cable core 2, described cable core 2 is formed by some metal catheters circumference is stranded, every metal catheter is made up of zinc-plated copper wire, cable core 2 outer rim parcel is provided with fireprotection layer 3, is provided with packed layer 4 and reinforcement 7 between described fireprotection layer 3 and setting and overcoat 1, and described packed layer 4 material is lightweight stone ore；Described overcoat 1 uses double-decker to arrange and is internally provided with securing member 5 and dead ring 6, and described dead ring 6 is provided with some securing members 5.
