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.
The cable in the market with fire protecting performance is broadly divided into three classes, one is that glass fiber strap built up mica sheet is wrapped in copper cash outer surface as fireprotection layer, this cable fire-proof poor performance, the fire prevention temperature of product and fire resistance period cannot arrive the design specification of modern high-rise building, and the glass fiber of outer layer fire protecting performance when high temperature is poor simultaneously；Another kind is to use mineral powders as the rigid fireproof cable of insulating barrier, and this cable outer layer is copper pipe, lays rigid fireproof cable, complex process, and production difficulty is big, produces and use cost is higher, and bending property is poor, installs and constructs relatively difficult；Last one is silicon rubber insulated cable, and silicone rubber fireproof temperature is low, and therefore fire protecting performance is poor, and breaking out of fire can discharge toxic gas.
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, laying performance is good, has the heat insulation type mineral insulated cable of stronger fire line simultaneously.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions:
A kind of heat insulation type mineral insulated cable, including overcoat and cable core, described jacket internal is provided with cable core；Being provided with thermal insulation layer and packed layer between described overcoat and cable core, described thermal insulation layer outer rim contacts with outer casing inner wall, and described thermal insulation layer outer rim is provided with anti-slip veins and matches with outer casing inner wall；Arranging some metallic conductors inside described cable core, described metallic conductor spiral winding is rounded, and described cable core outer rim is provided with enhancement Layer, and described enhancement Layer inwall contacts with cable core outer rim, and described overcoat outer rim is provided with soft adjustment layer.
Further preferably, described cable core quantity is at least 1, being filled with packed layer between cable core, described packed layer is glass fiber layer, and implant 3 uses glass fibre, not firing of glass fibre, anti-corruption, heat insulation, sound-proofing good, tensile strength is high, the characteristic that electrical insulating property is good, does not interferes with the fire performance of product in fire hazard environment.
Specifically, thermal insulation layer is the insulated wire cores thermal insulation layer of macromolecule silicon halogen-free material, 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 of cable core internal layer can be protected and play waterproof effect, macromolecule silicon Halogen makes by pressing formula fashion of extrusion, thermal insulation layer is arranged between multiple cable core outer surface, make in case of fire, when ambient temperature reaches more than 650 DEG C, this thermal insulation layer starts carbonization, under overcoat is protected, cable core can be fixed after this thermal insulation layer carbonization, and effectively fire-proof insulation 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；Thermal insulation layer can effectively completely cut off core heat, reduces sheath temperature, and when cable core is operated in temperature 125 DEG C, outer sheath temperature is within 75 DEG C, and operating temperature 150 DEG C, overcoat 1 temperature is within 88 DEG C.
Further preferably, described enhancement Layer outer rim is provided with anti-slip veins and matches with cable core inwall, and enhancement Layer is metal level, increases the frictional force between cable core, prevent from coming off while improving cable core intensity.
Further preferably, outside longitudinally staggered soft adjustment layer and the fluorescence coating of being provided with of described overcoat, described soft adjustment layer internal diameter is less than fluorescence coating internal diameter, and in use, cable bend is more convenient, can make warning at night simultaneously, improves cable safety.
This utility model has the advantage that relative to prior art
This utility model in use, has stronger fire line, and laying performance is good simultaneously, widely applicable；Therefore, in sum, this utility model has stronger operability, it is simple to be widely popularized universal use.
