The utility model is a fire-resistant mineral insulated cable, which includes a conductor, a sheath and an insulating layer. The conductor is tightly covered with a mica insulating tape, and the mica insulating tape is provided with glass fillers. The insulating layer is arranged on Outside the glass filler, the sheath wraps the insulation from the outside of the insulation. Through the above structure, the fire-resistant mineral insulated cable has sufficient flexibility and fire resistance, is easy to process and use, and can be processed into any length according to actual needs. Moreover, the intermediate joints of cables can be reduced, which can greatly save costs.
Description
Technical field
The utility model relates to power cable, a kind of fire safe type mineral insulated cable of saying so exactly.
Background technology
Along with modernization further develops, national to the skyscraper in the big and medium-sized cities, the public place, the power plant that the public place of entertainment is important waits fire protection requirement further strict.The fire safe type mineral insulated cable is in low-voltage distribution system is installed, and is convenient, quick, and economy is safe and reliable, at home and abroad is extensive use of.
But currently used fire safe type mineral insulated cable, as patent application 200920191372.1 is described, normally there are copper core nickel bag conductor and external insulation, sheath to constitute, lack flexibility, if oversize cable is set, then to finish the connection of cable by a lot of transition joints, use and inconvenience.
Summary of the invention
Based on this, the purpose of this utility model provides a kind of fire safe type mineral insulated cable, and this cable has more flexibility, characteristics such as fire resistance and convenient processing.
For achieving the above object, the utility model is achieved in that
A kind of fire safe type mineral insulated cable, it comprises conductor, sheath and insulating barrier, it is characterized in that described conductor outside tightly is coated with the mica insulation band, mica insulation band outside has the glass filler again, insulating barrier is arranged at glass filler outside, and sheath is again from the external packets insulating layer coating of insulating barrier.
By said structure, this fire safe type mineral insulated cable has enough flexibilities and fire resistance, is convenient to processing and uses, and can be processed into length arbitrarily according to actual needs.And can reduce the transition joint of cable, can save cost greatly.
Described conductor has a plurality ofly, and outside all independent packets of each conductor are covered with the mica insulation band.
Described mica insulation band has plural layer, so that it reaches the thickness of regulation, guarantees requirement on electric performance.
Described insulating barrier is the glass belt, by the glass belt glass filler and conductor is coated, and has fire prevention, the insulation effect of replacing.
The outside of described sheath also is provided with anticorrosion oversheath, makes described cable have good antiseptic effect.
Described conductor adopts two classes to press round conductor.Make cable have certain flexibility.
The utility model adopts above-mentioned version, makes the fire safe type mineral insulated cable have more flexibility, fire resistance, and convenient processing and processing are used, and can be processed into length arbitrarily according to actual needs, and can reduce the transition joint of cable, can save cost greatly.
Description of drawings
The structural representation that Fig. 1 implements for the utility model.
Embodiment
Below, in conjunction with the accompanying drawings shown in, concrete enforcement of the present utility model is elaborated.
Shown in Figure 1, specific implementation structure of the present utility model comprises: conductor 1, synthetic mica insulating tape 2, glass are filled silk 3, glass belt 4, copper sheath 5, anticorrosion oversheath 6.
Wherein, conductor 1 adopts two classes to press round conductor.Make cable have certain flexibility; Insulating barrier is changed by inorganic powder into reduce when crooked synthetic mica insulating tape 2 back because the mobile conductor and the copper sheath of causing of powder collided and short circuit.And adopt tightly coating conductor of synthetic mica insulating tape 2, and owing to be combination tightly, appoint the conductor bending, conductor is run into copper sheath.Can not cause short circuit, play more than the inorganic powder inaccessible insulation effect that insulate.
Synthetic mica insulating tape 2 is compounded to form by a plurality of mica insulation bands.
The technical performance of mica insulation band will conform to the regulation of the appendix C of GB/T19666-2005:
Its mica content is greater than 55%, and volatile content is less than or equal to 1%.
Its hot strength is more than or equal to 100N/10mm.
Its power frequency dielectric strength is more than or equal to being 10(normal temperature) MV/m.
Specific insulation is more than or equal to 1.0X1010 Ω .m.
Electrical property proof voltage 1KV under its high temperature.1000 ℃/90min did not puncture in 1 minute, and insulation resistance is greater than or equal 0.4M Ω.
Insulating barrier is a glass belt 4, by glass belt 4 glass is filled silk 3 and conductor 1 coating, has fire prevention, the insulation effect of replacing.
Anticorrosion oversheath 6 adopts low smoke, zero halogen PE oversheath, promptly extrudes one deck low smoke, zero halogen material outside copper sheath 5, and the thickness of low smoke, zero halogen material will reach setting.
Thus, the fire safe type mineral insulated cable realized of the utility model has stable electric property; Fire prevention, fire-resistant, high temperature resistant, the fire resistance of superelevation is arranged; Good mechanical property is installed and is laid conveniently; Decay resistance can be high; The no width of cloth is penetrated, no eddy current, and overload capacity is strong; Flexibility is good, can be used for mobile occasion.
Also can make the heavy in section multicore cable of 400mm2.Single core can be made the 1000mm2 cable.
And has smokeless, nontoxic characteristic.
The above person only is the embodiment that enumerates of the utility model, when the scope that can not limit the utility model enforcement with this.Promptly the equalization of being done according to the utility model claim generally changes and modifies, and all should still belong in the scope that the utility model patent contains.
