Description
Technical field
The utility model relates to field of cable technology is and in particular to a kind of mineral insulated cable.
Background technology
Mineral insulated cable is as the copper core copper sheath cable insulating, mineral insulated cable by mineral material magnesia powder
It is made up of copper conductor, magnesium oxide, two kinds of inorganic material of copper sheath, possessed that fire resisting, current-carrying capacity be big at present, waterproof, explosion-proof, resistance to
Corruption, mechanical resistant damage, life-span length, Halogen is nontoxic, resistant to overload, copper sheath can make earth lead excellent properties, are typically suitable for
Occasion has important place, power distribution, High-temp. kiln, the metals such as the confession distribution of fire pump, Emergency generator, airport parking lot
Smelting, ship, oil platform, ancient building, library, chemical plant.
Because, in many commercial Application, high pressure resistant is necessary, but current mineral insulated cable meet resistance to
Pressure request aspect is unsatisfactory, and the circular outer diameter of the mineral insulated cable on market is irregular, and sealing is difficult, is easily caused
Gas leaks, and based on this, designs a kind of new mineral insulated cable or necessary.
Content of the invention
For deficiency present on prior art, this utility model purpose is to be to provide a kind of mineral insulated cable,
Structure letter is answered, reasonable in design, and assembling is firm, and electric property is excellent, and more preferably, air-tightness is safe and reliable, practical for resistance to pressure,
Use easy to spread.
To achieve these goals, this utility model is to realize by the following technical solutions: a kind of mineral insulation
Cable, including copper sleeve assembly, core number sleeve pipe, cable body, six square bushings, rustless steel ferrule fitting, six square bushings with
The connection of rustless steel ferrule fitting is located on cable body, and cable body two ends are peeled off and are mounted on copper sleeve on the core of crust
Assembly, core is arranged with core number sleeve pipe, and described copper sleeve assembly is inoculated with metal dust rock with the junction of cable body
Stone solidifies fluid sealant.
Preferably, it is soft to be wound with politef at described rustless steel ferrule fitting and the connection screw thread of six square bushings
Property band.
The beneficial effects of the utility model: stable chemical performance, excellent electrical properties, resistance to high humidity, aging resistance, non-combustible,
Air-tightness is outstanding, can reach 8-9 mpa with pressure-bearing, expands the application of mineral insulated cable so as to practicality increases
By force.
Brief description
To describe this utility model with reference to the accompanying drawings and detailed description in detail；
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Technological means, creation characteristic, reached purpose and effect for making this utility model realize are easy to understand, below
In conjunction with specific embodiment, this utility model is expanded on further.
With reference to Fig. 1, this specific embodiment employs the following technical solutions: a kind of mineral insulated cable, including copper sleeve
Assembly 1, core number sleeve pipe 2, cable body 3, six square bushings 4, rustless steel ferrule fitting 5, six square bushings 4 and rustless steel cutting ferrule
Joint 5 is located on cable body 3 after connecting, and is wound with poly- four at the connection screw thread of rustless steel ferrule fitting 5 and six square bushings 4
Fluorothene flexible sealing band, cable body 3 two ends are peeled off and are mounted on copper sleeve assembly 1 on the core of crust, sheathed on core
There is core number sleeve pipe 2, described copper sleeve assembly 1 is inoculated with metal dust rock solidification fluid sealant with the junction of cable body 3.
The mounting process step of this specific embodiment is: mineral insulated cable is intercepted suitable length by (1)；
(2) with specific purpose tool, the cable body 3 two ends copper crust of mineral cable is peeled off, expose the line of suitable length
Core；
(3) by cable two ends manual grinding rounding to dimensional requirement, and checked with miking；
(4) the rustless steel ferrule fitting 5 of customization is linked together with six square bushings 4, then penetrate the electricity polished
On cable body 3；
(5) the copper sleeve assembly 1 at cable two ends is installed, and fixed；
(6) survey break-make, labelling core sequence number with circuit tester, and put core number sleeve pipe 2；
(7) with curved copper cable instrument, one end of cable body 3 is curved the radius length of requirement；
(8) whether passed through with rectifier measurement cable insulation is pressure；
(9) fill metal dust rock solidification fluid sealant at cable two copper sleeve assembly 1 end, quiet put 12 hours；
(10) pressure with rectifier measurement insulation again, it is qualified to be confirmed whether.
Cable has been carried out accurate polishing by this specific embodiment, and is measured using micrometer, and cable is cylindrical
Polishing accuracy tolerance requires as+0.05-0 the installation accuracy it is ensured that higher, then assembles the special guarantee air-tightness that has and ties
The rustless steel ferrule fitting 5 of structure, through practical proof and continuing to optimize, accurately grasps the installation dimension of ferrule fitting, installs step
Suddenly, machining accuracy, processing technique are so as to reach optimal sealing effectiveness；Reducing by customization rustless steel ferrule fitting 5 and customization
Joint, that is, six square bushings 4 according to technique scheme, assembling is installed, simultaneously using two kinds anti-corrosion, explosion-proof, stable chemical performance,
The special material of easy-clear: politef flexible sealing band solidifies fluid sealant with metal dust rock, reaches the complete of this assembling
Whole sealing effectiveness it is ensured that cable in pressure vessel with pressure vessel outside have pressure differential in the case of, in pressure vessel
Portion's gas leaks without going past any sealing part in this cable, and this kind of mounting technique solution can bear higher pressure
Power is not revealed.
This specific embodiment effectively overcomes existing common explosion-proof flame-retardant armored cable or common explosion proof flame retardant cable to exist
High temperature, high humidity, corrosivity, have compared with high-air-tightness requirement simultaneously again hazardous environment in when using with conventional general anti-explosion cable
The technical barrier that introducing device cooperation is installed, assembling is firm, and electric property is excellent, and air-tightness is safe and reliable, resistance to high humidity, anti-ageing
Change, 8-9 mpa can be reached with pressure-bearing, there is wide market application foreground.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have been shown and described above.One's own profession
