Description
Technical field
The utility model is related to a kind of metal sheath inorganic mineral insulation cable, belongs to field of cable technology.
Background technology
Mineral insulated cable (Mineral Insulated Cable) abbreviation MI cables, can be divided by architectural characteristic at present
It is two kinds of rigidity and flexibility：The invention of rigid mineral insulated cable (BTTYZ) is more early, 19 end of the century Switzerland engineer Arnold
Francois Borel propose the imagination of mineral insulated cable, because rigid mineral insulated cable magnesium oxide powder serves as insulation
Layer, is also easy to produce became uneven phenomenon, and technique slightly mistake will puncture, and drawing copper tubes technique causes that single continuous length is limited,
Natural deficiency in structure design, causes it in performance, produces and the aspect such as lay and all there is certain defect, flexible ore deposit
The process structure of thing insulated cable product is identical with traditional cable, successfully solves magnesia copper pipe mineral insulation
The numerous weak points of product that the production technology of cable is determined, but existing flexible mineral insulation cable, in hot environment
The service life of lower cable shortens as many as 2 times than service life under other cable homes, and the design is in JG/T313-
On the basis of the requirement of 2014 standards, increased mineral thermal insulation layer and protect cable core not to be destroyed in flame combustion, solution uses the longevity
The problem for shortening is ordered, flexible mineral insulation cable service life is improved.
Utility model content
The purpose of this utility model is that and provide a kind of metal sheath inorganic mineral insulation in order to solve the above problems
Cable.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of metal sheath inorganic mineral insulated electro
Cable, is followed successively by conductive copper wire core, binder, mineral thermal insulation layer, oversheath from inside to outside, and the conductive copper wire core is externally provided with inorganic
Mineral synthetic mica tape insulating barrier, the inorganic mineral synthetic mica tape insulating barrier is externally provided with inorganic mineral colored insulating layer, institute
State and filling tape is provided between inorganic mineral colored insulating layer and binder, copper gold is provided between the mineral thermal insulation layer and oversheath
Category sheath.
Preferably, the conductive copper wire core is multiply or single strand configuration.
Preferably, the binder is high temperature resistance non halogen glass fiber tape.
Preferably, the mineral thermal insulation layer is high temperature resistant inorganic mineral composite.
Preferably, the oversheath is low smoke, zero halogen polyolefine material.
Preferably, the filling tape is inorganic mineral material.
The beneficial effects of the utility model are：The fire-resistance property of rigid mineral insulated cable is not only remained, but also is had
The features such as having the unsuitable moisture absorption, therefore insulating properties is more stable, improves proof voltage grade, resistance to voltage levels can reach 1000V, so as to subtract
Lacked it is many because inductance, the frequent starting of frequency conversion electrical equipment and caused by surge voltage, correspondingly cause line system service life
Greatly improve, employ the traditional cable structure such as twisted wire, stranding so that cable is more soft, largely used mineral and mineralized
Compound, has not only saved magnesium resource, has also correspondingly saved substantial amounts of energy resource consumption.
