Description
Technical field
The utility model is related to field of cable technology, specifically a kind of adiabatic insulated cable of copper sheath mineral.
Background technology
Electric wire can be used in various architectural engineerings, be widely used.At present, electric wire mainly uses plastics or rubber
Insulation, when running into high temperature or fire, insulating barrier can be melted, destroyed, and cause electric wire short circuit power-off, and produce poisonous, strong
Corrosive gas and dense smoke, jeopardize the person and property safety, also can severe contamination environment, especially in the complexity such as such as mining site, ring
Under conditions of border is severe, the safety in utilization of cable is more exposed to attention, therefore a kind of cable with copper sheath is because of its corrosion resistant
Erosion, fire line etc. are widely used.And because copper product has very high thermal conductivity factor, therefore thermal conductivity is good, at some
Under the higher condition of work of temperature, when such as occurring fire, copper pipe can absorb heat and conduct heat to cable inner insulating barrier
Or on conductor, conductor heat conductivility is reduced, it is also possible to causing insulating barrier or cable jacket etc. to melt in the case that temperature is too high,
Electric leakage is caused, life safety is threatened.
Utility model content
The purpose of this utility model is to provide a kind of copper sheath mineral adiabatic insulated cable, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：
A kind of adiabatic insulated cable of copper sheath mineral, including：Conductor, electro-insulating rubber layer, cable jacket, Ceramic silicon rubber
And copper sheath, the conductor is arranged in electro-insulating rubber layer, and the electro-insulating rubber layer has three groups, is uniformly arranged on cable jacket
It is interior, magnesium oxide mineral insulation powder is filled with cable jacket；The Ceramic silicon rubber is arranged on cable jacket periphery, ceramic
Cavity is left between silicon rubber and cable jacket, the cavity is is evacuated in closed cavity and its, the copper sheath is set
Fit in Ceramic silicon rubber periphery and with Ceramic silicon rubber, be circumferentially uniformly arranged in the copper sheath some long along cable
Spend the water pipe in direction.
It is used as further program of the utility model：Valve is set outside the copper sheath, and valve is connected with cavity, outside valve
External screw thread provided circumferentially about.
It is used as further program of the utility model：Set and set in closure, the closure and outer on the valve
The internal thread that screw thread is meshed.
It is used as further program of the utility model：The cable jacket is made of polytetrafluoroethylplastic plastic.
It is used as further program of the utility model：The cavity sets one on longitudinally along the cable per 1.5-2m
Individual, each cavity is equipped with a valve and closure.
Compared with prior art, the beneficial effects of the utility model are：The utility model is to existing mineral insulated cable
It is improved, using setting cooling water in copper sheath and the mode of vacuum chamber being set in cable, is inhaled respectively by cooling water
Heat and the mode of vacuum heat-insulation prevent heat from conduct into cable conductor, realize effectively adiabatic, it is ensured that cable work reliability with
Stability, extends cable service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of adiabatic insulated cable of copper sheath mineral, including：Conductor 10,
Electro-insulating rubber layer 9, cable jacket 7, Ceramic silicon rubber 5 and copper sheath 4, the conductor 10 are arranged in electro-insulating rubber layer 9, institute
Stating electro-insulating rubber layer 9 has three groups, is uniformly arranged in cable jacket 7, and magnesium oxide mineral insulation powder 8 is filled with cable jacket 7,
It can ensure that cable insulation is good, and stability is reliable, is difficult to be destroyed；The Ceramic silicon rubber 5 is arranged on cable jacket 7
Periphery, leaves cavity 6 between Ceramic silicon rubber 5 and cable jacket 7, the cavity 6 be closed cavity and its in be evacuated,
The copper sheath 4 is arranged on the periphery of Ceramic silicon rubber 5 and fitted with Ceramic silicon rubber 5, circumferentially equal in the copper sheath 4
Cooling water is marked with some water pipes 3 longitudinally along the cable of even setting, water pipe 3, when copper sheath 4 absorbs outside heat, meeting
By substantial amounts of heat transfer into cooling water, the temperature that can be so prevented effectively from copper sheath 4 is too high, is set in copper sheath 4
Ceramic silicon rubber 5, heat resistance is very strong, can bear to be evacuated in more than 200 degrees Celsius of high temperature, cavity 6, and lacking in it can
Can not be transferred to the heat in the air of heat conduction, therefore copper sheath 4 and Ceramic silicon rubber 5 inside cable conductor, realize every
The purpose of Thermal protection conductor 10.
The copper sheath 4 is outer to set valve 2, and valve 2 connects with cavity 6, sets external screw thread on the excircle of valve 2, can connect
