Multiple heating conductors are evenly distributed in inside insulating barrier, and each periphery for heating conductor is provided with high temperature resistant heat insulation
Layer；
The interior intracavitary is provided with inner chamber support so that inner chamber is divided into multiple bore passages, and each bore passages pass through
Communicating pipe and connected with exocoel；
The exocoel and the cavity that inner chamber is both ends sealing, it is filled with inert gas.
Further, temperature sensor, the temperature sensor and a report are provided with each bore passages of inner chamber
Alarm device is electrically connected with.
Further, the inert gas that the inner chamber and outer intracavitary are filled with is neon.
Further, offered on the link between the periphery restrictive coating and water-proof jacket layer so that exocoel mutually to be interconnected
Logical multiple stomatas.
Further, it is additionally provided with electro-magnetic screen layer between the water-proof jacket layer and the insulating barrier.
Further, the periphery restrictive coating is halogen-free low-smoke flame retardant material.
Further, the insulating barrier uses magnesium oxide material.
Compared with prior art, the beneficial effects of the utility model are as follows：
The utility model is by setting inner chamber in the inside of heating cable and setting exocoel, inner chamber and exocoel phase in outside
It is intercommunicated, so that the temperature of inner chamber and outer intracavitary Transmit evenly and can be distributed in heating cable periphery, avoid office
Temperature too high situation in portion's occurs；
In addition, being passed through inert gas in inner chamber and exocoel, the hot gas in cavity on the one hand can be conducted, on the one hand may be used
To play a part of preventing fire；
The service life of the utility model heating cable is provided significantly.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
The required accompanying drawing used is briefly described in description, it should be apparent that, drawings in the following description are only that this practicality is new
Wherein two width of type, for those of ordinary skill in the art, without having to pay creative labor, can be with root
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the cross-sectional view of the utility model embodiment；And
Fig. 2 is the side sectional view of the utility model embodiment.

Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only preferred embodiment of the present utility model, rather than whole embodiments.Based in the utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of the utility model protection.
Embodiment
Refer to the attached drawing, Fig. 1 are the cross-sectional view of the utility model embodiment；And Fig. 2 is implemented for the utility model
The side sectional view of example, which show only a part for mineral insulation heating cable.
Mineral insulation heating cable of the present utility model, it includes periphery restrictive coating 1, water-proof jacket layer successively from outside to inside
2nd, insulating barrier 3 and inner chamber 4.By setting periphery restrictive coating and water-proof jacket layer to play the same of duplicate protection to heating cable
When also increase heating cable service life.
Specifically, it is multiple hollow to be divided into that link 5 is provided between periphery restrictive coating 1 and water-proof jacket layer 2
Exocoel 6；Multiple heating conductors 7 are evenly distributed in inside insulating barrier, each periphery for heating conductor 7 be provided with high temperature resistant every
Thermosphere 8；Inner chamber support 9 is provided with inner chamber 4 so that inner chamber is divided into multiple bore passages, preferably four passages, but this is interior
The quantity of chamber passage is not restricted to this.Each bore passages are connected by communicating pipe 10 with exocoel 6（Such as institute in fig. 2
Show, communicating pipe is set spaced apartly）, so as to which inner chamber and exocoel are formed into an interconnected cavity.In reality
Border is in use, exocoel 6 and inner chamber 4 are the cavity of both ends sealing, it is filled with inert gas, by filling inert gas,
Gas can be caused to be flowed between inner chamber and exocoel, so that heating cable heated is uniform, avoid local temperature too high
Situation.In addition, heating cable is easily produced because of situations such as heating conductor aging when long-time uses and is smoldered or caught fire
