And the outer sheath and the isolation layer are divided by the support to achieve the heat insulation effect, so that the heat resistance of the cable is further enhanced, the design is reasonable, the practicability is high, and the cable is worthy of production and popularization.
Description
Technical Field
The utility model relates to the technical field of cables, especially, relate to a flexible mineral insulated cable of isolated form.
Background
Mineral insulated cables (mineral insulated cables) are abbreviated as MI cables, and are used as wiring cables in the domestic practice of mineral cables or mineral fireproof cables.
When the existing mineral insulated cable is used, most of the mineral insulated cables are poor in heat dissipation performance, so that the heat at a certain position is easily too high, and if good heat dissipation is not achieved, the cable is extremely easy to damage, so that safety accidents are caused, the practicability is not strong, and the mineral insulated cable is worth improving.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists the relatively poor grade of most heat dispersion among the prior art, and the flexible mineral insulated cable of isolated form that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the design is an isolated flexible mineral insulated cable which comprises three cable cores, wherein insulating layers are arranged on the outer sides of the three cable cores, an isolating layer is sleeved on the outer side of each insulating layer, a hollow frame is arranged between each insulating layer and each cable core and is of a triangular structure, the three cable cores are divided and filled with filling layers by the hollow frame, heat conducting layers are filled on the inner sides of the hollow frames, an outer sheath is sleeved on the outer side of each isolating layer, a support is arranged between each outer sheath and each isolating layer, and copper columns are embedded in the end faces of the outer sheaths.
Preferably, the heat conducting layer is heat conducting silicone grease.
Preferably, the filling layer is an alkali-free glass fiber bulked yarn layer filled with graphene particles.
Preferably, the insulating layer is formed by wrapping a mica tape.
Preferably, a reflective layer is sprayed on the outer side of the outer sheath.
The utility model provides a pair of flexible mineral insulated cable of isolated form, beneficial effect lies in: the utility model discloses in cut apart three cable cores of group through the hollow frame that sets up, for current intertwine's mode, the effectual thermal production that has reduced, simultaneously through the heat-conducting layer that sets up, can carry out even transmission with the heat, avoid the problem that inside certain department of cable heat too high leads to the damage. And the outer sheath and the isolation layer are divided by the support to achieve the heat insulation effect, so that the heat resistance of the cable is further enhanced, the design is reasonable, the practicability is high, and the cable is worthy of production and popularization.

In the figure: 1. a cable core; 2. an insulating layer; 3. an isolation layer; 4. a hollow frame; 5. a heat conductive layer; 6. a filling layer; 7. an outer sheath; 8. a support; 9. a copper pillar; 10. a light reflecting layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a flexible mineral insulated cable of isolated form, including three cable cores 1, the outside of three cable cores 1 is provided with insulating layer 2, the outside cover of insulating layer 2 is equipped with isolation layer 3, be provided with hollow frame 4 between insulating layer 2 and the cable core 1, hollow frame 4 is the triangle-shaped structure, hollow frame 4 is cut apart three cable cores 1 mutually and is filled there is filling layer 6, the inboard packing of hollow frame 4 has heat-conducting layer 5, the outside cover of isolation layer 3 is equipped with oversheath 7, be provided with support 8 between oversheath 7 and the isolation layer 3, it has copper post 9 to embed on the terminal surface of oversheath 7.
More specifically, the heat conductive layer 5 is heat conductive silicone grease.
Further, the method is described. The filling layer 6 is an alkali-free glass fiber bulked yarn layer filled with graphene particles, and the insulating layer 2 is formed by wrapping mica tapes.
It is worth noting that the outside spraying of oversheath 7 has reflector layer 10, and the reflector layer 10 through the setting is used for the reflection to light to reduce the inside temperature of cable, the utility model discloses in can adopt the reflective paint spraying in the outside of oversheath 7.
The utility model discloses in cut apart three cable cores 1 of group through the hollow frame 4 that sets up, for current intertwine's mode, the effectual thermal production that has reduced, simultaneously through the heat-conducting layer 5 that sets up, can carry out even transmission with the heat, avoid the inside certain heat of cable to lead to the problem of damage excessively high. And cut apart oversheath 7 and isolation layer 3 through the support 8 that sets up and play thermal-insulated effect here, further strengthened the heat resistance of this cable, the design is comparatively reasonable, and the practicality is stronger, is worth producing and popularizing.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
