Body, mica belt, restrictive coating.
Preferably, be additionally provided with multiple stretch cords between insulating layer, shielded layer, multiple stretch cords around insulating layer it is circumferential according to
Secondary distribution, stretch cord extend along the length direction of cable, are equipped with several elastic force blocks between two stretch cords of arbitrary neighborhood, several
Elastic force block is sequentially distributed along the length direction of cable, and elastic force block and the stretch cord of its two sides lean.
Preferably, the section of conductor is c-type.
Preferably, conductor is silver-coated copper wire.
Preferably, fire proofing is coated in braiding layer.
Preferably, multiple through-holes are provided in polytetrafluoroethylene ethylene layer, multiple through-holes are sequentially distributed around the circumferential direction of cable core, through-hole
Length direction along cable extends.
Preferably, polytetrafluoroethylene ethylene layer is equipped with illumination region.
In the utility model, heat-resisting quantity can effectively be turned up by the way that polytetrafluoroethylene ethylene layer is arranged.It is silver-plated by utilizing
Copper wire greatly improves the flexibility of cable.
The cable high temperature resistant of the utility model, fire resistance are good, and conductive performance is good, and structure is simple, easy to use.
Detailed description of the invention
Fig. 1 is the schematic cross-section of the utility model.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutual combination；The following will be combined with the drawings in the embodiments of the present invention, to the technical scheme in the embodiment of the utility model into
Row clearly and completely describes, it is clear that and the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", " left side " and " right side "
The orientation or positional relationship of equal instructions is to be based on the orientation or positional relationship shown in the drawings, and being merely for convenience of description, this is practical new
Type and simplified description, rather than the position of indication or suggestion meaning or element must have particular orientation, with specific orientation structure
At and operation, therefore should not be understood as the limitation of the utility model.In addition, term " first ", " second " are used for description purposes only,
It is not understood to indicate or imply relative importance.
Referring to Fig.1, the utility model proposes a kind of reinforced high temperature power cable of braiding, from inside to outside successively include cable
Core, insulating layer 4, shielded layer 5, braiding layer 6, polytetrafluoroethylene ethylene layer 7, cable core include multiple mutually twisted cores, and core is certainly introversive
It outside successively include conductor 1, mica belt 2, restrictive coating 3.
Preferably, multiple stretch cords 8 are additionally provided between insulating layer 4, shielded layer 5, multiple stretch cords 8 are around insulating layer 4
It is circumferentially sequentially distributed, stretch cord 8 extends along the length direction of cable, is equipped with several bullets between two stretch cords 8 of arbitrary neighborhood
