These characteristics of the present utility model and advantage will be below embodiment, accompanying drawing in detailed exposure.
[description of drawings]
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model.
[embodiment]
The utility model provides a kind of heat-resistant fireproof wear-resisting optical cable, comprises some cable cores and the protective sleeve that coats described some cable cores, and described cable core comprises stainless-steel tube and coat the ceramic fire resistant layer of this stainless-steel tube that described ceramic fire resistant layer is provided with the mica heat insulating belt outward.Utilize the excellent heat insulation and resistance to elevated temperatures of pottery, make optical cable have excellent insulating refractory function; Mica is the poor conductor of heat, and the mica heat resisting temperature is very high.So the mica heat insulating belt also can strengthen effect of heat insulation.
Be explained and illustrated below in conjunction with the accompanying drawing of the utility model embodiment technical scheme to the utility model embodiment, but following embodiment is preferred embodiment of the present utility model only, is not whole.Based on the embodiment in the embodiment, those skilled in the art belong to protection domain of the present utility model at lower other embodiment that obtains of the prerequisite of not making creative work.
With reference to figure 1, shown in the wear-resisting optical cable of a kind of heat-resistant fireproof, comprise cable core, cable core outer cladding ceramic fire resistant layer 3, ceramic fire resistant layer 3 outer cladding mica heat insulating belt 4, outermost coats protective sleeve 5.The ceramic fire resistant layer plays fire-resistant, heat insulation effect, improves the insulating refractory performance of optical cable; The mica heat insulating belt improves further that optical cable is heat insulation, fire performance and can prevent that stupalith from coming off, and improves the structure of optical cable and the stability of performance.
Above-mentionedly only be a kind of scheme wherein, protective sleeve 5 is interior in concrete the application can arrange some cable cores, and each cable core comprises stainless-steel tube 1 and coats the ceramic fire resistant layer 3 of this stainless-steel tube, the ceramic fire resistant layer 3 outer mica heat insulating belt 4 that arranges.Described stainless-steel tube 1 adopts argon arc welding to be welded, and is indeformable in crooked situation with being heated, and can protect well the safety of optical fiber, farthest guaranteed the transfer function of optical cable.Described stupalith adopts the high voltage package coating process to be coated on the steel pipe outside after crushing evenly and forms ceramic fire resistant layer 3, and ceramic fire resistant layer 3 outer wrapped mica heat insulating belt 4 cause ceramic fire resistant layer close structure behind high-temperature baking.
