Abstract
The invention discloses a fireproof cable, which consists of a cable core and a sheath, wherein the sheath internally comprises an autohension fireproof wrapping tape used for replacing a lining layer arranged in the sheath in the cable. Compared with the prior art, the fireproof cable disclosed by the invention is characterized in that accident fire caused by self-ageing of the cable due to the installation environment and artificial destruction can be scientifically solved. Meanwhile the fireproof cable is connected with an alarm system and gives an alarm once a line is on fire, and therefore, unnecessary trouble and loss can be avoided.
Description
Technical field
The present invention relates to a kind of communication cable, specifically a kind of for fireproof cable.
Background technology
The fireproof cable that occurs on the market at present is to be coated with the last layer fireproof paint by the surface at cable mostly; because cable will be through dragging, drawing in the process of setting up; coating with the surface wears away easily; simultaneously because the difference of installation environment also can cause in various degree damage to cable; for example cable is installed in the wall; coating can be wiped off by wall in the process that pulls; if cable unit underground; through moisture with the destruction of some biologies; also easily the coating of cable surface is got rid of, thereby lost flameproof protection.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of fireproof cable in order to solve the deficiencies in the prior art.
Technical scheme: in order to realize above purpose, it comprises cable core, insulating barrier, sheath a kind of fireproof cable of the present invention, described sheath comprises fire prevention band, sheath, described cable core is insulated layer parcel, described fire prevention band is located at the insulating barrier outer surface, and described sheath is wrapped in respectively cable core, fire prevention band outer surface.
Described sheath comprises sheath and outer jacket, and wherein sheath comprises the cable core belting layer, and described outer jacket comprises screen and armouring.
Described cable core covering is wrapped between cable core and the insulating barrier.
Described screen is located between insulating barrier and the fire prevention band.
Beneficial effect: fireproof cable of the present invention, have the following advantages: compared with prior art, added one deck fire prevention band in this cable inside, prevent from outside artificial ruining cable with baked wheaten cake, also avoid simultaneously the kindling material of cable self, can effectively prevent in transportation, installation process the damage to the cable fire-proof band simultaneously.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
Embodiment
A kind of fireproof cable as shown in the figure, it comprises cable core 1, insulating barrier 2, sheath 3, described sheath 3 comprises fire prevention band 4, sheath 5, described cable core 1 is insulated layer 2 parcel, described fire prevention band 4 is located at insulating barrier 2 outer surfaces, and described sheath 5 is wrapped in respectively cable core 1, fire prevention band 4 outer surfaces.
Described sheath 5 comprises sheath and outer jacket; wherein sheath is for being cable core belting layer 6; outer jacket comprises screen 7 and armouring 8; described cable core belting layer 6 be wrapped in cable core 1 around; described fire prevention band 4 is wrapped between insulating barrier 2 and the screen 7; fire prevention band 4 can prevent effectively that environment is to naturally damaging that cable causes; also can avoid simultaneously in the unintentionally artificial destruction of transporting and installation process causes; screen 7 can effectively stop the electromagnetic wave around the cable that cable is impacted; described screen 7 is located at the inboard of armouring 8; armouring 8 is protected cable from outermost layer; prevented that the people from deliberately destroying cable, can prevent also that with armouring 8 terrestrial life from causing breaking-up to cable therewith.
