Abstract
The invention discloses a fireproof ceramic cable which comprises a conductor, an insulating layer, a ceramic layer and a sheath, wherein the insulating layer wraps the conductor, the ceramic layer wraps the insulating layer, and the sheath wraps the ceramic layer. Because the ceramic layer is arranged, a circuit maintains integrity after fire resistance is purely carried out for 180 minutes; in a fireproof waterproof test, water is sprayed after the cable is under fire for 15 minutes, then the cable continues to be under fire for 15 minutes, and the circuit maintains integrity; in a fireproof impact resistance test, the circuit still maintains integrity after being suffered from fire and impact. The fireproof ceramic cable is good in fire resistance, water resistance and impact resistance and capable of being applied to power supplying for elevators, emergency devices and the like of high-rise buildings.
Description
Technical field
The present invention relates to a kind of improvement of cable, refer in particular to a kind of fire-resistant, waterproof, impact-resistant ceramic fireproof cable.
background technology
Cable of the prior art is when breaking out of fire, protective layer outside conductor can be because overdo, and it is ineffective, thereby initiation short circuit, making provides the equipment of power supply to work by cable, if by this cable application in occasions such as the elevator of high-rise building, emergency sets, when breaking out of fire, can because elevator, emergency set can not work and cause larger injures and deaths; In order to guarantee that elevator, emergency set can be tried one's best when the breaking out of fire, work for a long time, we have researched and developed a kind of fire-resistant, waterproof, impact-resistant ceramic fireproof cable.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of fire-resistant, waterproof, impact-resistant ceramic fireproof cable.
For achieving the above object, the technical solution used in the present invention is: a kind of ceramic fireproof cable, comprises conductor, insulating barrier, ceramic layer, sheath; Described insulating barrier is wrapped in outside conductor; Described ceramic layer is wrapped in outside insulating barrier; Described sheath parcel ceramic layer.
Preferably, between described sheath and ceramic layer, be provided with fire guard.
Preferably, described fire guard, comprises base material, on described base material, divides and is not furnished with granular mineral matter.
Preferably, described ceramic layer is made by ceramic-rubber, and described ceramic-rubber comprises pottery, rubber; By mass percentage: pottery accounts for 30-40%; Described rubber accounts for 60-70%.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Ceramic fireproof cable of the present invention, owing to being provided with ceramic layer, after fire-resistant 180 minutes, circuit keeps complete merely; Fire-resistant waterproof test, is sprinkled water after 15 minutes by fire and continues to be subject to fire after 15 minutes, and it is complete that circuit keeps; Fire-resistant impulse withstand test, is subject to fire and impacts circuit after 15 minutes to keep complete; The present invention is fire-resistant, waterproof, shock-resistant good, can be cable application in power supplies such as the elevator of high-rise building, emergency sets.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The schematic diagram that accompanying drawing 1 is ceramic fireproof cable of the present invention;
Wherein: 1, conductor; 2, insulating barrier; 3, ceramic layer; 4, fire guard; 5, sheath.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is a kind of ceramic fireproof cable of the present invention, comprises conductor 1, insulating barrier 2, ceramic layer 3, sheath 5; Described insulating barrier 2 is wrapped in outside conductor 1; Described ceramic layer 3 is wrapped in outside insulating barrier 2; Described sheath 5 parcel ceramic layers 3; Between described sheath 5 and ceramic layer 3, be provided with fire guard 4.Described fire guard 4, comprises base material, on described base material, divides and is not furnished with granular mineral matter; Described ceramic layer 3 is made by ceramic-rubber, and described ceramic-rubber comprises pottery, rubber; By mass percentage: pottery accounts for 30-40%; Described rubber accounts for 60-70%; Ceramic-rubber in described ceramic layer 3 can form hard pottery after meeting fire; Before not overdoing, there is certain pliability, convenient wiring.
Ceramic fireproof cable of the present invention, owing to being provided with ceramic layer, after fire-resistant 180 minutes, circuit keeps complete merely; Fire-resistant waterproof test, is sprinkled water after 15 minutes by fire and continues to be subject to fire after 15 minutes, and it is complete that circuit keeps; Fire-resistant impulse withstand test, is subject to fire and impacts circuit after 15 minutes to keep complete; The present invention is fire-resistant, waterproof, shock-resistant good, can be cable application in power supplies such as the elevator of high-rise building, emergency sets.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
