Abstract
The utility model discloses a kind of fireproof cable, comprise insulating barrier, watertight composition, rubber layer, thermal insulation layer, aramid layers and flame-retardant expanded layer, described insulating barrier, watertight composition, rubber layer, thermal insulation layer, aramid layers and flame-retardant expanded layer are wrapped on core from inside to outside successively, and aramid layers is netted; The skin of described rubber layer is frosting, and described thermal insulation layer is fitted on the frosting of rubber layer.When the expanded material in flame-retardant expanded layer is when temperature is higher than 200 degree, start foaming, more high-foaming speed is faster for temperature, foaming and intumescing coefficient reaches 20 times, the bubble that expanded material sends has excellent heat-insulating capability, if by fire location, the bubble sent can fill up rapidly near fire location, fire is extinguished due to anoxic.Thus reach the object preventing cable on fire.
Description
Technical field
The utility model relates to field of cables, particularly, relates to a kind of fireproof cable.
Background technology
At present, along with the development of clean energy resource, electric power resource high speed development, along with the construction of nuclear power station, hydroelectric station and wind power generation, cable becomes conventional instrument in life.But because cable is when transmitting electric power, often because the short circuit of connector lug place causes cable on fire, thus cause fire, in electric power remote conveying, adopt bare wire to carry, but in productive life, because of fail safe, the cable with insulating outer layer must be adopted to carry out electric power conveying, and existing cable exist because connector lug short circuit causes the potential safety hazard of fire.
Utility model content
The purpose of this utility model is, for the problems referred to above, proposes a kind of fireproof cable, to realize the advantage preventing cable on fire.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of fireproof cable, comprise insulating barrier, watertight composition, rubber layer, thermal insulation layer, aramid layers and flame-retardant expanded layer, described insulating barrier, watertight composition, rubber layer, thermal insulation layer, aramid layers and flame-retardant expanded layer are wrapped on core from inside to outside successively, and aramid layers is netted; The skin of described rubber layer is frosting, and described thermal insulation layer is fitted on the frosting of rubber layer.
Preferably, the thickness of described insulating barrier is 1 ~ 2mm, and described waterproofing layer thickness is 0.1 ~ 0.4mm, and the thickness of described rubber layer is 0.5 ~ 1.2cm, and the thickness of described thermal insulation layer is 0.09mm.
Preferably, described flame-retardant expanded layer is latticed.
Preferably, described flame-retardant expanded layer is laid in joint 20 meters.
The technical solution of the utility model has following beneficial effect:
The technical solution of the utility model, when the expanded material in flame-retardant expanded layer is when temperature is higher than 200 degree, start foaming, more high-foaming speed is faster for temperature, foaming and intumescing coefficient reaches 20 times, and the bubble that expanded material sends has excellent heat-insulating capability, if by fire location, the bubble sent can fill up rapidly near fire location, and fire is extinguished due to anoxic.Thus reach the object preventing cable on fire.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the fireproof cable sectional elevation described in the utility model embodiment;
Fig. 2 is the structural representation of the fireproof cable described in the utility model embodiment.
By reference to the accompanying drawings, in the utility model embodiment, Reference numeral is as follows:
1-core; 2-insulating barrier; 3-watertight composition; 4-rubber layer; 5-thermal insulation layer; 6-aramid layers; The flame-retardant expanded layer of 7-; 8-joint.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of fireproof cable, comprise insulating barrier 2, watertight composition 3, rubber layer 4, thermal insulation layer 5, aramid layers 6 and flame-retardant expanded layer 7, insulating barrier 2, watertight composition 3, rubber layer 4, thermal insulation layer 5, aramid layers 6 and flame-retardant expanded layer 7 are wrapped on core 1 from inside to outside successively, and aramid layers 6 is netted; The skin of rubber layer 4 is frosting, and described thermal insulation layer 5 is fitted on the frosting of rubber layer 4.
Wherein, the thickness of insulating barrier is adopted as 1 mm, 1.5 mm or 2mm, waterproofing layer thickness can be 0.1 mm, 0.2 mm, 0.3 mm or 0.4mm, and the thickness of rubber layer is 0.5 cm, 0.7 cm, 0.9 cm, 1.1 cm or 1.2cm, and the thickness of thermal insulation layer is 0.09mm.Flame-retardant expanded layer is latticed.Latticedly more be beneficial to foaming.As shown in Figure 2, flame-retardant expanded layer is laid in joint 20 meters.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
