Description
Technical field
This utility model relates to a kind of fireproof cable.
Background technology
The position that cable uses is a lot, has buried cable, also has the cable of aerial erection, also has the electricity that sewer is arranged
Cable, these cables mostly use PVC material due to outer layer, and therefore if it occur that fire, cable will be ignited, and causes whole electricity
Cable burns, and affects city and normally uses, and maintenance replacement cost is high, relatively time-consuming.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of by arranging fireprotection layer in inside, effectively plays electricity
Cable fireproof purpose, and the purpose of heat radiation can be effectively played at fireproof simultaneously, it is independent of each other, designs rational in infrastructure, use
The fireproof cable that life-span is more long.
This utility model is achieved through the following technical solutions: a kind of fireproof cable, including outer layer protective layer and
The cable core being arranged in protective layer, described protective layer inner wall even distribution is provided with more than one positioning jack, outside cable core
Portion is just respectively provided with a support bar to each positioning jack；
Support bar one end connects cable core, and the other end inserts and is arranged in positioning jack, described protective layer and cable core it
Between be provided with fireprotection layer, fireprotection layer medial surface is provided with one layer of thermal insulation layer, between thermal insulation layer and cable core formed one heat radiation cavity.
As preferably, described fireprotection layer includes the first fireprotection layer and the second fireprotection layer, the first fireprotection layer and the second fireprotection layer
Between form a filling chamber, fill intracavity and fill earth, earth fills full whole filling chamber.
As preferably, described fireprotection layer being just correspondingly arranged on through hole to each positioning jack, support bar is through through hole extremely
In positioning jack.
As preferably, described support bar uses aluminum heat-removal bar, and the heat on cable core is passed to protective layer by support bar
Heat radiation.
As preferably, described first fireprotection layer and the second fireprotection layer all use tinfoil material to make, the first fireprotection layer and
Two fireprotection layers are provided with more than one layer.
The beneficial effects of the utility model are: this utility model simple in construction, by arranging fireprotection layer in inside, effectively rise
To the purpose of cable fire-proof, and the purpose of heat radiation can be effectively played at fireproof simultaneously, be independent of each other, design rational in infrastructure,
Service life is more long.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
It is protective layer that coding in figure is respectively as follows: 1, and 2 is support bar, and 3 is the first fireprotection layer, and 4 is earth, and 5 is cable core,
6 is the second fireprotection layer.
Detailed description of the invention
As it is shown in figure 1, this fireproof cable, including the protective layer 1 of outer layer and the cable core 5 that is arranged in protective layer 1, described
Protective layer 1 inner wall even distribution is provided with more than one positioning jack, and the outside of cable core 5 is just respectively provided with one to each positioning jack
Support bar 2；
Support bar 2 one end connects cable core 5, and the other end inserts and is arranged in positioning jack, described protective layer 1 and cable core
Being provided with fireprotection layer between 5, fireprotection layer medial surface is provided with one layer of thermal insulation layer, forms a heat radiation sky between thermal insulation layer and cable core
Chamber.
In the present embodiment, fireprotection layer includes the first fireprotection layer 3 and the second fireprotection layer 6, the first fireprotection layer 3 and the second fireprotection layer
Forming a filling chamber between 6, fill intracavity and fill earth 4, earth 4 fills full whole filling chamber, and earth passes through the first fireprotection layer
Isolating with 3 second fireprotection layers 6, earth selects the earth that moisture is few as far as possible, prevents seepage, arranges earth by inside, when
During breaking out of fire, playing a fireproof purpose by the first fireprotection layer 3 and the second fireprotection layer 6, internal earth is for heat insulation
And fire-retardant effect.
Owing to innermost layer is provided with thermal insulation layer, even if outer surface temperature is the highest, the inside also will not be transferred heat to
Cable core, does not interferes with the normal use of cable core, as much as possible protects cable.
Wherein, fireprotection layer being just correspondingly arranged on to each positioning jack through hole, support bar 2 is through through hole to positioning jack
In, support bar 2 uses aluminum heat-removal bar, and the heat on cable core is passed to protective layer 1 and dispels the heat by support bar 2.Support bar 2 has two
Individual effect, first is for supporting cable core 5 so that cable core can soar uniformly and be arranged at the centre of protective layer
Place, second effect being then to play a protective layer 1 that the heat on cable core 5 is passed to outside, inhaled by support bar 2
The substantial amounts of heat of heat, and dispelled the heat by protective layer 1, avoid fireprotection layer, thermolysis can be played again at fireproof simultaneously.
First fireprotection layer 3 all uses tinfoil material to make with the second fireprotection layer 6, and the first fireprotection layer 3 is equal with the second fireprotection layer 6
Being provided with more than one layer, tinfoil is difficult to be burned out, it is possible to strive for that the abundant time goes fire extinguishing for cable, and support bar 2 is aluminum
Bar processed, will not catch fire.
The beneficial effects of the utility model are: this utility model simple in construction, by arranging fireprotection layer in inside, effectively rise
To the purpose of cable fire-proof, and the purpose of heat radiation can be effectively played at fireproof simultaneously, be independent of each other, design rational in infrastructure,
Service life is more long.
