Abstract
The utility model discloses a kind of fireproof cable, comprise 1 ~ 5 copper core (1), fire prevention mica layer (2) is outside equipped with described every root copper core (1), described 1 ~ 5 copper core (1) is arranged in copper pipe (3), between described copper core (1) and fire prevention mica layer (2), be provided with the belt A(4 that prevents fires).The utility model has the advantage that structure is simple, fire protecting performance is good, adopts it not only can improve fireproofing of cable performance, but also reduces difficulty of construction, facilitate operation, the scope of application is larger, when the less position of radius is installed, prevent the damage of copper pipe, reduce potential safety hazard.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of fireproof cable.
Background technology
In existing fireproof cable, its structure mainly comprises 1 ~ 5 copper core, mica layer is surrounded with outside every root copper core, then 1 ~ 5 copper core is coated in copper pipe, the inwall of copper pipe is provided with mica layer, such fireproof cable is mainly stored in following deficiency: 1. fire protecting performance is poor, and be easily short-circuited phenomenon, causes the transmission cannot carrying out electric current; 2. owing to adopting copper pipe to carry out coated, and copper pipe is straight tube, make when carrying out turning position and installing, difficulty of construction is strong, simultaneously, because the bending radius of straight tube is less, when the position that radius is less is installed, easily make copper pipe be out of shape, damage, cable is caused to make moist, electrical property declines, and fire protecting performance reduces greatly, adds potential safety hazard.
Utility model content
The purpose of this utility model is just to provide the good fireproof cable of a kind of fire protecting performance.
The purpose of this utility model is realized by such technical scheme, a kind of fireproof cable, comprises 1 ~ 5 copper core, is outside equipped with fire prevention mica layer at described every root copper core, described 1 ~ 5 copper core is arranged in copper pipe, between described copper core and fire prevention mica layer, be provided with the belt A that prevents fires.
In order to improve fire protecting performance further, be outside equipped with fire prevention belt B at described fire prevention mica layer.
In order to increase fire protecting performance, copper core is fixed simultaneously, described copper pipe inwall is provided with fireprotection layer.
For the ease of construction, described copper pipe is screw thread copper pipe.
In order to waterproof and anticorrosion, the outer wall of described copper pipe is provided with insulating protective layer.
Owing to have employed technique scheme, the utility model has the advantage that structure is simple, fire protecting performance is good, adopt it not only can improve fireproofing of cable performance, but also reduce difficulty of construction, facilitate operation, the scope of application is larger, when the less position of radius is installed, prevent the damage of copper pipe, reduce potential safety hazard.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is copper pipe structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these execution modes; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of fireproof cable, comprises 1 ~ 5 copper core 1, and be outside equipped with fire prevention mica layer 2 at described every root copper core 1, described 1 ~ 5 copper core 1 is arranged in copper pipe 3, between described copper core 1 and fire prevention mica layer 2, be provided with the belt A4 that prevents fires.
In the utility model, by the setting of fire prevention belt A4, improve fireproofing of cable performance.
Further, fire prevention belt B5 is outside equipped with on 2 layers, described fire prevention mica.Fire prevention belt B5 is set, not only can improves fireproof performance further, but also serve the effect of insulation, protection is played to fire prevention mica layer 2.
Further, described copper pipe 3 inwall is provided with fireprotection layer 6.By fireprotection layer 6 not still to the reinforcement of fireproofing function, also play the effect of fixed copper core 1 simultaneously, prevent from offseting between copper core 1, fixing roundness.
Further, as shown in Figure 2, described copper pipe 3 is screw thread copper pipe.The setting of screw thread copper pipe, not only makes bending radius scope increase, reduces difficulty of construction, but also make Stability Analysis of Structures, and resistance to mechanical performance is strong, and has explosion-proof effect.
Further, the outer wall of described copper pipe 3 is provided with insulating protective layer 7.By the setting of insulating protective layer 7, not only waterproof, corrosion-resistant effect are served to copper pipe 3, but also prevent the oxidation of copper pipe, extend useful life.
Claims (5)
1. a fireproof cable, comprise 1 ~ 5 copper core (1), fire prevention mica layer (2) is outside equipped with described every root copper core (1), described 1 ~ 5 copper core (1) is arranged in copper pipe (3), it is characterized in that: between described copper core (1) and fire prevention mica layer (2), be provided with the belt A(4 that prevents fires).
2. fireproof cable as claimed in claim 1, is characterized in that: be outside equipped with fire prevention belt B(5 at described fire prevention mica (2) layer).
