The utility model has the beneficial effects that a kind of organic fire prevention flexible cable of the utility model, including a plurality of cable core, cladding The glass belt of a plurality of cable core, the low smoke and zero halogen sheath for coating glass belt and fire prevention filler, fire prevention filler is for filling out It fills between cable core and glass belt between adjacent two cable cores, the cable core includes that the twisted copper formed of a plurality of soft copper body is led Body, the polyester layer for coating copper conductor, the two-sided synthetic mica belt for coating polyester layer, for coating two-sided conjunction One kind of Ceramic Composite belt at mica belt and the insulating layer for coating ceramic composite tape layers, the utility model is organic Fireproof flexible cable has heat-resisting, corrosion-resistant, high-intensitive, high flexibility and fireproof performance.
Detailed description of the invention
Utility model is described further using attached drawing, but the embodiment in attached drawing does not constitute and appoints to the utility model What is limited, for those of ordinary skill in the art, without creative efforts, can also be according to the following drawings Obtain other attached drawings.
Fig. 1 is a kind of structural schematic diagram of organic fire prevention flexible cable of the utility model.
Include in figure:
Copper conductor 1, polyester layer 2, two-sided synthetic mica belt 3, Ceramic Composite belt 4, galvanized steel strip armor 5, absolutely Edge layer 6, organic fire prevention filling mud 7, glass belt 8, inner sheath 9, Du Pont silk layer 10, low smoke and zero halogen sheath 11.
Specific embodiment
The utility model is further described with the following Examples.
A kind of organic fire prevention flexible cable of the present embodiment, as described in Figure 1, the glass including a plurality of cable core, a plurality of cable core of cladding Fibre ribbons layer 8, the low smoke and zero halogen sheath 11 for coating glass belt 8 and fire prevention filler, fire prevention filler is for being filled in cable core Between glass belt 8 between adjacent two cable cores, the fire prevention filler is that organic fire prevention fills mud 7, the cable core packet Include the twisted copper conductor 1 formed of a plurality of soft copper body, the polyester layer 2 for coating copper conductor 1, for coating polyester layer 2 Two-sided synthetic mica belt 3, the Ceramic Composite belt 4 for coating two-sided synthetic mica belt 3 and multiple for coating ceramic The insulating layer 6 of crossed belt layer 4.
The organic fire prevention flexible cable of the present embodiment, coats a plurality of cable core using glass fibre belt, glass fibre belt, that is, glass cord, It using the glass fibre of resistance to high-strength, is woven through special process, it is elasticity glass fiber rope made of a kind of innovation weave, is had The main performances such as heat-resisting, corrosion-resistant, high-intensitive.Copper conductor 1 is formed by a plurality of soft copper body is twisted, and the flexibility of cable can be improved, With polyester layer 2 coat copper conductor 1, polyester belt mechanical strength with higher, good insulation preformance, can the property such as high temperature resistant or low temperature Energy.Mica tape has excellent high temperature resistance and flame resistance energy, and harmful vapors are substantially not present when meeting open fire burning Volatilization, synthetic mica tape fluorophlogopite belt are free of the crystallization water, and 1375 DEG C of fusing point, high temperature resistance is best.Outside polyester layer 2 After wrapped 3 layers of two-sided synthetic mica belt, cable core has the advantages that excellent hot-face insulation.In addition, fire-resistant isinglass belt also has Good flexibility, so that cable core also has soft, bending resistance characteristic.
