The utility model discloses a do not have steamed flame retarded cable, adopt ceramic powder layer, metal spiral restrictive coating and do not have the flame retarding construction that steamed layer combined together, still increased the barrier layer, further improved the flame retardant efficiency who does not have steamed cable.
Description
Technical field
This utility model relates to a kind of halogen-free flame-retardant cable installed for open-wire line.
Background technology
Generally, flame retardant cable on the market, adds the halogenide containing halogen and metal-oxide in its sheath material, evaluates from fire-retardant angle, this is fabulous method, but, owing to these materials containing halogenide, discharge substantial amounts of smog and hydrogen halide when burning, so, low visibility during fire, safe escape and fire-fighting to personnel bring the biggest obstruction, and people dies of asphyxiation for toxic gas the most more.Additionally, after hydrogen halide once reacts with the water in air, i.e. generate " halogenation hydracid ", heavy corrosion instrument and equipment, building cause " secondary disaster ".
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of for open-wire line install halogen-free flame-retardant cable, it can with the flame-retarding characteristic of cable, and nontoxic smokelessly.
For solving above-mentioned technical problem, a kind of technical solution for the halogen-free flame-retardant cable of open-wire line installation of this utility model is:
Including conductor and the insulating barrier being wrapped in conductor outer layer, being sequentially provided with ceramics last layer, metal spiral restrictive coating and Halogen layer from inside to outside at insulating barrier outer surface, the side of described Halogen layer is provided with fixing seat, and fixing seat is for being fixed on wall by cable；Integrally be embedded with barrier layer in the centre of Halogen layer, the inside on described barrier layer is cavity, is perfused with carbon dioxide in cavity；Described barrier layer is extended two catch, and said two catch is in the lower section of Halogen layer, in extending out type.
Distance between the two ends of said two catch is more than or equal to the width of Halogen layer.
Described fixing seat includes the fixing bar that removably connects with Halogen layer and fixed plate integrated with fixing bar, one end that described fixing bar is connected with Halogen layer is square, it is provided with triangle fixture block in square two sides, it is provided with spring between triangle fixture block and fixing bar, is provided with in Halogen layer and the draw-in groove of triangle card Block-matching.
What this utility model can reach has the technical effect that
Compared with prior art, the halogen-free flame-retardant cable installed for open-wire line of the present utility model, directly connect up at wall surface, by fixing seat by cable fixed and arranged on wall, the flame retarding construction using Halogen layer, barrier layer and metal spiral restrictive coating to combine, improves the fire retardant effect of cable further.
Accompanying drawing explanation
Fig. 1 is the sectional view of the halogen-free flame-retardant cable that this utility model is installed for open-wire line.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
Refer to Fig. 1, this utility model provides a kind of halogen-free flame-retardant cable installed for open-wire line, including conductor 1 and the insulating barrier 2 being wrapped in conductor 1 outer layer, ceramics last layer 3, metal spiral restrictive coating 4 and Halogen layer 5 it is sequentially provided with from inside to outside at insulating barrier 2 outer surface, the side of described Halogen layer 5 is provided with fixing seat 6, and fixing seat 6 is for being fixed on wall by cable；Integrally be embedded with barrier layer 7 in the centre of Halogen layer 5, the inside on described barrier layer 7 is cavity, is perfused with carbon dioxide in cavity；Described barrier layer 7 is extended two catch 8, and said two catch 8 is in the lower section of Halogen layer 5, in extending out type.
Distance between the two ends of said two catch 8 is more than or equal to the width of Halogen layer 5.
Described fixing seat 6 include the fixing bar 9 that removably connects with Halogen layer 5 and with the fixing integrated fixed plate of bar 9 10, one end that described fixing bar 9 is connected with Halogen layer 5 is square, it is provided with triangle fixture block 11 in square two sides, it is provided with spring 12 between triangle fixture block 11 and fixing bar 9, in Halogen layer 5, is provided with the draw-in groove mated with triangle fixture block 11.
The halogen-free flame-retardant cable installed for open-wire line of the present utility model, by fixing seat 6, cable is arranged on wall, fixing splicing construction between seat 6 and cable, uses triangle fixture block 11 to realize with the interface arrangment of draw-in groove, and triangle fixture block 11 can realize stretching in fixing bar 9 by spring 12；The material on barrier layer 7 is typically to meet the crackly material of naked light, when fire occurs, the intensity of a fire is usually and up alters, so, first flare can burn in the lower section of cable, and two catch 8 on barrier layer 7 can play stop flare, simultaneously, barrier layer 7 is met fire and is ruptured, and carbon dioxide sprays, and stops fire spreading；It addition, Halogen layer 5 well serves flame retardant effect, and do not produce toxic smog；Even if Halogen layer 5 is destroyed, its internal metal spiral restrictive coating 4 well serves fire-retardant effect, also add ceramics last layer 3 simultaneously, further increases fireproof effect.
A kind of halogen-free flame-retardant cable installed for open-wire line provided this utility model embodiment above is described in detail, principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to the technical scheme helping to understand disclosed in this utility model；Simultaneously for one of ordinary skill in the art, according to thought of the present utility model, the most all will change, in sum, this specification content should not be construed as restriction of the present utility model.
