Abstract
The utility model relates to a broadband LAN is with fire -resistant data cable relates to cable technical field, including cable core and protective sheath, the protective sheath cladding is in outside the cable core, the protective sheath divide into two -layerly, and two -layer protective sheath is interior protective sheath, outer protective sheath, it separates the fire bed still to be equipped with a metal between interior protective sheath and the outer protective sheath. The utility model discloses fire -resistant data cable is equipped with the fire -retardant fire resisting construction of multilayer, has realized multiple protect function, has improved effectively the utility model discloses the comprehensive fire behavior of data cable.
Description
Technical field
The present invention relates to field of cable technology, be specifically related to a kind of wideband data cable, particularly a kind of broadband LAN fireproof data cable.
Background technology
Common wide data cable adopts the coated overcoat of pvc material to make, and the cable manufacturing process of this structure is simple, with low cost, but cannot meet the demand of a lot of fire-proof and explosion-proof industry of needs.When cable is used for needing in fireproof fire-fighting system, common wide data cable is easy to ignition and produces open flame source, holds fire hazardous.Traditional pvc material can produce the smog containing toxic gases such as hydrogen halides, carbon monoxide, carbon dioxide when burning, this not only affects carrying out smoothly of disaster relief work, and causes secondary disaster to lives and properties.
Summary of the invention
The object of the present invention is to provide a kind of broadband LAN fireproof data cable, solve above technical problem.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of broadband LAN fireproof data cable; comprise cable core and protective sleeve, described protective sleeve is coated on outside described cable core, and described protective sleeve is divided into two-layer; two-layer protective sleeve is internal protective cover, outer jointing jacket, is also provided with a metal refuge floor between described internal protective cover and outer jointing jacket.
Described cable core comprises conductor and is coated on the insulating barrier outside described conductor.
Described protective sleeve comprises the internal layer flame retardant plastic bed of material and outer Ceramic silicon rubber layer.
Described metal refuge floor is that raw material is made with composite steel-plastic belt.
Described cable core comprises eight stranded between two cable cores with the center of protective sleeve for the center of circle twists together.
Beneficial effect of the present invention is: a kind of broadband LAN fireproof data cable, is provided with multi-layer fire-retarded fireproof construction, achieves multiple protection functions, effectively improves the Comprehensive Preventing fire performance of data cable of the present invention.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention will be further described:
Fig. 1 is data cable structural representation of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
With reference to Fig. 1, broadband LAN fireproof data cable, comprise a cable core and a protective sleeve, protective sleeve is coated on outside cable core, the insulating barrier 2 that cable core comprises conductor 1 and is coated on outside conductor 1.Insulating barrier 2 adopts high-density polyethylene insulation material, and high-density polyethylene insulation material dielectric constant is little and stable, ensures that the electric parameter of data cable meets the requirement of transmission performance.
Described protective sleeve comprises two-layer, is respectively the flame retardant plastic bed of material 3 that is arranged on internal layer and is arranged on outer field Ceramic silicon rubber layer 5.It has possessed the good fundamental characteristics of silicon rubber elastic to Ceramic silicon rubber material at normal temperatures, there is nontoxic, tasteless, high-low temperature resistant, resistance to ozone aging, weatherable, excellent electrical insulation capability, also possessed the processing characteristics that common high temperature silicone rubber is good, flexible cable state can have been kept between 40 degrees below zero is to 200 degree.Attack at flame; when temperature reaches more than 300 degree; rigid sponge ceramic body can be converted to by original soft condition; hardening rear fireproof jointing sheath inside produces hole; be conducive to insulation; such sponge ceramic body has significant fire prevention and intercepts the effect of high temperature, thus machinery change and electrical property change do not occur the internal structure of effective protection cable.
Also indulge between the described flame retardant plastic bed of material 3 and described Ceramic silicon rubber layer 5 and be surrounded by one deck composite steel-plastic belt 4.Composite steel-plastic belt both can be used as separator and had isolated two-layer protective sleeve, was isolated in outside the flame retardant plastic bed of material as metal refuge floor by flame, can also play the effect of armouring protection.The described flame retardant plastic bed of material 3 adopts the low smoke and zero halogen restrictive coating be made up of low-smoke halide-free fireproof composite polyolefine material.Traditional polyvinyl chloride plastic bed of material can produce the smog containing toxic gases such as hydrogen halides, carbon monoxide, carbon dioxide when burning, this not only affects carrying out smoothly of disaster relief work, and causes secondary disaster to lives and properties.And after the present invention adopts the low smoke and zero halogen restrictive coating be made up of flame retardant polyolefine material, not only good flame retardation effect, and toxic black smoke can not be produced during burning, realize environmental and durable advantage.Because said structure has good Comprehensive Preventing bad temper, therefore cable can be used in the environment occasions such as the fire-fighting system of fire-proof and explosion-proof requirement.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-mentioned example and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
