Abstract
Disclosed is a novel flame-retardant cable. The body is a bunched cable internally provided with a plurality of single-core wire cores in bunchy distribution to improve the data transmission capacity, a flame-retardant sheath is wrapped outside the bunched single-core wire cores, and water-blocking filling material is filled between the flame-retardant sheath and the single-core wire cores. The flame-retardant sheath is in a double-layer structure and comprises an outer sheath made of low-smoke halogen-free material and an inner sheath braided with fire-proof fiber filaments. The novel flame-retardant cable is reasonable in structure and convenient in processing and can be used to effectively carry out fire-proof flame-retardant protection on optical cables, thus ensuring the normal operation of relevant communication equipment.
Description
Technical field
The utility model relates to electric power optical cable, is specially a kind of novel flame-retardant optical cable.
Background technology
Along with growing with each passing day of information interchange amount in the fast development of communicating by letter and the people's daily life, the communications industry is also more and more higher for the requirement of transmission cable.Optical cable has obtained promoting widely and using because the singularity of material own has the advantages such as security performance is good, use cost is low, installation is simple, long transmission distance, the compatible amount of information is large, bandwidth is outstanding, volume is little, quality is light.But, in present optical cable is produced, owing to the transmission performance of worry about optical cable security performance is ignored to some extent.Special in the high zones of fire safety grade such as some subways, light rail, tunnel, bridge, park, forest zones, antijamming capability and the anti-flammability of optical cable itself are had higher requirement.
The utility model content
The technical matters that the utility model solves is to provide a kind of novel flame-retardant optical cable, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of novel flame-retardant optical cable, its body is the pencil cable, inside comprises that the many single-core line cores that are the pencil distribution are in order to improve its data transmit-receive ability, the outside of the single core of pencil is enclosed with fire retardant jacket, simultaneously, also be filled with the filling material that blocks water between fire retardant jacket and single-core line core, described fire retardant jacket is the double-decker sheath, comprises that oversheath and fire insulation filament that the low smoke and zero halogen cellulosic material is made weave the inner sheath of making.
In the utility model, for improving the fire retardant performance of cable, outside fire-retardant, put also and can be coated with the last layer refractory coating.
In the utility model, the circular cable core of described cable core internal layer is preferably 8 ~ 12.
Beneficial effect: the utility model adopts nonmetallic materials to make, can be in the situation that do not affect the physical strength that communication quality has effectively strengthened cable core, and simultaneously nonflammable, the destruction that can effectively prevent the naked light cable.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of novel flame-retardant optical cable of Fig. 1, in the present embodiment, comprise cable core 1 and sheath, wherein sheath comprises double-layer structure, be respectively inner sheath 2 and the outer field oversheath 4 of internal layer, block water filling material 3 between inner sheath 2 and cable core 1, and cable core 1 is positioned at inner sheath 2 inboards, comprises 12 independently single-core line cores.
Wherein, inner sheath 2 is made for the braiding of fire insulation filament, and oversheath 4 is made for the low smoke and zero halogen cellulosic material.
Above demonstration and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
