Abstract
The utility model provides a six types of two hoisting net lines of shielding, include from inboard cross separating frame, internal conductor, shielding layer, the insulating sheath of coaxial setting in proper order, be provided with earth conductor between internal conductor and the shielding layer, the internal conductor has the anticlockwise transposition of heart yearn of insulating layer to form by the stranded parcel, its material of shielding layer draws for the aluminium foil wheat, insulating sheath is radiation cross -linking PE with its material of insulating layer. The utility model discloses transmission signal is high -speed stable, and is high temperature resistant, fire behavior is stronger, can effectively prevent the intensity of a fire to stretch and basically do not release when burn harmful substance such as chlorine element when the conflagration, and the life of net twine is longer, and the maintenance cost is hanged down, comparatively environmental protection.
Description
Technical field
The utility model is related to communication cable construction applications, in particular to a kind of six type shieldings twisted pair network cable.
Background technology
With the modernization of computer network, high speed, to the standard more and more higher of the netting twine of transmission signal, Ren Menye
Various types of Network cables are developed for different requirements.
Six class netting twines are a kind of multimedia wire rods of the telematic services such as propagation data, speech, are widely used in width
In the broadband access engineerings such as the band local network of users, the quality of its quality is directly connected to the transmission quality of information communication.Six class nets
The parameters of line line intersect the netting twine of old standard and greatly improve, and transmission frequency also extends to 250MHz or higher.Six
Class network line has certain difference with five classes or super Category-5 twisted pair in shape and in structure, not only increases the ten of insulation
Character skeleton, four pairs of lines of twisted-pair feeder are respectively placed in four grooves of crossing skeleton, and the diameter of cable is also thicker.
Six class cables determine a new capability evaluation index, adopt the single naked copper of specification 23AWG for conductor, polyethylene
Family macromolecule material is insulator, and skin material adopts flame retardant type macromolecular material, and color is grey;Twisted-pair feeder meets international rule
The requirement of model (ISO/IEC), electrical characteristic more than the requirement of six classes (Cat.6) international norm, protect by the isolation of cable center cross
Card NEXT performances and reasonable construction bending radius.LSZH:Represent " low smoke and zero halogen ".Low smoke and zero halogen material can meet safety and environmental protection
Require.
Six class netting twines can be used for voice, ISDN(Integrated Service Digital Network) network (ISDN), ATM155Mbps and 622Mbps,
100MbpsTPDDI, Fast Ethernet and gigabit Ethernet;Than five classes and surpass five classes and have transmission range long, loss is little,
The characteristics such as wear-resisting, pressure resistance.
At present general on the market its high temperature resistant of six-type shielding network wire, fire protecting performance are relatively common, and price is higher, such as its
Durability will bring huge maintenance cost if cannot ensureing, it is therefore desirable to research and develop a kind of long service life, dependable performance
Six-type shielding network wire.
Utility model content
In order to solve the above problems, the performance and service life of cable is improved, there is provided a kind of six type shieldings twisted pair network cable.
A kind of six type shielding twisted pair network cables, including the cross distributing frame, inner conductor, the screen that sequentially coaxially arrange from inner side
Layer, insulating sheath are covered, the inner conductor is formed by the heart yearn that multiply is enclosed with insulating barrier is stranded counterclockwise.
Further, it is provided with earth lead between the inner conductor and screen layer.
Further, its material of the screen layer is the drawing of aluminium foil wheat.
Further, its material is cross-linking radiation PE to the insulating sheath with insulating barrier.
Further, its material of the heart yearn is tin-coated copper.
The utility model has the advantage of, rationally distributed, manufacture craft is relatively simple, and production cost control is reasonable, transmission
Signal is stable at a high speed, and high temperature resistant, fire protecting performance are stronger, fire spreading can be effectively prevented in fire and is not discharged substantially when burning
The harmful substances such as chlorine element, effectively extend the service life of netting twine, reduce network operation cost.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work
Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Poor for general cable its insulating barrier high temperature resistant, fire protecting performance, overload capacity is weaker, and service life cannot ensure
Problem, there is provided a kind of six type shieldings twisted pair network cable.
Make purpose, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, carries out clear, complete description, it is clear that described to the technical scheme in the utility model embodiment
Embodiment be a part of embodiment of the present utility model, rather than the embodiment of whole.Based on the enforcement in the utility model
Example, the every other embodiment that those of ordinary skill in the art obtain under the premise of creative work is not made belongs to this
The scope of utility model protection.
As shown in figure 1, a kind of six type shieldings twisted pair network cable, including the cross distributing frame 1 sequentially coaxially arranged from inner side,
Inner conductor 2, screen layer 3, insulating sheath 4, the inner conductor 2 is twisted counterclockwise by the heart yearn 22 that multiply is enclosed with insulating barrier 21
Conjunction is formed, and earth lead 5 is provided between the inner conductor 2 and screen layer 3.
Further, its material of the screen layer 3 is the drawing of aluminium foil wheat.
Further, its material is cross-linking radiation PE to the insulating sheath 4 with insulating barrier 2.
Further, its material of the heart yearn 22 is tin-coated copper.
The utility model has the advantage of, rationally distributed, manufacture craft is relatively simple, and production cost control is reasonable, transmission
Signal is stable at a high speed, and high temperature resistant, fire protecting performance are stronger, fire spreading can be effectively prevented in fire and is not discharged substantially when burning
The harmful substances such as chlorine element, effectively extend the service life of netting twine, reduce network operation cost.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Identification is of the present utility model to be embodied as being confined to these explanations, i.e., all to make impartial change and modification according to the application scope,
