Background technology

Along with economic, social fast development, use the community of network and office building also more and more, the network cable of using also improves gradually.Network cable, i.e. Network Cable network connection, is the medium that is connected to another one network equipment transmission of information from a network equipment, is the basic building block of network.Cable is as the carrier of signal transmission, also in continuous renewal, to meet the demand of transmission.Under normal conditions, a typical local area network (LAN) is generally can not carry out interconnection network equipment with multiple different types of netting twine.In catenet or wide area network for dissimilar network is linked together and will use different types of netting twine.In the netting twine of numerous kinds, specifically use any netting twine will be according to topology of networks, network configuration standard and transmission speed are selected.At present data network cable can with communication media mainly contain Four types: unshielded twisted pair, Shielded Twisted Pair, coaxial cable and optical cable; Bad for environmental condition, in the situations such as low temperature, greasy dirt, acid and alkali corrosion, often there is the phenomenons such as cold cracking, high temperature deformation, signal transmission are fuzzy, rotten, hardening in existing network cable, and because spacing between each cable is very near, there is crosstalk phenomenon, signal bandwidth and speed are affected.

For example; Chinese patent literature discloses a kind of transparent screen wire [application number: 200720127206.6]; comprise transparent insulation cover, internal portioning layer, twisted-pair feeder and protective layer; it is characterized in that: the inside of transparent insulation cover is provided with the plastics internal portioning layer of right-angled intersection shape; netting twine inside is evenly divided into four parts by internal portioning layer; every part is furnished with two twisted-pair feeders, between internal portioning layer and transparent insulation cover, is provided with insulating protective layer.

Although such scheme has solved the problem that prior art exists to a certain extent, still exists design reasonable not, corrosion stability is poor, and transmission performance is undesirable, draws high intensity poor, cannot meet people's user demand.

Summary of the invention

The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, meets the multicore plastic-aluminum network cable of people's user demand.

For achieving the above object, the utility model has adopted following technical proposal: this multicore plastic-aluminum network cable, it is characterized in that, comprise that ten six roots of sensation are respectively equipped with insulating barrier and internal core wire parallel to each other, the peripheral longitudinally annular of ten six roots of sensation internal core wires is coated with PE plastic membranous layer, in described PE plastic membranous layer, be also enclosed with two glass wires that turned to by some glass fibers and an aluminium plating steel line, be coated with plastic-aluminum overcoat at PE plastic membranous layer lateral surface, described plastic-aluminum overcoat comprises aluminium foil layer, both sides, interior outside at aluminium foil layer are compounded with respectively polyethylene layer, the periphery of described plastic-aluminum overcoat is coated with insulating corrosion sheath.

In above-mentioned multicore plastic-aluminum network cable, the polyethylene layer in described insulating corrosion jacket inner wall and aluminium foil layer outside is connected as a single entity.

In above-mentioned multicore plastic-aluminum network cable, described aluminium plating steel line is arranged on center, ten six roots of sensation internal core wires surround in aluminium plating steel line periphery, described glass wire is wound on the cylindrical centred beam of the peripheral formation of ten six roots of sensation internal core wires in the shape of a spiral, and the described longitudinal annular of PE plastic membranous layer is coated on centred beam periphery.

In above-mentioned multicore plastic-aluminum network cable, between described PE plastic membranous layer and plastic-aluminum overcoat, be also provided with longitudinal annular and be coated on the mica tape on PE plastic membranous layer.

In above-mentioned multicore plastic-aluminum network cable, the radial thickness of described insulating corrosion sheath is greater than plastic-aluminum overcoat radial thickness, mica tape radial thickness, PE plastic membranous layer radial thickness and centred beam radius sum.

In above-mentioned multicore plastic-aluminum network cable, described insulating corrosion sheath is made up of polyethylene layer or polytetrafluoroethylmaterial material.

Compared with prior art, the advantage of this multicore plastic-aluminum network cable is: 1, reasonable in design, simple in structure, meet people's user demand.2, draw high intensity good, anti-aggressivity is strong, long service life.3, transporting number strong, good stability.
