Abstract
The utility model provides a twisted pair, comprising a sheath, a shielding layer, a streamline, a tearing rope and a twinning group. The shielding layer is formed by aluminum foil and polyester strip. The lead core in the twinning group is a copper coated aluminum conductor. An olefin insulating layer is coated outside the copper coated aluminum conductor. The beneficial effects of the utility model are that compare with copper, the price of aluminum is much cheaper, and so the copper coated aluminum core conductor can replace the copper core conductor, which makes the cable cost reduce about 30 percent, and at the same time, the price of the cable is reduced. The cable of the utility model saves the copper resources, and achieves super quality and lower cost. The cable can be widely used in the network wiring with the maximum transmission frequency of 100MHZ.
Description
Technical field
The utility model relates to cable, is a kind of horizontal paired cable of 5 classes that surpasses more specifically.
Background technology
At present, wiring between the distributing frame in local area network (LAN) usefulness, the building communication synthesis wiring system between service area communication exit and handing-over, and the telex network exit of dwelling house comprehensive wiring system is to the network layout between the distributing frame, mainly based on the paired cable line, mostly be the network layout that uses as the digital communication of copper core with surpassing the horizontal paired cable of 5 classes, but because holding at high price of present copper makes the cable price higher relatively.
Summary of the invention
The purpose of this utility model provides a kind of above-mentioned defective that overcomes, and can reduce the cable price, and a kind of paired cable used of inexpensive network layout.
The utility model is realized in the following way: a kind of paired cable, mainly by sheath, screen, drain wire, tear the rope and the pair twist group form, it is characterized in that screen is made of aluminium foil and polyester belt; The core of the lead in the pair twist group is a copper clad aluminum conductor.
A kind of paired cable is characterized in that copper clad aluminum conductor is surrounded by polyolefin insulation layer outward.
A kind of horizontal paired cable of 5 classes that surpasses, mainly by sheath, screen, drain wire, tear the rope and the pair twist group form, it is characterized in that screen is made of aluminium foil and polyester belt; The core of the lead in the pair twist group is a copper clad aluminum conductor.
The beneficial effects of the utility model are: because aluminium is with respect to copper, it is cheap many that price is wanted, therefore with copper-covered aluminum-core conductor Alloy instead of Copper core conductor, make cable cost can reduce about 30%, also reduced the cable price simultaneously, and saved the copper resource, accomplished inexpensive, can be widely used in network layout, make telecom operators and the user fund that less input, just can obtain good economic benefit.Its high-transmission frequency is 100MHz.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a cross sectional representation of the present utility model.
Among the figure, 1. sheath, 2. drain wire, 3. aluminium foil, 4. polyester belt, 5. the pair twist group is 6. torn rope, 7. copper clad aluminum conductor, 8. insulating barrier.
Embodiment
Product type specification as shown in Figure 1 is a kind of paired cable of HSAYVP-5E 4 * 2 * 0.5, mainly by sheath (1), screen, drain wire (2), tear rope (6) and four pairs of pair twist groups (5) are formed, screen is made of aluminium foil (3) and polyester belt (4); The core of the lead of (5) is copper clad aluminum conductor (7) in the pair twist group.Copper clad aluminum conductor (7) outside is surrounded by polyolefin insulation layer (8).During manufacturing, the copper cover aluminum bar through wire drawing machine repeatedly drawing, is pulled into copper clad aluminum conductor (7) silk, annealedly again make soft silk conductor, the polyolefin insulation layer (8) of squeezing one deck different colours on conductor with plastic extruder has so just been made insulated wire cores.Two thoroughly do away with the edge core is twisted into a pair of pair twist group (5) with the back twist pairing device, four pairs of such pair twist groups (5) are carried out stranding with cabler again, vertical put one tear rope (6) after, indulge bag one deck polyester belt (4) and aluminium foil (3) mask tape then and indulge and put a soft copper silk drain wire (2), so just made cable core.Squeeze one deck pvc sheath (1) in the cable core outside with plastic extruder at last, cable is just made and has been finished.
Claims (3)
1. paired cable, mainly by sheath, screen, drain wire, tear rope and the pair twist group is formed, it is characterized in that screen is made of aluminium foil and polyester belt; The core of the lead in the pair twist group is a copper clad aluminum conductor.
2. a kind of paired cable as claimed in claim 1 is characterized in that copper clad aluminum conductor is surrounded by polyolefin insulation layer outward.
3. one kind surpasses the horizontal paired cable of 5 classes, mainly by sheath, screen, drain wire, tear the rope and the pair twist group form, it is characterized in that screen is made of aluminium foil and polyester belt; The core of the lead in the pair twist group is a copper clad aluminum conductor.
