Abstract
The utility model discloses a self-supporting paired telecommunication cable, comprising 1 to 5 pairs of conductor core wires with an insulation wrap and a low-carbon steel wire tendon. Both the conductor core wires and the steel wire tendon are provided with an external restrictive coating made of the black polyethylene material and the two restrictive coatings are connected with the cross section in the shape of an ''8''. Each pair of conductor core wires are arranged in twisted pair at the spacing of shorter than 4.5 cm. The utility model is convenient for outdoor construction with long service life. Since the polyethylene material is used as the external restrictive coating, the weather and ageing resistance property is better. The utility model is suitable for broadband network cabling.
Description
One, technical field
The utility model relates to telecommunication cable, is specifically related to a kind of self-bearing type pair twist telecommunication cable.
Two, background technology
Because development of computer network, the broadband has entered family, and telecommunication cable is the bridge that connects huge numbers of families, and therefore, the application of telecommunication cable has entered a unprecedented period of expansion.Present employed telecommunication cable, because core is very thin, own itself do not have bearing capacity, directly lays insufficient strength out of doors, breaks easily, will adopt steel wire to hang usually, assists laying, it is very complicated to construct.On the other hand, weatherability, the ageing resistance of telecommunication cable oversheath also await improving at present.
Three, summary of the invention
The purpose of this utility model is in order to overcome the deficiency of prior art, the self-bearing type pair twist telecommunication cable of a kind of long service life, easy construction to be provided.
The utility model self-bearing type pair twist telecommunication cable, be characterized in: it has the insulating covering conductor core wire by a pair of or five pairs of as many as and a mild steel wire muscle line is formed, described conductor core wire and described steel wire muscle line all are provided with oversheath, and both oversheaths connect as one, its cross section is the figure of eight, described oversheath is made with the black polyethylene material, and described every pair of conductor core wire is according to being provided with less than the long pitch pair twist of 4.5cm.
The advantage of the utility model self-bearing type pair twist telecommunication cable is: the self-bearing type structure, and not only made things convenient for construction, and strengthened the useful life that product is laid out of doors, adopt polythene material to make oversheath, strengthened weatherability and ageing resistance.
The utility model can be used for transfer of data, the transmission frequency broad, and it is little to decay, and transmission performance is better than the voice transfer cable, is applicable to the broadband entrance line.
Four, description of drawings
Described in detail below in conjunction with the utility model embodiment accompanying drawing:
Fig. 1 is the cross section cutaway view of the utility model embodiment;
Fig. 2 is that conductor core wire pair twist described in the utility model is provided with schematic diagram.
Five, embodiment
As shown in Figure 1, the utility model self-bearing type pair twist telecommunication cable, it has insulating covering 2 conductor core wires 1 by two pairs and a mild steel wire muscle line 3 is formed, conductor core wire 1 all is provided with oversheath 4 with steel wire muscle line 3, and both oversheaths connect as one, its cross section is the figure of eight, and oversheath 4 usefulness black polyethylene materials are made.As shown in Figure 2, every pair of conductor core wire 1 is according to being provided with less than the long pitch pair twist of 3.5cm.
