Abstract
The utility model relates to a self-supporting pair-twisted type broadband telephone line. The technical scheme includes that the self-supporting pair-twisted type broadband telephone line comprises a sheath and at least a pair of insulation core wires located inside the sheath and a metal reinforcing line is disposed inside the sheath. The pair of insulation core wires is mutually twisted spirally. The self-supporting pair-twisted type broad band telephone line avoids problems of crosstalk, error codes, fall lines and the like during a transmission process and increases internet speed. The sheath which utilizes a polrvinyl chloride (PVC) sheath has fine laying property, bending resistance, environment property and anti-aging property. The metal material is utilized as a reinforcing part of the insulation pair-twisted line so as to increase tensile strength of the telephone line. Cross section of the telephone line is 8-shaped, thereby bringing convenience for outdoor laying construction.
Description
Technical field
The utility model relates to self-bearing type pair twist molded breadth band telephone wire, comprises sheath, is in a pair of spiral insulated wire cores and a metal line feeder in the sheath.
Background technology
Along with the continuous development of telecommunications, broadband network has become the requisite liaison method and the office tools of communicating by letter with phone, and still along with the progressively development of ADSL, transmission band is progressively widened, and optical fiber and copper stranded conductor will give and deposit in Access Network.Telecom operators are in order to reduce cost of access, obtain enough bandwidth and transmission performance simultaneously, needs according to turn of the market and communication network development, self-bearing type pair twist molded breadth band telephone wire can realize that the ADSL mode inserts, alternative city communication cable and cored parallel telephone wires effectively prevent cross-talk and electromagnetic interference, avoid crosstalking in the transmission course, error code, problem such as go offline.Line impedance and terminal impedance are mated fully, avoid the reflection of transmission signals and the increase of decay, can give at outdoor construction simultaneously.
Summary of the invention
The purpose of this utility model is: for reducing the broadband communication network cost of access, obtain enough transmission bandwidths and performance simultaneously, satisfy the outdoor laid wiring.
The technical solution of the utility model is: self-bearing type pair twist molded breadth band telephone wire, comprise sheath, and be in a pair of spiral insulated wire cores and a metal line feeder in the sheath, the cross section of sheath is 8 fonts.
The utility model has the advantages that:
1, the utlity model has good tension and transmission performance, conductor material adopts the anaerobic copper cash, has good transmission performance.
2, the utility model adopts the HDPE plastics to insulate, and two thoroughly does away with the edge single lines to carry out fine pith stranded then, avoids crosstalking in the transmission course, error code, problem such as go offline.
3, sheath of the present utility model adopts polyvinyl chloride (PVC) sheath, has good performance and resistance to bend(ing) energy, good environmental performance and the ageing resistace of laying, and is suitable for outdoor utility.
4, the utility model adopts the reinforcement of metal material as the insulation twisted pair wire, and cross section is 8 fonts, improves tensile strength of the present utility model and lays to construction and provide convenience.
Description of drawings
Figure one is the schematic diagram of utility model.
Wherein: 1 lead; 2 insulation; 3 reinforcements; 4 sheaths.
Embodiment
Embodiment: as shown in Figure 1, self-bearing type pair twist molded breadth band telephone wire comprises PVC sheath 4, is provided with two stranded leads 1 in the sheath 4, and lead 1 comprises copper free wire, and lead is coated with HDPE insulating barrier 2, vertically is provided with a metal reinforcement 3 in the sheath 1.
The utlity model has good transmission performance and tensile property, conductor material adopts the anaerobic copper cash, has good transmission performance; Adopt the HDPE plastics to insulate, two thoroughly do away with the edge single lines to carry out fine pith stranded then, avoid crosstalking in the transmission course, error code, problem such as go offline; Sheath adopts polyvinyl chloride (PVC) sheath, has good performance and resistance to bend(ing) energy, good environmental performance and the fire resistance of laying; Adopt the reinforcement of metal material, improve tensile strength of the present utility model as the insulation twisted pair wire; Cross section is 8 fonts, lays to construction and provides convenience.
