Abstract
The utility model belongs to an improvement of user correspondence line structure, in particular to a self-supporting copper-core twisted user correspondence line. Two copper wires respectively wrapped with an insulating layer are mutually and evenly twisted to be a twisted wire pair. The lateral section of the insulating casing is 8-glyph hole. One 8-glyph hole casing of the insulating casing is provided with at least a twisted wire pair and the other one is provided with a steel wire. The utility model is characterized in not only light weight, high tensile strength, but also good balancing degree of the twisted wire to the electric current and the resistance, low conductor DC resistance, relative stability of the electric capacity among conductors and the electromagnetic field and good correspondence transmission performance. The product is consistent with the good transmission performance of the correspondence cable and overcomes inherent shortcomings of traditional user correspondence line. The correspondence transmission performance surpasses the traditional product and as the good substitution product of the modern user correspondence line.
Description
Technical field
The utility model belongs to the improvement of telex network line structure, particularly self-bearing type copper core pair twist telex network line.
Background technology
At present, the telex network line adopts iron core telephone wire or copper covered steel telephone wire mostly, wherein because the factor of raw material cost, on the market with iron core telephone wire (in addition market also is flooded with the false copper covered steel product of a large amount of copper sulphate immersion plating) in the majority, these two kinds of products are not because of still having country and industry standard, so most of enterprises are all with company standard constraint product quality, and most enterprise product standards are determined examination and test of products project to this series products is many with intensity, and essentially no resistance and line are to Interventions Requested such as resistance balances.So this series products has the high advantage of intensity, but also its weight is big, fault is many, resistance unbalance because of the constraint of its conductor material causes, shortcomings such as attenuation is big can not be consistent with the telecommunication cable conductor, and are former mainly based on can be satisfied substantially in the transmission of voice signal.Along with the progress and the development of society, voice signal no longer is unique transmission signals in the middle of the communications in the message transmission at present, and the past, traditional order wire can not satisfy existing signal transmission quality requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of self-bearing type copper core pair twist telex network line, and is not only in light weight, tensile strength height, and line is good to the current resistor degree of balance, and conductor DC resistance is little, and electric capacity between conductor, electromagnetic field are relatively stable, and the communications performance is good.
The purpose of this utility model is achieved in that a kind of self-bearing type copper core pair twist telex network line, two copper cash that are coated with insulating barrier respectively evenly are twisted into one group of twisted wire pair mutually, cross section is in the borehole jack of its figure of eight of insulating sleeve in figure of eight hole at least one group of twisted wire pair to be set, and in its another borehole jack steel wire is being set.
Because insulating sleeve is coated on twisted wire pair and the steel wire continuously, equably, steel wire has good tensile strength and has certain pliability, so the utility model order wire has been inherited the advantage that traditional product has good tensile strength.In another borehole jack of the figure of eight of insulating sleeve twisted wire pair is being set, twisted wire pair is stranded equably the forming of copper cash that is coated with insulating barrier respectively by two.Twisted wire pair can keep adjacent structure stable between conductor, and the twisted wire pair current resistor degree of balance is good, and conductor DC resistance is little, thereby makes electric capacity, electromagnetic field between conductor relatively stable, has improved the communications performance.
Product multiparity product quality testing department of the present utility model detects, and testing result is seen attached list.
