Abstract
The invention relates to a field or field fight telephone line which is characterized in that: the telephone line comprises an insulating material wrapping layer, two strands of yarn core copper stranded wire cores, which are arranged in the wrapping layer side by side and steel wires symmetrically arranged at two sides of each strand of yarn core copper stranded wire core. As the yarn core in the yarn core copper stranded wire is aramid fiber yarn which has high intensity and good softness, in the process, the yarn core is easy to be stranded with untinned plating copper wires, and four copper conductors in the prior art are changed into six, compared with the prior art, the tin-plating production procedures are not only omitted, but also the purposes that the process is simplified and the manufacturing cost is reduced; in addition, the purposes that the transmission capacity is increased under the same cross-section condition, the transmission quality of the signal is improved and the transmission capacity is increased. Furthermore, the steel wire is directly embedded in the insulating layer of the telephone line for enhancement, the tensile strength is not only improved and the interference to signal transmission is reduced.
Description
Technical field
The present invention relates to a kind of telephone wire, relate to a kind of have tensile strength height, conversation field capacious or field telephone wire specifically.
Background technology
Traditional field (or field operations) telephone wire, employing be three steel, four bronze medal stranded conductors because the intensity of steel wire is very high and copper cash when stranded, be difficult to control on the technology.In addition, because employed copper cash must be a tinned wird, this has also just caused the complicated of its production technology.Moreover, owing to due to the structure of the telephone wire of above-mentioned prior art, also make its transmission signals, transmission capacity and antijamming capability be subjected to certain restriction.
Summary of the invention
That purpose of the present invention provides a kind of production technology to be easy to control just at the existing weak point of above-mentioned prior art, relative cost is lower and can improve signal transmission quality, increase transmission capacity, and field or field telephone wire that its tensile strength is further improved.
Purpose of the present invention can realize by following technique measures:
Field of the present invention or field telephone wire comprise the wrapped with insulation layer, are arranged side by side two strands of yarn core copper stranded conductor cores in integument and are symmetricly set on the steel wire of per share yarn core copper stranded conductor core both sides.
The cross section of telephone wire of the present invention is figure-8 structure, described two strands of yarn core copper stranded conductor cores lay respectively at the position, two centers of circle that constitutes 8 font cross sections, are symmetricly set on the long axis direction arranged of the steel wire of per share yarn core copper stranded conductor core both sides along 8 font cross sections.
The copper stranded conductor of yarn core described in the present invention core is by the stranded conductor that spins the synthetic fibre yarn core and form around the six roots of sensation copper cash that spins the setting of synthetic fibre yarn core; Described steel wire is a zinc-coated wire.
Beneficial effect of the present invention is as follows:
Because to be intensity height, flexibility good spins the synthetic fibre yarn for the yarn core in the yarn core copper stranded conductor conductor of the present invention, therefore, on technology, be easy to twist together with non-tinned wird, and the copper conductor that is used for transmission signals becomes the six roots of sensation by four of prior art, this just makes the present invention not only can save zinc-plated production process compared to existing technology, reach the purpose of simplifying technology, reducing manufacturing cost, also can be implemented in transmission capacity is increased, signal transmission quality is improved, and transmission capacity is increased.
The present invention has adopted the frame mode that will rise in the insulating barrier that four high-strength galvanized steel wires strengthening usefulness also directly are inlaid in telephone wire in addition, and this just not only can make the tensile strength of telephone wire be improved, and has also reduced the interference to the signal transmission simultaneously.
Description of drawings
Accompanying drawing is structural representation of the present invention (a cross section cut-away view).
Embodiment
The present invention is further described below with reference to embodiment (accompanying drawing), but does not limit the present invention.
As shown in the figure, field of the present invention or field telephone wire comprise wrapped with insulation layer 4, are arranged side by side two strands of yarn core copper stranded conductor cores in integument and are symmetricly set on the zinc-coated wire 3 of per share yarn core copper stranded conductor core both sides; Specifically the cross section of telephone wire of the present invention is figure-8 structure, described two strands of yarn core copper stranded conductor cores lay respectively at the position, two centers of circle that constitutes 8 font cross sections, are symmetricly set on the long axis direction arranged of the steel wire of per share yarn core copper stranded conductor core both sides along 8 font cross sections; Described yarn core copper stranded conductor core is by the stranded conductor that spins synthetic fibre yarn core 2 and form around the six roots of sensation copper cash 1 that spins the setting of synthetic fibre yarn core.
The structure of the described yarn core copper stranded conductor core among the present invention can adopt following embodiment to realize: radical/single line nominal diameter: synthetic fibre skein line is spun in 6/0.28 copper cash+1/0.28; 6/0.3 synthetic fibre skein line is spun in copper cash+1/0.3; 6/0.37 synthetic fibre skein line is spun in copper cash+1/0.37; 6/0.43 synthetic fibre skein line is spun in copper cash+1/0.43; 6/0.52 synthetic fibre skein line is spun in copper cash+1/0.52.The specification of the high-strength galvanized steel wire of reinforcement usefulness is consistent with corresponding copper wire diameter.Insulating barrier can adopt cross-linked polyethylene insulating material, insulating material of polyethylene, low-smoke halogen-free polyolefin material.The insulation thickness of its each specification and telephone wire size are shown in Table 1.
