Abstract
The utility model relates to the cable field, and relates to a copper cladded aluminum signal transmission cable and a manufacturing method thereof. The performance and the cost of the signal cable are better than those of the prior signal cable. The cable structure comprises: 1, copper cladded aluminum; 2, a cable shielding tape; and 3, an aluminum sheath. The manufacturing processes comprising a first step of stranding the copper cladded aluminum; a second step of wrapping the cable shielding tape; and a third step of extruding the aluminum sheath. According to the copper cladded aluminum signal transmission cable, while the adaptability and the flexibility are increased, the size and the weight are reduced. The mechanical strength is better enhanced and the shielding performance is better, and the cable can be used for a trunk route of a railway electrification section and signal transmission in a high voltage interference area.
Description
Technical field
The utility model relates to field of cables, relates to a kind of copper cover aluminum signal power transmission and transformation cable and manufacturing approach thereof, and this signal cable performance cost is superior to existing signal cable.
Background technology
Signal cable mainly is meant the Railway Special signal cable, is applicable to that rated voltage exchanges the control circuit of 500V or direct current 1000V and following transmission railway digital signal, audio signal or automatic signalling.Main model has: railway signal cable, railway combined sheath signal cable, railway digital signal cable, railway inner shield digital signal cable, railway axle-counting signal cable, railway answering machine data transmission cable.The signal of general signal cable transmission is very little; Be interfered for fear of signal; There is one deck screen the signal cable outside, is generally braiding copper mesh or copper pool, and screen needs ground connection; External interference signal can be imported the earth by this layer, avoids interference the loss that signal gets into inner conductor interference the reduction simultaneously transmission signals.The utility model is to be different from the classical signals cable; Adopt the copper cover aluminum twisted wire; The structure of cable shield tape wrap, aluminium sheath, it has when increasing adaptability and flexibility, has reduced volume and weight; More strengthen mechanical strength and good shielding properties, can be used for the main line or the defeated change of forceful electric power mush area signal of railway electrification section.
Summary of the invention
The purpose of the utility model is to existing signal cable product, and a kind of high-performance, volume is little and shield effectiveness is stronger signal cable substitute products are provided.
The utility model comprises the copper cover aluminum that sets gradually from the inside to the outside, cable shield tape wrap, aluminium sheath.Technical process is the copper cover aluminum twisted wire, and the cable shield tape wrap is wrapped, extrude aluminium sheath.
The conductor of the utility model is a copper cover aluminum, and shielding material is the cable shield tape wrap, and sheath material is an aluminium.
The utlity model has following characteristics:
1, copper clad aluminum conductor has unique composite performance, and it possesses the conductivity of copper and the little composite attribute of density of aluminium simultaneously.
2, the cable shield tape wrap has reduced volume and weight when increasing adaptability and flexibility, has more strengthened mechanical strength and good shielding properties.
3, the utility model can be used for the main line or the defeated change of forceful electric power mush area signal of railway electrification section.

Embodiment
With reference to Fig. 1, the utility model copper cover aluminum signal power transmission and transformation cable structure is: 1, copper cover aluminum 2, cable shield tape wrap 3, aluminium sheath.With reference to Fig. 2, its processes process: 1., the copper cover aluminum twisted wire; 2., the cable shield tape wrap is wrapped, its parameter is seen table 1; 3., adopt the continuously extruded friction of aluminium bar to squeeze Manifold technology, the mold system of cable is board-like by original runner lamination, make the core rod of castle formula into; And by the Aided Design of computer; The pressure of aluminium in runner is consistent, has both improved concentricity and the roundness of extruding aluminum pipe, make the thickness of extruding aluminum pipe more even again; In cable core outside and aluminium sheath outside, carry out cable core cooling and aluminum pipe cooling respectively at last.
