Abstract
The utility model discloses a control cable for an investment. The control cable comprises a cable core; the cable core comprises a plurality of cable conductors which are annularly arranged and are provided with insulating layers wrapped outside; the plurality of cable conductors with the insulating layer wrapped outside are twisted to each other; a wrapping tape layer, a shielding layer and a protecting sleeve layer are sequentially arranged on the twisted cable conductors from inside to outside in a wrapping way; a plurality of radiating holes with triangular sections are formed on the insulating layer and the protecting sleeve layer; circular hollowed filling tubes are filled in the radiating holes; and a plurality of current guiding wires are arranged inside the shielding layer. The control cable for the investment disclosed by the utility model is safe, reliable, high in interference resistance, and high in resistance to high temperature; the firmness of the cable can be ensured under the maximum weight by utilizing the filling tubes in the radiating holes; and the safety of the control cable can be improved by virtue of the added current guiding lines.
Description
Technical field
The utility model relates generally to technical field, relates in particular to a kind of instrument control cables.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes in the world first electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.China's economic growth continuously and healthily, for cable products provides the huge market space, the temptation that Chinese market is strong is so that the world all focuses on Chinese market to sight, reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry allows the world regard with special esteem.Along with the continuous expansion of the industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
The application of electronic computer, instrument and meter is day by day universal, and people's awareness of safety constantly strengthens, and performance and the environmental requirement of the cable supporting with it also improved constantly.Existing computer and instrument are high temperature resistant not high with fire resistance with cable, and the security reliability of cable is low under fire condition, and shielding properties and interference free performance are not high, are not suitable for use in densely populated and higher to device security reliability requirement place.
Therefore, be badly in need of a kind of high temperature resistant, anti-flammability, shielding, instrument control cables that anti-interference is good, safe.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, and a kind of anti-flammability, instrument control cables that anti-interference is good are provided.
The utility model is achieved through the following technical solutions:
The instrument control cables, include cable core, it is characterized in that: described cable core comprises that the outside of many circular array is enclosed with the cable conductor of insulating barrier, the many cable conductors that are enclosed with insulating barrier are mutually stranded, stranded rear cable conductor is enclosed with belting layer, screen, restrictive coating from inside to outside successively, having a plurality of cross sections on insulating barrier, the restrictive coating is leg-of-mutton louvre, is filled with the filling pipe of circular hollow in the louvre, and the screen inboard is provided with several drainage threads.
Described screen adopts proof copper-wire braided to form.
What described cable conductor adopted is bare copper wire.
The material of described filling pipe is polyvinyl chloride.
The utility model has the advantages that:
The utility model is safe and reliable, strong interference immunity, high temperature resistant, and the filling pipe in the louvre is so that the utility model increases the weight of to have guaranteed in the situation of cable weight the fastness of cable in minimum, and the drainage thread of setting up has been strengthened fail safe of the present utility model.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the instrument control cables, include cable core, cable core comprises that the outside of many circular array is enclosed with the cable conductor 1 of insulating barrier 2, the many cable conductors 1 that are enclosed with insulating barrier 2 are mutually stranded, and stranded rear cable conductor 1 is enclosed with belting layer 3, screen 4, restrictive coating 5 from inside to outside successively, and having a plurality of cross sections on insulating barrier 2, the restrictive coating 5 is leg-of-mutton louvre 6, be filled with the filling pipe 7 of circular hollow in the louvre 6, screen 4 inboards are provided with several drainage threads 8.
Screen 4 adopts proof copper-wire braided to form.
What cable conductor 1 adopted is bare copper wire.
The material of filling pipe 7 is polyvinyl chloride.
Claims (4)
1. instrument control cables, include cable core, it is characterized in that: described cable core comprises that the outside of many circular array is enclosed with the cable conductor of insulating barrier, the many cable conductors that are enclosed with insulating barrier are mutually stranded, stranded rear cable conductor is enclosed with belting layer, screen, restrictive coating from inside to outside successively, having a plurality of cross sections on insulating barrier, the restrictive coating is leg-of-mutton louvre, is filled with the filling pipe of circular hollow in the louvre, and the screen inboard is provided with several drainage threads.
