Description
Technical field
The utility model relates to a kind of power transmission cable, particularly relates to a kind of 450/750V and following polyethylene insulation electronic computer control cable.
Prior art
Along with the high speed development of information industry, electronic computer has entered all trades and professions.In recent years, electronic technology was brought in constant renewal in, and was also increasing to the consumption of electronic computer cable.At present, domestic a lot of cable producer has all developed electronic computer cable in succession, but the electronic computer cable electric pressure of Xiao Shouing is low on the market, can only transmit weak electric signal, can't satisfy the needs of power electricity (forceful electric power) and control circuit thereof, need to remedy this defective with other cables, not only constructing operation bothers, circuit cost height, and install that to lay floor space big, cause some hidden danger to safety.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of screening electron computer control cable that can overcome the defective of prior art, it adopts single to transmission along separate routes, add double layer screen, can improve the antijamming capability of cable greatly, take into account the transmission of power supply and control circuit thereof and computer weak electric signal simultaneously.
For achieving the above object, the technical solution of the utility model is: described screening electron computer control cable by several insulated wire cores to forming so that different torques are stranded, wherein the right outside of each insulated wire all is provided with screen, wrapped again polyester belt is fixed outside this screen, each insulated wire between the gap be filled with the non-hygroscopic filler, in this control cable periphery one deck screen is set again, outermost layer then wraps up oversheath.
Computer control cable of the present utility model passes through the improvement in the construction of cable, insulating material and the technological design, realized taking into account simultaneously the transmission of power supply and control circuit and weak electric signal, can transmit the electrical source of power control signal, again can transportation simulator and digital signal.Adopt advanced equipment and technology on the construction of cable, the pair twist pitch is controlled in strictness, has guaranteed the stability of mutual capacitance, adopts double layer screen, has improved the antijamming capability of cable greatly, has reduced the decay and the distortion of signal.This cable can separate single to using, and also can manyly can transmit multichannel heterogeneous networks signal to using simultaneously, has improved the effectiveness of cable, has reduced the wiring that repeats at computer management center.This voltage cable grade height can be the power line below the 450/750V, illuminating line power supply in transmission computer control, pilot signal.It is compared with common plastics insulation control cable with traditional electronic computer signal cable, has fairly obvious advantage:
1, traditional electronic computer signal cable is to design for transmission computer electromagnetic signal specially, the performance purposes is more single, can't satisfy the computer management center of vast capacity and Surveillance center demand, and computer control cable of the present utility model can satisfy the transmission of multichannel number, vast capacity supervisory computer control signal preferably to cable.The difference with both now is compared as follows:
1) computer control cable operating voltage height of the present utility model can satisfy the needs of different occasions and distinct device;
2) thickness of insulating layer of the insulated wire cores of described control cable is bigger, more secure and reliable to use than Computer signal cable thickness;
3) owing to adopt two-layer reinforcement shielding, pair twist divides shielding and set shielding, so this computer control cable antijamming capability is better than the Computer signal cable;
4) computer control cable can transmit light current and forceful electric power signal simultaneously, comprises the power electric signal of 380V.
2, common plastics insulation control cable (cable of GB9330-88 regulation) only is applicable to ac rated voltage 450/750V and occasions such as following control, monitoring loop and protection circuit, and computer control cable of the present utility model mainly is applicable to electrical control and the transmission and the monitoring digital, analog signal at the Computer Processing center of equal voltage registration.
1) structurally, common plastics insulation control cable adopts the single insulated wire cores of multicore, and computer control cable of the present utility model then adopts many to insulated wire cores combination (every pair can be the two wires group, also can be three-way group of band ground protection); And the every pair of core adopts different torques (must strict control), avoided line to cross-talk and mutual interference mutually.
2) on performance; common plastics insulation control cable is mainly used to handle the various electrical control signals under the rated voltage; just seem beyond one's ability if be used for handling various high-frequency signals, decay or phase distortion significantly appear in signal regular meeting, have a strong impact on transmission quality.And computer control cable of the present utility model adds double layer screen again owing to adopted list to transmission along separate routes, has improved the antijamming capability of cable greatly, reduces the decay and the distortion of signal, has solved the problems referred to above well.

Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
See also Fig. 1: be a specific embodiment of the present utility model.This screening electron computer control cable is formed so that different torques are stranded 1 by 3 insulated wire cores, and described insulated wire comprises two conductors 11 and wraps the insulating barrier of tiing up at this conductor 11 outer surfaces 12 respectively 1.Each line is to adopting different torques stranded, is electromagnetic phase mutual interference when reducing line to transmission signals.Wherein each insulated wire all is provided with screen 2 to 1 outside, wrapped again polyester belt 3 is fixed outside this screen 2, gap between each insulated wire is to 1 is filled with non-hygroscopic filler 4, in this control cable periphery one deck screen 5 is set again, and outermost layer then wraps up oversheath 6.
The insulating material of described insulating barrier 2 adopts Halogen plastic polyethylene material, does not conform to polar group, is to occur the molecular polarization phenomenon during for fear of the polar molecule transmitting high-frequency signal.The raw material main body is LDPE, also can add a spot of HDPE.Adverse circumstances such as that if cable need be laid in is high temperature resistant, acid-alkali-corrosive-resistings, insulating barrier also can be selected F46 or F4 material for use.
