Abstract
The utility model discloses a kind of electric instrument control system oil resistant comprehensive cables, it includes one or more electric power cores, there is filling between the electric power core, the electric power core is coated with band, it is inner sheath outside the band, multiple instrument control conductors are surrounded with outside the inner sheath with one heart, oversheath is congested with outside the instrument control conductor；The comprehensive cable of the utility model can greatly reduce cost, increase laying installation efficiency, and there are also good oil resistant characteristics.
Description
Technical field
The utility model relates to a kind of cable, specifically a kind of electric instrument control oil resistant comprehensive cable.
Background technique
Power cable is the cable for being used for transmission and distributing electric energy, as shown in Figure 1, it is followed successively by electric power core from inside to outside
1, band 3 and oversheath 4 have filling 2 between electric power core 1.Power cable in electric system backbone transmitting and
Distribute high-power power.Instrumentation control cable is used to that electric energy to be transmitted directly to various electrical equipments from the distributor point of electric system
The electric power connection line road of utensil, as shown in Fig. 2, it is followed successively by instrument control conductor 5, band 6 and oversheath 7 from inside to outside,
Signal transmission and control route suitable for instrument, instrument and other electrical equipments.Power cable and instrumentation control cable
Difference:
1, function is different: power cable is in electric system backbone to transmit and distribute big function electric energy: control electricity
Cable is used for the control link of electrical equipment utensil.
2, classification is different: the second class that power cable belongs in five major class of cable: control cable belongs in five major class of cable
Third class (appliance equipment cable).
3, standard is different: the standard of power cable is GB12706；And the standard for controlling cable is 9330.
4, voltage class is different: the voltage rating of power cable is generally 0.6/1kV or more: control cable is mainly
450/750V。
5, structure is different: the power cable and control cable of specification of the same race is in production, the insulation of power cable and sheath
Thickness is thicker than control cable.
6, the mark of insulation core wire is different: the insulation of power cable generally uses color split-phase: controlling the insulated wire of cable
The color of core is typically all monochromatic print digital number.
7, section range is different: power cable is mainly to transmit electric power, typically big section (up to a hundred, thousand squares)；
The section of control cable does not all exceed 10 squares generally.
8, cable core number range is different: power cable is at most generally 5 cores according to grid requirements, and controls cable transmission
It controls signal to use, core number is more, has 61 cores according to most for standard.
It is based on above-mentioned difference, in actual application, power cable and instrumentation control cable are to separate in production
Production, it is installed separately when in use.In different use occasions, there is no problem for independent production, installation.But one
When not only needing power cable a bit, but also needing the occasion of instrumentation control cable, it is separately manufactured and install will cause it is very big at
This waste, and be not easy to install.
Moreover, existing cable product oil resistant characteristic is weak, and there is a large amount of oil in installation environment, so needing cable resistance to
Oiliness is good, in the market most cable all not no characteristics of oil resistant, causes cable to encounter oil and is easy cracking, aging accelerates.
Utility model content
Electric instrument control system oil resistant that is small the purpose of the utility model is to provide a kind of cost and being easily installed is comprehensive
Close cable.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of electric instrument control system oil resistant comprehensive cable comprising one or more electric power cores, the power line
There is filling, it is inner sheath outside the band that the electric power core, which is coated with band, the outer concentric ring of the inner sheath between core
Multiple instrument control conductors are wound with, oversheath is congested with outside the instrument control conductor.
In order to improve the oil resistant characteristic of cable, the material of the oversheath is oil resisting material.
The comprehensive cable of the utility model can greatly reduce cost, increase laying installation efficiency, and it is special that there are also good oil resistants
Property.Two distinct types of product is combined together by the comprehensive cable of the utility model, a kind of two kinds of purposes of product, and economy is non-
Chang Mingxian.The comprehensive cable of the utility model solves mounting and installation difficult problem, can install simultaneously, save the set-up time, mention
High installation effectiveness.The comprehensive cable sheath of the utility model uses the material of oil resistant, improves the oil resistant characteristic of cable.
Detailed description of the invention
Fig. 1 is power cable structure schematic diagram in the prior art.
Fig. 2 is instrumentation control cable structural schematic diagram in the prior art.
Fig. 3 is the structural schematic diagram of the utility model.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
A kind of electric instrument control system oil resistant comprehensive cable, as shown in Figure 3 comprising one or more electric power cores 8,
There is filling 9, it is inner sheath outside the band 10 that the electric power core 8, which is coated with band 10, between the electric power core 8
11, the inner sheath 11 is wound with multiple instrument control conductors 12 with one heart outside, is congested with oversheath 13 outside the instrument control conductor 12.
Production technology:
1, after electric power core 8 produces, stranding is carried out to electric power core 8, is filled in cabling process and fills 9, finally used
Stranding band 10 is by cable core around wrapping, it is ensured that cable core rounding.
2, one layer of inner sheath 11 is squeezed out outside the cable core of power cable 8.
3, with one heart around instrument control conductor 12 outside inner sheath 11.
4, oversheath 13 is squeezed out, is played a protective role.Oversheath 13 using oil resistant material, such as NBR butyronitrile mixed rubber,
Cable oil resistivity is good, and it is not easy to crack that cable encounters oil.
Above-described embodiment does not limit the utility model in any way, all by the way of equivalent substitution or equivalent transformation
The technical solution of acquisition is all fallen in the protection scope of the utility model.
Claims (2)
