Abstract
The utility model discloses a double-layered shielded motor connection cable, and relates to the technical field of cables. The double-layered shielded motor connection cable comprises a cable core which is formed by a plurality of stranded and bundled thin bare copper wire conductors and core insulating layers which are coated onto the outer layers of the copper wire conductors. Grounding protection wires are arranged in gaps between the plurality of copper wire conductors, an outer sheath is arranged on the outside of the cable core, and an aluminium foil shielding layer and a braided shielding layer are arranged between the cable core and the outer sheath successively. According to the utility model, a PE core insulating layer is adopted, so advantages of low operating capacitance and low shielding capacitance are realized, and the power loss is less in the process of transmission compared with conventional PVC cables, so the double-layered shielded motor connection cable is widely used in occasions, such as the occasion in which the cable is connected with a driver, the occasion in which a frequency converter is connected with a motor, the occasion in which high-noise electromagnetic interference exists, etc.
Description
Technical field
The utility model relates to the cable technology field, is specifically related to a kind of double layer screen motor cable jumper.
Background technology
Along with the progress of science and technology and the development of national economy, various advanced persons' instrument and control are constantly released and are used, and quantity is also in continuous increase, and monitoring circuit and protection loop also constantly increase.Simultaneously, the environment of cable installation also becomes increasingly complex, environmental interference and and cable between the phase mutual interference also more and more serious.Traditional control cables, its shielding construction is simple, shield effectiveness is poor, antijamming capability a little less than, in the serious environment of electromagnetic interference, affect transmission quality, cause instrument and circuit occur to use potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of double layer screen motor cable jumper, and it has low mutual capacitance and low mask capacitor, compares with traditional PVC cable, and kinetic equation loss is less during transmission, and its shield effectiveness is better.
In order to solve the existing problem of background technology; the utility model is by the following technical solutions: a kind of double layer screen motor cable jumper; it comprises by multiply and carefully is twisted into bundle thin bare copper wire conductor and be wrapped in the formed cable core of the outer field core insulation layer of copper wire conductor; described stranded copper wire conductor is provided with the ground protection line between the gap; and described cable core is provided with oversheath outward, is provided with successively foil shielding layer and woven shield between cable core and oversheath.
As improvement, described woven shield is copper wire interlacing screen.
As improvement, described core insulation layer is PE core insulation layer.
As improvement, described oversheath is the transparent PVC oversheath.
The utlity model has following beneficial effect: adopt aluminium foil and steel wire double layer screen, its shield effectiveness is good, antijamming capability is strong; Between the cable core gap, be provided with earth connection, avoid occurring short circuit and something unexpected happened has improved safe handling, guaranteed its signal transmission quality, in a word, this stube cable adopts the PE core insulation, has low mutual capacitance and low mask capacitor, compares with traditional PVC cable, kinetic equation loss is less during transmission, be widely used in cable and be in transmission connection, frequency converter is in the same place with motor, the occasions such as high noisy electromagnetic interference.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1; this embodiment is by the following technical solutions: a kind of double layer screen motor cable jumper; it comprises by multiply and carefully is twisted into bundle thin bare copper wire conductor 1 and be wrapped in copper wire conductor 1 outer field core insulation layer 2 formed cable core 4; described stranded copper wire conductor is provided with ground protection line 3 between 1 gap; and be provided with oversheath 7 outside the described cable core 4, between cable core 4 and oversheath 7, be provided with successively foil shielding layer 5 and woven shield 6.
Described woven shield 6 is copper wire interlacing screen.
Described core insulation layer 2 is PE core insulation layer.
Described oversheath 7 is the transparent PVC oversheath.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
