Abstract
The invention discloses an anti-interference inverter cable which comprises four pairs of main cable cores. Each main cable core is composed of two wires which are insulated from each other and are twisted. A first shielding lapping layer is arranged outside each main cable core, a water blocking layer is arranged outside each first shielding lapping layer, a ground wire core is arranged between every two pairs of adjacent main cable cores, and ground wire cores are arranged at the center positions of the four pairs of main cable cores to form five ground cable cores. Flame retardant layers, second shielding layers and outer sheath layers are sequentially arranged outside the main cable cores and the ground cable cores. According to the above mode, the anti-interference inverter cable is reasonable in structure, strong in shielding performance, and capable of effectively lightening the influence of higher harmonics.
Description
Technical field
The present invention relates to the cable technology field, particularly relate to a kind of anti-interference converter cable.
Background technology
Along with improving constantly of industrial automatization, frequency converter has obtained application very widely.Frequency converter can provide according to the actual needs of motor its needed supply voltage, and then reaches purpose energy-conservation, speed governing.It is more serious that existing converter cable is subject to the interference of high order harmonic component, and shield effectiveness is undesirable.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of anti-interference converter cable, and rational in infrastructure, shielding properties is strong, effectively alleviates the impact of high order harmonic component.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of anti-interference converter cable is provided, comprise: four pairs of master cores, described master core is twisted together by the wire of two mutually insulateds, described master core outer setting has the first shielding lapping layer, the outer setting of described the first shielding lapping layer has water blocking layer, between every adjacent two pairs of master cores and the centre of four pairs of master cores is provided with a ground core, form five ground cores, the outside of described master core and ground core is disposed with flame-retardant layer, secondary shielding layer and external sheath layer.
In a preferred embodiment of the present invention, described the first shielding lapping layer is the copper strips lapping layer.
In a preferred embodiment of the present invention, described secondary shielding layer is the aluminium strip lapping layer.
In a preferred embodiment of the present invention, described external sheath layer is pvc sheath.
The invention has the beneficial effects as follows: the anti-interference converter cable of the present invention, rational in infrastructure, shielding properties is strong, effectively alleviates the impact of high order harmonic component.

In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of anti-interference converter cable one preferred embodiment of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, master core, the 2, first shielding lapping layer, 3, water blocking layer, 4, core, 5, flame-retardant layer, 6, the secondary shielding layer, 7, external sheath layer.
Embodiment
Below will the technical scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of anti-interference converter cable, comprise: four pairs of master cores 1, described master core 1 is twisted together by the wire of two mutually insulateds, described master core 1 outer setting has the first shielding lapping layer 2, the outer setting of described the first shielding lapping layer 2 has water blocking layer 3, between every adjacent two pairs of master cores 1 and centre of four pairs of master cores 1 is provided with a ground core 4, form five ground cores 4, the outside of described master core 1 and ground core 4 is disposed with flame-retardant layer 5, secondary shielding layer 6 and external sheath layer 7.
The serviceability of the anti-interference converter cable of the present invention is good, shielding strong anti-interference performance, the impact that can effectively alleviate high order harmonic component.
Described the first shielding lapping layer 2 is the copper strips lapping layer.
Described secondary shielding layer 6 is the aluminium strip lapping layer.
Described flame-retardant layer 5 is the fire resistance fibre packed layer.
Described external sheath layer 7 is pvc sheath.
The anti-interference converter cable of the present invention, rational in infrastructure, shielding properties is strong, effectively alleviates the impact of high order harmonic component.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
