Abstract
The invention discloses a reinforced anti-extrusion variable frequency cable, which comprises a cable core, wherein the cable core is formed by symmetrically arranging and stranding three main wire cores with large sections and three neutral wire cores with small sections; a gap of the cable core is filled with a filler; a lining layer extrudes and wraps the outside of the cable core; a master shielding layer extrudes and wraps the outside of the lining layer; a sheath extrudes and wraps the outmost layer; each main wire core comprises a main conductor, a separate shielding layer and an anti-extrusion layer; each separate shielding layer extrudes and wraps the outside of each conductor; each neutral wire core comprises a neutral conductor, a separate shielding layer and an anti-extrusion layer; each separate shielding layer extrudes and wraps the outside of the corresponding neutral conductor; a group of reinforcing cores is arranged in the centre of each main conductor; and one reinforcing core is arranged in the centre of each neutral conductor. According to the reinforced anti-extrusion variable frequency cable, the condition that the cable has excellent antistatic coupling capability and anti-electromagnetic induction capability in a use procedure is guaranteed; and the service life of the cable is significantly prolonged, so that the safety and the reliability of the cable are significantly improved; meanwhile, the cost for frequently replacing the cable by users is reduced; and the cable has good social and economical benefits.
Description
Technical field
The invention belongs to power cable field, be specifically related to a kind of reinforced anti-extrusion frequency-changing cable.
Background technology
Domestic and international variable-frequency control technique comparative maturity at present, but the stube cable between variable-frequency motor and variable frequency power supply does not but obtain enough attention.Usually general four-core copper mesh shielded power cable was adopted in the past, this cable is by the less neutral core stranding core of the larger master core in three cross sections and a cross section, between master core and and neutral core between fill filler, then stranding wrapping and copper mesh shielding after extrude sheath.The in use antistatic coupling of this cable and anti-electromagnetic induction ability poor, cable is had puncture hidden danger within a short period of time and the problem such as useful life is shorter; In addition, also there is the problem that cable easily suffers to extrude disconnected core.
Summary of the invention
The object of this invention is to provide one and possess that steadiness is good, superior barrier performance, antistatic coupling, electromagnetic induction, electric wave and power line conducted interference can be reached, prevent the reinforced frequency-changing cable of disconnected core.
The reinforced anti-extrusion frequency-changing cable of one of the present invention, comprises cable core, and this cable core forms by the little neutral core symmetric arrays of the large master core in three cross sections and three cross sections is stranded; The gap of cable core is filled with filling supporter, extrudes inner covering outside cable core, and extrude total screen outside inner covering, outermost layer extrudes sheath; Described master core by leading body, be extruded in sub-shield outside conductor and anti-extrusion layer is formed; Described neutral core by neutral conductor, be extruded in sub-shield outside neutral conductor and anti-extrusion layer is formed; Intracardiacly in leading body be provided with one group of strengthening core, intracardiacly in neutral conductor be provided with a strengthening core.
Further improvement, the thickness proportion between described inner covering, total screen and sheath three is 1:2:1.
Further improvement, described sub-shield adopts aluminium foil, metal wire knitted, metal tape is wrapped combines.
Further improvement, described total screen adopts the shielding construction identical with sub-shield or adopts copper strips embossing, aluminum alloy strip embossing tubular type shielding construction.
Beneficial effect of the present invention is:
Structure of the present invention and the design of material have ensured that cable in use possesses the antistatic of excellence and is coupled and anti-electromagnetic induction ability, the useful life of cable is significantly improved, thus significantly improve the security reliability of cable, decrease user simultaneously and frequently change cable and the expense occurred, there is good social and economic benefits; In addition, not only in conductor, devise strengthening core, also devise anti-extrusion layer outside, make the core not frangibility in cable, the performance of cable is improved greatly; The thickness of the inner covering of cable, always screen and sheath three is by strict required thickness Proportionality design, and make the overall tightness of cable, compactedness is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the reinforced Special cable for frequency converter of one of the present invention, comprises cable core, and this cable core forms by the little neutral core symmetric arrays of the large master core in three cross sections and three cross sections is stranded; The gap of cable core is filled with filler 4, extrudes inner covering 7 outside cable core, and extrude total screen 8 outside inner covering 7, outermost layer extrudes sheath 9; Described master core by leading body 1, be extruded in sub-shield 2 outside leading body 1 and anti-extrusion layer 3 is formed; Described neutral core by neutral conductor 5, be extruded in sub-shield 2 outside neutral conductor 5 and anti-extrusion layer 3 is formed; Intracardiacly in leading body 1 be provided with one group of strengthening core 6, intracardiacly in neutral conductor 5 be provided with a strengthening core 6.
Thickness proportion between described inner covering, total screen and sheath three is 1:2:1, and wherein the thickness of inner covering is 0.5-1.5mm.
Described sub-shield 2 adopts that aluminium foil, metal wire knitted, metal tape are wrapped to be combined.
Described total screen 8 adopts the shielding construction identical with sub-shield or adopts copper strips embossing, aluminum alloy strip embossing tubular type shielding construction.
The invention provides a kind of reinforced anti-extrusion frequency-changing cable; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
