Detailed description of the invention
As shown in Figure 1, a kind of built-in how stranded inner core of the present invention also can reduce the conductor of AC resistance and includes passing into positive direct-current electricity, make himself with the inner wire 10 of positive charge, this inner wire 10 includes multiple inner core 11 and implant 14, the mutual stranded bunchy of the plurality of inner core 11, outer surface one layer of inner insulating layer 12 of cladding of stranded bundles of the plurality of inner core 11, it is filled with this implant 14 between stranded bundles of the plurality of inner core 11 and this inner insulating layer 12, the outer surface of this inner insulating layer 12 is coated with one layer of outer contact 13 for transmitting alternating current, combine closely between this inner insulating layer 12 and this inner wire 10, combine closely between this outer contact 13 and this inner insulating layer 12, this inner wire 10, this inner insulating layer 12, this outer contact 13 concentric (being same axle center), wherein: this inner core 11, this implant 14, this outer contact 13 is made for good conductor material, this inner insulating layer 12 that the positive charge in this inner wire 10 enters this outer contact 13 is prevented to be made for insulant.
In the present invention, inner core 11 adopts high intensity inner core, and implant 14 adopts weak intensity implant. The inner core 11 of high intensity is for strengthening the tensile strength of conductor of the present invention, for instance, inner core 11 can adopt steel matter to make. The implant 14 of weak intensity is for filling the space between stranded bundles of the plurality of inner core 11 and inner insulating layer 12, and implant 14 and stranded bundles of the plurality of inner core 11 collectively form a substantial inner wire 10. Such as, implant 14 is made for aluminium material. And outer contact 13 can be made for copper or aluminium material.
