As a result of a thorough investigation into the cause of the poor electrical properties of electric wires when subjected to repeated severe bending, we found that the cause was wear and tear of the enamelled wire strands on the outer periphery, which were intensely pressed against the outer protective insulation layer. This led to the discovery of this idea.

たことにある。[Function] The multicore insulated wire of the present invention minimizes the finished outer diameter of the twisted enameled wire by concentrically twisting a plurality of enameled wires, and a protective insulating layer is formed on the outer periphery of the twisted enameled wire. The finished outer diameter of the multi-core insulated wire is minimized by fully coating the multicore insulated wire, and all of the twisted enameled wires are made of self-lubricating enameled wires, which prevents wear even when the wires rub against each other. Damage can be effectively suppressed, and at least one side of the adjacent strands on the outer periphery is covered with a polyamide-imide enameled wire overcoated with a dense wax blend polyethylene lubricant layer, which prevents the low melting point lubricant from becoming dense wax and hard. Together with the lubricant polyethylene, it exhibits a complex lubricating effect while significantly relieving pressure, and further improves the excellent abrasion resistance inherent to polyamide-imide enameled wire.As a result, these factors work synergistically to create a finished product. The object of the present invention is to provide a highly reliable multi-core insulated wire that exhibits excellent bending resistance and electrical characteristics despite having a small outer diameter.
