To provide an insulated wire that can increase in a partial discharge starting voltage, prevent deterioration of an insulator, and not cause worsening of an occupancy ratio, a coil that uses the insulated wire, a variable-thickness insulating tape used in manufacture of the insulated wire, and a manufacturing method of the same. The above-described problem is solved by an insulated wire (10) for a coil, comprising a conductor (1), and insulating coatings (2, 3) provided on an outer periphery of the conductor (1). The insulated wire (10) is constituted by the thick insulating coating (3) for an area where voltage increases and partial discharge readily occurs, and the thin insulating coating (2) for an area where the voltage does not increase and partial discharge does not readily occur, when the coil is wound. The thick insulating coating (3) and the thin insulating coating (2) are repeatedly provided at desired intervals. The above-described problem is solved by a coil (40) obtained by winding such an insulated wire (10) and configured so that the insulating coating (3) of the insulated wire (10) in an area where partial discharge readily occurs is thick, and the insulating coating (2) of the insulated wire (10) in an area where partial discharge does not readily occur is thin.

An insulation defect detection method for magnet wire coating includes: a running step of causing a magnet wire to run in a line direction; a first discharge detection step of detecting a first discharge by applying AC voltage to a measurement point on the running magnet wire; a second discharge detection step of detecting a second discharge by applying AC voltage to a measurement point on the magnet wire after the first discharge is detected; and a determination step of determining whether or not the magnet wire coating has an insulation defect by comparing the first discharge with the second discharge.

A helically wound insulated twinax cable reduces cable dielectric loss by increasing the percentage of air in the dielectric filler surrounding the signal conductors. The helical insulator wire winding further provides mechanical support and reduces the risk of creating an electrical short-circuit. This will improve differential signaling capability of the two-conductor cable and enable longer cable range.
