FIELD: electricity.
SUBSTANCE: inductance coil comprises an insulating frame with the central axis divided by insulating partitions into sections, and a winding made of an insulated wire passed from section to section. The height of wire laying to sections is equal to the height of the partition plus one diameter of the insulated wire. The passage of the wire from section to section is made by its coiling over the partition between the sections. The number of turns in one section is selected so that voltage between any two turns in one section does not exceed the permitted breakdown voltage of the wire insulation. The coil pitch is permanent for the turns along the whole length of the winding.
EFFECT: reduced time of coiling, reduced weight and dimensions due to the increased density of turns laying and improved operational reliability.
