Abstract

Изобретение относитс к электротехнике, а именно к радиочастотным кабел м. Целью изобретени вл етс повышение теплостойкости кабел и коррозионной стойкости внутреннего проводника при одновременном сохранении уровн электрических характеристик. На внутренний проводник с положительным перекрытием намотана изол ционна лента, поверх которой расположена монолитна изол ци , наружна поверхность которой с внешним проводником образуют выполненные по спирали полости. При этом шаг спирали указанной полости равен шагу намотки ленты. 1 ил.The invention relates to electrical engineering, namely to radio frequency cables. The aim of the invention is to increase the heat resistance of the cable and the corrosion resistance of the inner conductor while maintaining the level of electrical characteristics. An insulating tape is wound on the inner conductor with a positive overlap, over which there is a monolithic insulator, the outer surface of which with the outer conductor is formed by spiral-shaped cavities. In this case, the pitch of the spiral of the indicated cavity is equal to the pitch of the tape winding. 1 il.

Description

Изобретение о носитс к электротехнике , а Именно к радиочастотным кабел мThe invention is about electrical engineering, and specifically for radio frequency cables

Целью изобретени вл етс повыше ниетеплостойкости кабел и коррозионной стойкости внутреннего проводника при одновременном сохранении уровн электрических характеристикThe aim of the invention is to improve the heat resistance of the cable and the corrosion resistance of the inner conductor while maintaining the level of electrical characteristics.

На фиг 1 показан миниатюрный радиочастотный кабель, продольное сечение, на фиг 2-го же, поперечное сечение.Fig 1 shows a miniature radio frequency cable, a longitudinal section, in Fig 2 of the same, a cross section.

Кабель содержит гутренний проводник 1, внутренний слой изол ции в виде обмотхм лентой 2, монолитный слой 3 изол ции и внешний проводник 4. Между монолитным слоем изол ции и внешним проводником имеютс воздушные полости 5The cable contains a conductor conductor 1, an inner layer of insulation in the form of tapes 2, a monolithic layer 3 of insulation and an outer conductor 4. There are air cavities 5 between the monolithic layer of insulation and the outer conductor 5
