FIELD: railway transport; high voltage contact system. SUBSTANCE: insulator has hollow bearing rod made of glass plastic and bushings, each made of truncated cone and cylinder mated with each other. Bushings are press-fitted in bearing rod and are provided with channels through which rod is filled in with foamed plastic filler. End face sections of rod are coupled through bushings by threaded joint with end terminals. Each end terminal is made of truncated cone and cylinder mated with each other. EFFECT: improved reliability of operation. 1 dwg

Использование: в устройствах высоковольтной контактной сети электрифицированных железных дорог. Сущность изобретения: изолятор содержит полый несущий стержень из стеклопластика и втулки, каждая из которых выполнена из сопряженных между собой усеченного конуса и цилиндра. Втулки запресованы в несущем стержне и имеют каналы, через которые стержень заполняют наполнителем из вспененной пластмассы. Концевые участки стержня связаны через втулки резьбовым соединением с оконцевателями, каждый из которых выполнен из сопряженных между собой усеченного конуса и цилиндра.Usage: in devices of high voltage contact network of electrified railways. The inventive insulator contains a hollow supporting rod made of fiberglass and bushings, each of which is made of a truncated cone and cylinder mating together. The bushings are pressed into the carrier rod and have channels through which the rod is filled with a filler of foam plastic. The end sections of the rod are connected through bushings with a threaded connection to the terminators, each of which is made of a truncated cone and a cylinder mating with each other.
