ELECTRIC INSULATOR Russian patent published in 2010 - IPC H01B17/14

Abstract RU 2391728 C1

FIELD: electricity.

SUBSTANCE: insulator comprises dielectric shell, end terminals and bearing element formed from glass fiber threads impregnated with binder. Bearing element has alternating cross section, which reduces from its middle part to end terminals. Bearing element may have multilayer structure that varies layerwise from the middle of the bearing element to its end terminals. Basalt glass tissue is used as threads of glass fibre.

EFFECT: increased strength characteristics of electric insulator used in contact networks of tram and trolleybus.
