FIELD: electricity.
SUBSTANCE: high-voltage bushing insulator of outdoor installation comprises a conductor (2), stretching along an axis (1), a core (3) and an electrically insulating polymer body (7), protecting against atmospheric effects, cast on the core (3). The core (3) comprises an electrically insulating tape (4), which is wound in the form of a spiral around the conductor (2), capacitor inputs (5), arranged between adjacent turns of the tape (4), and a hardened polymer insulating binding medium, introduced into the wound tape (4) and into capacitor inputs (5). Inside the core (3), prior to body (7) casting, protecting against atmospheric effects, there is a diffusion barrier for moisture mounted in.
EFFECT: insulator differs by supreme stability in storage and operation under hot and moist conditions.
