FIELD: electricity.
SUBSTANCE: invention relates to linear pin-type high-voltage insulators intended for insulated fixation of wires to metal, reinforced concrete and wooden supports on overhead power transmission lines and pin-type support insulators of distribution devices of stations and substations for voltage of up to 35 kV AC of industrial frequency of 50 Hz. High-voltage insulator comprises metal end terminal for fixation to support cross beam, metal end terminal for fixation of wire and electric insulation part. Insulator differs by the fact that electric insulation part is made of evenly tempered glass with extent of tempering of more than 700 millimicron/cm, and is inseparably connected to end terminal. End terminal is arranged in the form of pipe for placement onto pin.
EFFECT: provides for easy detection of insulator internal insulation breakthrough.
