Abstract: The high-voltage outdoor bushing comprises a conductor (2) extended along an axis (1), a condenser core (3) and an electrically insulating polymeric weather protection housing (7) moulded on the condenser core (3). The condenser core (3) contains an electrically insulating tape (4) which is wound in spiral form around the conductor (2), capacitance grading insertions (5) arranged between successive windings of the tape (4) and a cured polymeric insulating matrix embedding the wound tape (4) and the capacitive grading insertions (5). A moisture diffusion barrier is incorporated into the condenser core (3) prior to moulding the weather protection housing (7). Such a bushing is distinguished by an excellent storage and operation stability under hot and wet weather conditions.
