HIGHHMOLECULAR COMPOSITION FOR HIGHHVOLTAGE INSULATION

摘要

An improved high voltage insulating material comprising one or more polymers and an anti-tracking and erosion inhibiting composition comprising a hydrate of alumina and one or more compounds selected from the groups consisting of nickel phosphate, phosphinic acid or a derivative thereof, phosphonous acid or a derivative thereof, and phosphonic acid or a derivative thereof. The composition functions to prevent failure by tracking and to substantially retard failure by erosion.
