Composite insulator fault indicator and a cap and pin insulator containing composite insulator fault indicator

摘要

Capsule insulator incorporating an enhanced sensitivity composite insulator injury indicator for use in high voltage overhead insulator chains,consisting of one or more cap insulators and one composite insulator, made of circular sludge (1a),on whose upper surface the codend head (1b) is formed,in which it is deposited, carried out below the lower surface of the toilet (1a),a handle (1d) and a head-mounted (1b) cover (1e),the lower part of the codend (1a) is composed of the ring ribs (1c);is characterised by the fact that around the handle (1d) the bottom of the codend (1a) is covered by a semi-conductive layer (2). The high sensitivity composite insulator injury indicator is characterised by the shape of a cap insulator (1) on the bottom surface around its handle (1d) of the semiconductor layer (2).
