Voltage stabiliser used in high tension cable insulation - based on polyolefin contg. di:aryl ketone carbonic acid or its ester

Electric voltage stabiliser used in high tension cable insulation is based on a polyolefin contg. 0.1-5 (0.5-2) wt. % of diaryl ketone carbonic acid or its ester. Since the stabiliser at the operative temp. of the cables is a solid it stays permanently in the cable and reduces diaelectric losses. St...

Zusammenfassung:	Electric voltage stabiliser used in high tension cable insulation is based on a polyolefin contg. 0.1-5 (0.5-2) wt. % of diaryl ketone carbonic acid or its ester. Since the stabiliser at the operative temp. of the cables is a solid it stays permanently in the cable and reduces diaelectric losses. Stabiliser may also include benzophenon-2-carbonic acid or an ester derived from an aromatic alcohol and the aromatic nuclei may carry other substits.
