askarel
|as-ka-rel|
/ˈæskərəl/
trade-name chlorinated dielectric oil (historical/PCB-containing)
Etymology
'askarel' originates from English, specifically as the trade name 'Askarel' coined in the 20th century by manufacturers of dielectric fluids.
'askarel' changed from a proprietary brand name for a specific insulating fluid into a more general term applied to PCB-containing or other chlorinated dielectric oils; after environmental and health regulations on PCBs, the term fell into more restricted, historical usage.
Initially, it meant 'a specific branded insulating fluid'; over time it came to mean 'any PCB/chlorinated dielectric oil', and today it is mainly used historically or in regulatory/technical contexts.
