| 1. Scope |
|
1.1 This specification covers synthetic nonflammable electrical insulating liquids of the chlorinated aromatic hydrocarbon-type known as askarels, which are used as an insulating and cooling medium in liquid-filled transformers. This specification includes liquids that were previously available and are still in use in apparatus. 1.2 Askarels covered by this specification are of various types, having components in weight percent in accordance with Table 1. Note 1-The components and the respective percentages given are descriptive of the materials currently in common use and are not intended as part of this specification, which is based on physical and chemical properties. Note 2-Types A through G are PCB-type askarels previously available and still in use in the field. Recently Type H, a non-PCB askarel, was introduced as a retrofit and replacement. Note 3-Current governmental regulations prohibit the manufacture and sale of polychlorinated biphenyls (PCBs). This method serves as a reference for all askarels, PCB and non-PCB. |
