Electrical properties, oxidation resistance is poor, but good antioxidant susceptibility

Transformer oil to replace the electrical switch oil , which can not meet the required electrical switch oil insulating properties and low temperature properties .  electri cenergy meter  equipment is running , the occurrence of short-circuit current , oil often produce large amounts of free carbon , oil blackened , dielectric strength would drop dramatically ; short-circuit breaking generally occurs twice , it is necessary to stop oil treatment equipment , and thus had to frequently change oil , increasing fuel consumption . Dushanzi oil refinery production breaker  mcb circuit breaker , in particular the rare , far from meeting market demand. French import breaker better quality oil , but the variation in viscosity , slow settling of free carbon , colloid state easily , difficult to remove . Cycloalkane has good electrical properties, poor oxidation resistance , but the susceptibility of good antioxidants , and generally low pour point is an ideal  Voltage stabilizer  the insulating oil . So are the first choice of the world production of crude oil naphthenic insulating oil . Because less naphthenic crude oil reserves , so it developed from the middle of the base , even from the paraffin-based oil producing electrical switches . To meet the high-voltage electrical switch oil oil needs , we hydrogenated oils, benzene as raw material, developed in line with specifications SH/T0205-92 electrical switch oil, which are high-grade lubricants .
