For dry-type transformers having a 220 [degrees] C insulating system and a winding hot-spot temperature of 220 [degrees] C, and with no unusual operating conditions present, the 20-yr life expectancy is a reasonable time frame.he 80 [degrees] C transformer requires operation at 75% or more of full load for a 2-yr payback, and at 100% load to payback in 1 yr over the 150 [degrees] C transformer.
Exposure to arsenic through drinking water is a great threat to human health. Arsenic is a carcinogen and its consumption can negatively affect the gastrointestinal tract and cardiac, vascular and central nervous systems.
Some of the long-term health effects of arsenic exposure include various types of cancer, cardiovascular disease and diabetes, medical experts say. Of the two forms of arsenic, organic and inorganic, the inorganic version is accepted to be hundreds of times more toxic, scientists say. The arsenic in the defendant wines is the inorganic type, according to the lawsuit.
