KEY-147 High Performance Insulating oil
Product Highlights
High Purity | Good Solubility | Good Stability |
High Dielectric Constant | Good Lubricity | Good Biodegradability |
Product Introduction
All equipment for handling KEY-147 vegetable insulating oil (such as hoses, pipes, oil tanks, and oil filtering equipment) should be kept clean and should be used exclusively for vegetable insulating oil.
If the oil sample previously treated by the equipment is mineral insulating oil or synthetic ester insulating oil, it can be flushed with KEY-147 vegetable insulating oil before use. If the oil treatment equipment was previously filled with silicone oil, it cannot be treated with 147 vegetable insulating oil.
Equipment with residual vegetable insulating oil should be sealed and isolated from air and pollutants. When storing vegetable insulating oil in containers such as oil drums, oil tanks, and oil storage tanks, the oil surface should be sealed and covered with dry nitrogen or dry inert gas.
