Product Information
Product Introduction
Deep® Natural Ester Insulating Oil is a flame-retardant natural ester cooling fluid used in electrical equipment such as transformers. It features excellent environmental, fire safety, chemical, and electrical performance. This insulating oil contains no petroleum, halogens, silicone resins, or any other harmful substances, and can rapidly and completely biodegrade in soil and water environments. Tests show that Depster Natural Ester Insulating Oil achieves 98% degradation within 28 days.
