Shell Naturelle Transformer Fluid S4 I
Advanced Synthetic Electrical Insulating Fluid
Application of Shell Naturelle Transformer Fluid S4 I
Industrial transformers. Electrical insulating fluid for power and distribution transformers, subject to demanding environmental and fire safety requirements, e.g. traction transformers and wind turbine applications.
Transformers in electric locomotives. Insulating and cooling fluid for mobile railway transformers.
Properties and Benefits of Shell Naturelle Transformer Fluid S4 I:
- Low flammability. Shell Naturelle Transformer Fluid S4 I has low flammability characteristics, making it particularly suitable where mineral oil is not acceptable for safety reasons.
- Readily biodegradable. Due to the nature of the synthetic ester base fluid, it is readily biodegradable according to the OECD 301B biodegradability test. Shell Naturelle Transformer Fluid S4 I is the product of choice when environmental considerations are the highest priority.
- Extended oil life. The fluid has excellent ageing stability (oxidation resistance), enabling long service life without oil change. Transformer protection. The fluid is compatible with commonly used transformer components.
- System efficiency. The fluid enables effective heat transfer within the equipment.
