Shell Naturelle Transformer Fluid S4 I 1000 L (Bulk Container)
Shell Naturelle Transformer Fluid S4 I
Advanced synthetic electrical insulating fluid
Applications Shell Naturelle Transformer Fluid S4 I
Industrial transformers. Electrical insulating fluid for power and distribution transformers, which may have advanced requirements regarding environment and fire protection e.g traction transformers and wind turbine applications.
Transformers in electrical locomotives. Insulating and cooling fluid for mobile railroad transformers.
Features and Benefits of Shell Naturelle Transformer Fluid S4 I are:
- Low flammability. Shell Naturelle Transformer Fluid S4 I has low flammability characteristics. This makes the fluid particularly suitable when a mineral oil is not acceptable for safety reasons.
- Readily biodegradable. The nature of the synthetic ester base fluid makes it readily biodegradable, as per the OECD 301B biodegradability test. Shell Naturelle Transformer Fluid S4 I is the product of first choice whenever environmental aspects have the highest priority.
- Extended Oil Life. The fluid has very good ageing stability (resistance to oxidation) which allows a long service period without any oil change.
- Transformer protection. The fluid is compatible with commonly used transformer components
- System Efficiency. The fluid ensures that heat transfer inside the machinery is effective.
