Shell Diala S4 ZX-IG

Product Overview

Shell Diala S4 ZX-IG is the most advanced transformer oil in the Shell Diala series, developed to meet the evolving demands of modern high-voltage transformers and harsh operational environments. It is based on GTL (Gas-to-Liquid) technology, delivering exceptional purity, thermal stability, and dielectric performance.

Designed for the latest generation of compact, high-load, and long-lifecycle transformers, Shell Diala S4 ZX-IG supports extended oil life, minimal maintenance, and enhanced reliability—making it ideal for critical power infrastructure.

Key Features & Benefits

• Exceptional Oxidation Resistance
  Greatly reduces sludge formation and degradation over time, even under high electrical and thermal stress.

• Zero Corrosive Sulfur Content
  Meets IEC 62535 standards—no risk of oil-related copper corrosion, protecting transformer windings and internals.

• Superior Thermal Stability
  Maintains excellent cooling and dielectric properties under overload conditions and low-start temperatures.

• GTL Base Oil Purity
  Free of impurities typically found in conventional mineral oils, ensuring consistent and reliable insulation.

• Supports Extended Transformer Life
  Helps reduce outages and maintenance frequency while increasing transformer uptime and efficiency.

Applications

• High-voltage and extra high-voltage power transformers

• Grid and utility transformers with high reliability requirements

• Compact or sealed units with reduced cooling capacity

• Transformers exposed to wide temperature ranges or overload operation

• Locations where longer service intervals and minimal downtime are crucial
