Product Description

Shell Diala S4 ZX-IG is a premium, fully inhibited electrical insulating oil specifically engineered to meet the severe dielectric stresses and gas-absorbing challenges of specialized high-voltage equipment, such as instrument transformers, bushings, and X-ray machinery. Manufactured from ultra-pure, zero-sulfur base oils using Shell’s advanced Gas-to-Liquid (GTL) technology, it provides exceptional compositional consistency and superior resistance to fluid aging. This advanced formulation delivers outstanding oxidation performance, exceeding the highest industry standards to provide an extended operational lifetime and reduce the degradation rate of both the oil and the internal insulating paper. Being completely sulfur-free, it eliminates the risk of copper corrosion within the system without requiring any additional passivation additives. In addition to superior protection, Shell Diala S4 ZX-IG is uniquely designed to absorb gases like hydrogen that can develop under partial discharge conditions, ensuring safer and more reliable operations under high voltage gradients. Its excellent low-temperature fluidity and thermodynamic properties promote highly efficient heat transfer inside the transformer, even during extreme cold-weather startups. The oil is also fully miscible with conventional naphthenic mineral oils, simplifying product transitions and top-ups. This large-scale 209L drum size is the ideal solution for heavy industrial power grids, power generation stations, and utility networks that demand maximum equipment efficiency, robust transient voltage protection, and long-term service reliability.
