Through VanTran’s collaboration with Shell Lubricant Solutions, we deliver superior reliability and performance with Shell Diala S4 ZX-IG — insulating fluid based on advanced Shell gas-to-liquids (GTL) technology. Engineered for excellent low-temperature viscosity, this oil ensures efficient heat transfer inside transformers, even in extreme cold conditions. Compared to traditional naphthenic oils, Shell Diala S4 ZX-IG offers enhanced thermal stability that slows the aging of both oil and insulating paper, extending transformer life. Trust VanTran and Shell to help protect your transformers and maintain optimal performance in all conditions.
