Features Shell Diala S4 ZX-I
+ Extended oil life
Shell Diala S4 ZX-I is an inhibited insulating oil that performs exceptionally well in industry-standard oxidation tests and provides extended oil life. It is particularly suitable for use in high-load applications.
+ transformer protection
Shell Diala S4 ZX-I is made from a sulfur-free * base oil, which significantly reduces the risk of copper corrosion, even without the addition of passivators or other additives.
All relevant copper corrosion tests are met: DIN 51353 (silver strip test), ASTM D1275 and the new tests IEC 62535 and ASTM D1275B. More reliability due to a higher flash point. * Sulfur content is below 1 ppm (detection limit of · ASTM D5185).
Moreover, we know that Shell Diala S4 ZX I is also used as Immersion Cooling Fluid for cooling servers as used in crypto mining Cloud computing and blockchain technology.
+ System Efficiency
The very good flowability at low temperatures of Shell Diala S4 ZX-I enables safe heat transfer in transformers, even at low starting temperatures.
Shell Diala S4 ZX-I is manufactured and dried by a special process, which gives it a low water content and a high breakdown voltage on delivery. This allows the use of the oil without additional “drying” in many applications.
