A LEADING, UNINHIBITED ELECTRICAL INSULATING OIL

Shell Diala S2 ZU-I is a fluid designed to protect your valuable equipment. Widely recognised and approved by leading equipment manufacturers, it is non-corrosive to copper and does not require a copper passivator, as proved in the latest copper corrosion tests. Manufactured from highly refined mineral oils, it has resistance to oil degradation by oxidation and good low-temperature properties, which are vital for efficient heat transfer inside the transformer, even at low temperatures.

A LEADING, UNINHIBITED ELECTRICAL INSULATING OIL

Shell Diala S2 ZX-A is a fluid designed to protect your valuable equipment. Widely recognised and approved by leading manufacturers, it is noncorrosive to copper and does not require a copper passivator, as proved in the latest and most severe copper corrosion tests. Manufactured from highly refined mineral oils, it resists oil degradation by oxidation and has good low-temperature properties, which are vital for efficient heat transfer inside the transformer, even at low temperatures.

SHELL’S PREMIUM INHIBITED ELECTRICAL INSULATING OIL

Shell Diala S3 ZX-I is a state-of-the-art, inhibited electrical insulating oil. It is manufactured from specially refined mineral oils and has an ultra-low sulphur content and long-life characteristics. In addition, it is widely recognised and approved by leading equipment manufacturers as being non corrosive to copper and not requiring a copper passivator, as proved in the latest and most severe copper corrosion tests. It also has good low-temperature properties, which are vital for efficient heat transfer inside the transformer, even at low temperatures.

SHELL’S PREMIUM INHIBITED ELECTRICALINSULATING OIL WITH ENHANCED GAS-ABSORBING CHARACTERISTICS

Shell Diala S3 ZX-IG is a state-of-the-art, inhibited electrical insulating oil. It is manufactured from highly refined mineral oils and has long-life characteristics. Crucially, it has gas-absorbing characteristics that make it an ideal choice for very high voltage, direct-current (HVDC) transformer applications and
instrument transformers and bushings. In addition, it is widely recognised and approved by leading equipment manufacturers and is non-corrosive to copper, as proved in the latest and most severe copper corrosion tests. It also has good low-temperature properties, which are vital for efficient heat transfer inside the transformer, even at low temperatures.
