Transformer oils and GTL technology
Oils based on gas-to-liquid (GTL) technology provide an effective choice of lubrication for use with electrical equipment – from distribution transformers to high-voltage, direct current transformers.
GTL transformer oils – such as Shell Diala S4 ZX-I, Shell Diala S4 ZX-IG and Shell Diala S5 BD – offer some clear improvements over conventional mineral-based products. As well as helping to enhance the protection of your transformer components, they can increase the efficiency of your equipment – including in low-temperature conditions.
Transformer oils based on GTL technology also provide you with consistent performance, helping you to increase the reliability of your equipment. Plus, they are simple to introduce to your lubrication systems due to their compatibility with most conventional transformer oils.
Demonstrate your sustainability credentials with Shell Diala S5 BD
As electricity demand continues to grow, power generation is expanding into diverse and often ecologically sensitive locations. Making sure that your transformers on these sites have a high standard of environmental protection is critical.
A key element of this is biodegradability. From offshore wind to solar farms in the desert, it is important to protect the surrounding natural environment – and reduce the impact of unexpected leaks.
Shell Diala S5 BD is designed to be a high-performance, readily biodegradable oil that gives you peace of mind in operations where performance and environmental impact are both critical priorities. Meeting, and exceeding, industry-standard tests, it helps you to drive the efficiency of your operations while also demonstrating your sustainable credentials.
A step closer to a sustainable transformer
By enabling equipment to handle harsh, cold climates and new environmental needs, Shell Diala S5 BD supports transformer operators in overcoming the biggest challenges they currently face.
Shell Diala S5 BD was successfully tested by Siemens Energy for TenneT’s transformer substation in Schwandorf – currently the biggest three-phase TenneT grid transformer in Germany.
