Helping Transformer Manufacturers Conduct Business Without Compromise

Kalla Electrical System is a leading transformer manufacturer in Indonesia, providing the equipment needed for large government infrastructure programmes. To meet the demands of their expensive assets – and of the communities their equipment serves – the company needs a transformer oil that has been proven to provide reliable performance and can offer:

  • An extended oil life
  • Operational simplicity
  • High levels of component protection

Formed from a gas-to-liquids base oil and approved by global OEMs, Shell Diala S4 ZX-I is designed to help power operators set their transformers up for success in the face of increasingly challenging conditions, courtesy of high oxidation stability, zero sulphur and fewer miscibility concerns.
