The S11/S13 series covers three-phase oil-immersed distribution transformers for 10 kV, 20 kV, and 35 kV distribution systems. Available capacities span 30–6300 kVA, allowing the transformer to be selected for the network voltage, connected load, and end-user distribution requirements.
The design uses a three-phase, three-limb stepped cylindrical core and concentric winding construction for alignment and short-circuit strength. Published configurations include self-cooled, two-winding, off-circuit tap-changing transformers with Dyn11 or Yyn0 vector groups. Capacity, voltage ratio, tap range, impedance, losses, dimensions, weight, terminals, and accessories must be confirmed for the quoted project configuration.
Where it performs.
- Utility and industrial distribution networks from 10 kV to 35 kV
- Commercial, manufacturing, and infrastructure power distribution
- Project-specific step-down supply to end-user electrical systems
What’s included.
- One S11 or S13 distribution transformer in the accepted project configuration
- Final drawings, nameplate data, test-document scope, terminals, and accessories as stated in the quotation
Specify before delivery.
Confirm utilities, site access, operating environment, consumables, ventilation, PPE, delivery handling, and local requirements before finalizing the configuration.
