Product description:

WXT's liquid-filled substation transformers through 138kV are designed,built, and tested in accordance with interntional standards including IEC 60076, GB1094, ANSI C.57, US DOE Efficency, CSA, NEMA ,and IEEE as applicable. The insulating liquid can be mineral oil ( ON type ), high flash point ester fluid, and silicon oil ( KN type ).  The appllications are for electric utilies, commericial and industrial. The OLTC could be built on LV side

The transformers can be designed and built with conservator or hermetically-sealed system.

The voltage ratings up to: 138kV  AC 50/60Hz  - Substation Type
The KVA ratings up to: 100 MVA
Typical Lead time: 2 months  ExWork
Annual Capacity:100 units ( 69kV - 138kV )
