31.5 MVA 220 KV Oil-Immersed Transformer with OLTC IEC Certified for Grid Substations Cooper Core
31500 kVA 220 kV Oil-Immersed Main Power Transformer
Reliable Backbone for High-Voltage Transmission Systems
The 31500 kVA 220 kV oil-immersed main power transformer is engineered as a core asset for high-voltage transmission and substation applications. Designed in full compliance with IEC 60076 and relevant international standards, it delivers long-term operational reliability, excellent voltage regulation capability, and optimized life-cycle cost performance.
This transformer is widely deployed in 220 kV transmission substations, power plant grid-connection systems, and large industrial self-owned substations, especially in regions undergoing power grid expansion and upgrading.

Regional Hub Substation Applications
Stability at the Hub Level, Bearing Every kWh of Electricity
Core Application: Serving as the backbone of power distribution networks, these substations bridge the main grid and distribution systems.
Critical Challenges in Hub Substations
- Load fluctuations (peak demand or line failures) exceeding standard short-circuit resistance, causing winding deformation and power outages
- Chronic operational losses—excessive no-load and load losses—violating energy efficiency standards and contradicting carbon neutrality goals
- Traditional transformer tanks prone to deformation and insulation degradation, with 15-year lifespan requiring frequent costly maintenance
In urban and industrial power distribution systems, regional hub substations play a pivotal role as bridges: handling input voltages of 220kV or higher while consistently stepping down to medium-voltage distribution networks, ensuring uninterrupted operation for dozens of distribution terminals.
