Grid-level power transmission and distribution
oil-immersed transformer
High-efficiency and durable transformers engineered for utility networks, industrial facilities, renewable energy projects, and infrastructure applications.
Product Overview
Oil immersed transformers use high-quality mineral oil or environmentally friendly insulating fluid as both insulation and cooling medium.
The transformer core and windings are immersed in insulating oil, providing excellent heat dissipation capability and stable electrical performance for medium and high-power applications.
Strict industrial standards
Core technical parameters
Before leaving the factory, each transformer undergoes strict tests for frequency multiplication withstand voltage and partial discharge. The energy consumption indicators of each transformer are all superior to the national standards.
10kV Series
The Workhorse of Urban Distribution
35kV Series
The Bridge for Regional Power Supply
As distribution transformers, they have a primary rated voltage of 10kV and typically step down to 400V. Widely installed in residential areas, commercial buildings, light industry, and rural grids, with single-unit capacities typically ranging from 30kVA to 2500kVA. Their compact, hermetically sealed design is maintenance-free, and the low-loss core with high-quality windings guarantees long-term operational economy.
