31500KVA 35KV Low Loss Oil Immersed Transformer: Energy-Saving Power Supply Equipment for Industrial Power Grids
Currently, the high-voltage power transmission and distribution industry generally suffers from high equipment losses and poor operational stability. Traditional substation equipment experiences significant energy waste during long-term operation and lacks sufficient adaptability to large-scale industrial and mining applications and photovoltaic power plants. Many enterprises face the practical challenges of high power operation and maintenance costs, high equipment failure rates, and difficulty in ensuring power supply continuity. To address these industry challenges, our factory has launched the 31500KVA 35KV Low Loss Oil Immersed Transformer, which, based on optimized core structure and insulation technology, is precisely adapted to medium and high-voltage power transmission and distribution scenarios. This equipment effectively reduces no-load and load losses. When paired with matching High And Low Voltage Switchgear and Electric Power Converter equipment, it can completely build an industrial power supply system. It is widely used in industrial and mining enterprises, urban power grids, and Combined Photovoltaic Substations. It can replace conventional Dry Type Transformers to meet high-capacity power supply needs, and can also be integrated with Box Type Substations to significantly improve power transmission efficiency, reduce long-term maintenance energy consumption, and ensure the stable and long-term operation of the entire power supply system.
As a core high-capacity medium- and high-voltage transformer, this 31500KVA 35KV Oil-immersed Transformer has undergone refined process upgrades, eliminating the structural shortcomings of traditional equipment. It adopts high-permeability silicon steel sheets and a sealed insulation design, possessing advantages such as low loss, low noise, and strong overload resistance. The equipment’s rated capacity and voltage level are compatible with mainstream domestic industrial and new energy power supply standards. It can withstand long-term continuous full-load operation and is suitable for various installation environments, including outdoor and indoor substations. With strong compatibility, it can be flexibly integrated into various complete power supply systems, providing reliable substation support for large-scale production bases, centralized photovoltaic power stations, and regional power grid transformation projects.
