20000 kVA 35 kV Oil-immersed Transformer for Industrial Power Grid Stabilization and Distribution
In the current high-voltage power distribution industry, large industrial and mining power plants commonly suffer from unstable voltage regulation and high equipment losses under heavy loads. Many enterprises face challenges such as poor adaptability of traditional Power Distribution Equipment, high operation and maintenance costs, and inability to meet large-capacity power supply demands. To address these issues, this 20000 kVA 35 kV oil-immersed transformer utilizes mature non-excitation voltage regulation technology and a fully sealed oil-immersed structure design, precisely adapting to large-capacity high-voltage power distribution scenarios. The equipment can stabilize grid voltage, reduce operating energy consumption, and is compatible with various power supporting equipment, significantly improving the power supply stability and security of industrial and mining power plants, photovoltaic power plants, and municipal power grids, effectively reducing equipment failure downtime and lowering long-term operating costs. In the construction of a complete power system, this equipment can be flexibly combined with Dry Type Transformers and Box Type Substations to adapt to the power distribution layout requirements of different sites. It can also be used with High And Low Voltage Switchgear and Electric Power Converters to complete the construction of a complete power transmission and voltage stabilization system. It is widely applicable to the expansion and renovation projects of conventional industrial and mining substations and Combined Photovoltaic Substations, making it a core main equipment for high-voltage, high-capacity power distribution scenarios.
คุณสมบัติผลิตภัณฑ์
1. Stable and Reliable Voltage Stabilization Performance: Adopting a non-excitation manual voltage regulation structure, it boasts high voltage regulation accuracy and a low failure rate.
