220KV OIL-IMMERSED TRANSFORMER

220kV oil-immersed power transformers are key power transmission and transformation equipment for the main power grid. They are available with on-load tap changers or off-circuit tap changers, and can be configured with 2 or 3 windings. Insulating oil is used as both insulation and cooling medium, adopting ONAF cooling mode. Optimized via multi-physics simulation, the transformers adopt high-permeability silicon steel sheets and reinforced windings, featuring strong short-circuit resistance, low loss, low partial discharge and low noise. Intelligent monitoring modules can be installed optionally. Compliant with GB and IEC standards, they are widely applied in 220kV substations, power plants, new energy bases, petrochemical and rail transit projects.

252KV GAS-INSULATED METAL-ENCLOSED SWITCHGEAR (GIS)

252kV Gas-Insulated Metal-Enclosed Switchgear (GIS) uses SF gas as insulating and arc-extinguishing medium, serving as the core switchgear for the 220kV voltage level. Adopting modular integrated design, the product features compact structure and small footprint, with low partial discharge, high reliability and low maintenance workload. Optional intelligent online monitoring modules can collect real-time operating data of the equipment. Compliant with GB and IEC standards, it is widely used in power transmission and transformation projects such as substations, new energy bases, rail transit, petroleum and petrochemical industries.

550KV-CLASS INTELLIGENT OIL-IMMERSED POWER TRANSFORMER

550kV-class intelligent oil-immersed power transformer serves as the core equipment for EHV main power grids, supporting 2/3 winding configurations and adopting insulating oil for insulation and cooling. Optimized by multi-physics simulation, it applies high-permeability silicon steel sheets and reinforced winding structure, featuring strong short-circuit resistance, low loss, low partial discharge and low noise. Equipped with intelligent monitoring modules, it can monitor operating status in real time. Compliant with GB and IEC standards, it is widely used in large substations, power plants and new energy power transmission projects.
