These products are primarily designed for photovoltaic (PV) and wind power projects: 1.The unit integrates a transformer, load switch, and high-voltage fuses within a single tank. The load switch features an independent oil chamber isolated from the transformer's main insulation oil, preventing contamination and effectively extending service life. The design offers compact dimensions and easy installation. 2.The product employs an axial split configuration, utilizing specialized structural engineering and manufacturing processes to ensure reliable electrical and mechanical performance, along with enhanced short-circuit resistance. 3.The tank surface undergoes shot blasting followed by powder coating, providing corrosion resistance and an aesthetically pleasing appearance.
