Power Isolation transformer: SGGF isolation transformer is used to solve the power grid problems which are caused by the photovoltaic power generation,such as harmonic, flickering, DC magnetic bias, and over voltage. Transformers are usually used between power grid and grid-connected inverter which can isolated inverter and sent the power back to grid. Characteristic of Power Isolation transformer: Standard capacity: 50KVA/100KVA/250KVA/500KVA Rated voltage:400V/290V Connection group:YN.yn0； Impedance: 3-5% Efficiency:＞98% Overload capacity：15% Insulation class：H； Low?inrush?current； Three anti-paint treatment； Temperature rise ≤80K； Meet 100% load； Electric intensity: AC3000V/min, leakage current＜5mA Under rated power, winding temperature-rise F, less than 100K, insulation system H. Meterial： High quality silicon steel sheet iron core, which achieves low no-load loss and noise. Enamelled rectangular wire for small capacity, aluminum foil for large capacity, producing with vacuum pressure impregnation which makes transformer high mechanical strength and moistureproof ability. Ssrvice life：more than 30 years； Application of Power Isolation transformer: Photovoltaic power generation High Power UPS, Inverters Lighting Machine Tool Electrical Apparatuses Electrical Machinery And Equipment Medical Equipment Rectifying Device
