  •  Step down transformer

    The voltage level of step-down transformer is 1440v 1140V 690V 660V 575v515v500v 480v 460V 440V 415V 400V and other different voltage levels. The voltage level of step-down transformer is 1440v 1140V 690V 660V 575v 515v 500V 480v 460V 440V 415V 400V. Our company can design according to the requirements, using imported silicon steel sheet, high quality oxygen free copper wire, small volume and good quality, It is widely used in imported equipment and different voltage levels abroad. The judgment of the primary secondary coil of transformer depends on whether the transformer is a step-up or step-down transformer. If the transformer is a step-up transformer, the low-voltage coil is the primary, and the high-voltage coil is the secondary; if the step-down transformer, the high-voltage coil is the primary, and the low-voltage coil is the secondary. Technical index capacity: 0.5kva-1600kva input voltage: 380V output voltage: 400V 415V 480v 500V 515v 660V 690V It can be used for long-term operation of over load voltage (1.60hz) with rated output voltage of more than or equal to 1.60hz Rise: ≤ 60 ℃ insulation resistance: ≥ 150m Ω electrical strength: 3000VAC / 1min design life: 20 years working environment: temperature: - 20 ~ + 50 ℃ humidity: ≤ 95% RH non condensing workplace: non corrosive gas and conductive dust safety standards: products meet international national standards such as vde0550, iec439, jb5555, gb226, etc. cooling method: dry air cooling model specification product structure diagram

    model: SG/SBK
