Key Features

• Epoxy Resin Casting and Enclosed Structure：The JSZW12A - 12R Indoor Three - phase Epoxy Resin voltage transformer features an epoxy resin casting and full - enclosed construction. This not only provides excellent electrical insulation but also protects the internal components from dust, moisture, and other contaminants. As a result, it is highly suitable for indoor use, ensuring stable operation in various indoor environments.
• Accurate Three - phase Voltage Measurement：Designed to precisely measure three - phase voltages in single - phase or three - phase AC circuits with a frequency of 50Hz or 60Hz and a highest equipment voltage of 12 kV, it enables reliable voltage monitoring for power systems. The transformer's advanced design and high - quality materials contribute to minimizing measurement errors, ensuring that the measured voltage values accurately reflect the actual system voltages.
• High Reliability and Low Core Magnetism：With a core that exhibits low magnetism, the transformer reduces energy losses during operation, enhancing its overall efficiency. Additionally, the high - reliability design ensures that it can continuously operate under normal working conditions for an extended period without significant performance degradation. This makes it a dependable choice for power system applications where continuous and accurate voltage transformation is crucial.
• Large Creepage Distance of External Insulation：Featuring a large creepage distance of external insulation, the transformer can effectively withstand high - voltage stress and prevent electrical breakdowns caused by surface leakage currents. This is particularly important in environments where there may be humidity, pollution, or other factors that could affect the insulation performance. It helps maintain the integrity of the electrical insulation and ensures safe and stable operation of the transformer.
