This lightweight oil-immersed test transformer prioritizes portability and operational stability, addressing the long-standing pain point of heavy, hard-to-transport traditional test equipment. It adopts a lightweight aluminum alloy oil tank, reducing overall weight by 30% compared to standard industrial models, enabling 2-3 operators to easily transport and set up the device on small-scale job sites. The precision voltage regulation mechanism ensures output voltage error stays within ±0.5%, delivering highly accurate test results. A built-in real-time oil temperature monitoring system automatically triggers an alarm when the oil temperature exceeds the safe threshold, preventing equipment damage caused by prolonged overheating. The fully sealed oil tank design eliminates oil leakage risks, reducing environmental pollution and lowering long-term maintenance costs. Additionally, it can be seamlessly matched with external control consoles and measuring instruments to form a complete voltage test system, adapting to diverse testing requirements across different industries.
This oil-immersed test transformer has a rated AC output voltage range of 0-50kV and a rated capacity of 50kVA, suitable for most low-voltage electrical testing scenarios. It supports two input voltage options: 220V and 380V single-phase, compatible with most standard household and industrial power supplies. With an F-class insulation grade, it offers excellent long-term insulation performance under continuous operating conditions. The natural oil circulation cooling mode ensures stable heat dissipation during long testing sessions, maintaining consistent equipment performance. The net weight of 85kg and compact overall dimensions make it easy to move and store. It meets the safety standards of IEC 60601 and GB/T 19483, with a protection grade of IP20 to prevent dust and small foreign objects from entering the equipment. The output waveform is a standard sine wave, and the voltage regulation accuracy is within ±0.5%, ensuring reliable and accurate test data for every operation.
This 50kV oil-immersed test transformer is widely used in multiple electrical testing scenarios, including voltage withstand tests for low-voltage electrical appliances such as circuit breakers, relays, and power sockets, insulation performance testing of rubber and plastic materials, and small-scale transformer and reactor performance verification. It is suitable for electrical equipment manufacturing plants, power distribution station maintenance teams, third-party quality inspection institutions, and university electrical engineering teaching labs. The device provides accurate and reliable voltage testing services, helping users identify potential insulation defects and safety hazards in electrical products and materials, ensuring the safety and compliance of final products. It is also ideal for on-site maintenance and testing of small power distribution equipment in residential communities and commercial buildings.
