The product adopts a sealed and dust-proof oil tank design, reaching IP44 protection grade, which can adapt to complex outdoor environmental conditions such as light rain and dust. The telescopic pull rod and universal brake wheels make the equipment easy to move and fix. The detachable control box uses an ABS waterproof shell, which can be operated separately from the main unit, improving the flexibility of field operation. Built-in overcurrent, overvoltage and oil temperature protection devices ensure the safety of field testing.
The transformer supports switchable input voltage between 220V and 380V, with a rated output voltage of 20kV and a rated capacity of 20kVA. The oil tank is made of cold-rolled steel sheet with anti-rust treatment, and the insulating oil uses flame-retardant mineral oil. The overall dimensions are 1000mm in length, 700mm in width and 1200mm in height, with a total weight of 280kg. It is equipped with quick-plug high-voltage output interfaces, and the operating temperature range is -20℃ to 50℃.
This test transformer is suitable for withstand voltage test of outdoor power transmission lines, maintenance testing of field substations, cable testing of wind turbine towers, maintenance testing of outdoor distribution equipment, and mobile power testing for emergency repair teams.
