This series of products is designed and manufactured according to the test protection requirements of high-voltage lightweight high-voltage test transformers. There are various models and parameters available, and the products are divided into structural forms such as pointer control boxes, manual control boxes, automatic control boxes, intelligent operation consoles, and manual operation consoles.

1. It has high voltage, low voltage current, zero position indication, power indication, working indication, and timing indication.
2. Equipped with overcurrent protection, zero start protection, and audible and visual language alarm reminders.
3. Adopting a new type of time relay, the timing range is wider (1S-99H).
4. Adopting a new type of current relay, it is more precise and reliable, ensuring personal and equipment safety.
5. Adopting a combination of hardware and software anti-interference technology, the performance is stable and the anti-interference ability is strong.
6. The high-voltage coil of the test transformer is a cylindrical multi-layer tower, made of high-quality polyester enameled wire and high voltage insulation material.
7. It has the characteristics of light weight, small size, easy mobility, and superior performance.
