Product Introduction
The HZG1602 Series Ultra-Light AC/DC Test Transformer is designed for AC withstand, DC withstand and leakage current testing of electrical equipment, insulation materials and power system components.
Compared with conventional oil-immersed test transformers, its lightweight dry-type structure provides lower weight, smaller size and easier field transportation. The system can be configured with a control unit, high-voltage rectifier and measurement components for different AC/DC high-voltage testing requirements.
Available configurations cover 1.5–30kVA capacity, 50–120kV AC output and up to 140kV DC output, with customized voltage, capacity and current options.
