The YTB-20 Series (100kV–140kV) is a professional-grade high-voltage test system designed for evaluating the insulation integrity of electrical equipment, materials, and switchgear. Ideal for medium-voltage substations and transformer yards, it offers high-precision AC and optional DC testing capabilities. With a two-part configuration, this system allows operators to manage high-voltage testing from a safe distance using a variac-based control unit equipped with real-time voltage, current, and time indicators. This model is particularly valuable for applications requiring DC up to 140kV via a rectifier module.

Applications:

• High-voltage withstand testing of switchgear and circuit breakers
• Dielectric and insulation testing of MV transformers and cables
• Type testing and quality assurance in HV manufacturing
• Substation component validation for utilities and grid operators
• Electrical material insulation resistance assessment
