What does the SXBP system test?
It is mainly used for high-voltage AC withstand and insulation testing of equipment such as power cables, GIS, transformers, circuit breakers and other HV electrical apparatus.
Why is resonance technology suitable for cable testing?
Power cables have distributed capacitance, which can create a significant capacitive load during AC testing. Series resonance technology works with this capacitance to establish a resonant circuit and generate the required high-voltage output efficiently.
Can the system be used for underground cable projects?
Yes. The SXBP series is suitable for high-voltage and EHV underground cable testing, including long-distance cable systems.
What voltage classes can be tested?
The system can be configured from 200 kV to 2000 kV, depending on the required testing conditions.
What capacity is available?
The available rated capacity range is 300 kVA to 20,000 kVA.
