Product performance characteristics
1. Stability and anti-interference: Thanks to the uniform electric field distribution characteristics of the gas medium and the sealed steel shell structure, this equipment exhibits good electrical performance. Its local volume can usually be well controlled, which is conducive to obtaining more authentic and accurate test data. The sturdy shell also provides considerable mechanical strength, capable of handling conventional transportation and on-site operations.
2. Convenient maintenance and observation: Equipment is usually designed with pressure observation windows or pressure gauges, making it easy for operators to intuitively monitor the internal gas pressure conditions. This provides a visual basis for daily inspection and maintenance of equipment status.
3. Wide adaptability: The product has a wide range of voltage levels, which can meet the voltage withstand test requirements of various common electrical equipment from low voltage to high voltage levels. Its compact design makes it suitable not only for fixed high-voltage laboratories, but also for on-site testing tasks that require movement and transition.
4. Integrity of supporting equipment: The company provides supporting equipment including voltage regulating consoles, voltage dividers, and protective resistors, forming a complete power frequency withstand voltage testing system. This system has been designed for compatibility, aiming to help users achieve the entire testing process from voltage regulation, sampling to protection, and improve the coordination of the testing process.
