The ultra-low frequency high-voltage generator is a high-voltage test device for ultra-low frequency AC withstand voltage test. This device is suitable for electric power departments and industrial and mining enterprises to conduct insulation withstand voltage tests on polyethylene, cross-linked polyethylene plastic cables and other high-voltage electrical equipment on site. This device is less destructive than the DC withstand voltage test and is equivalent to the AC power frequency withstand voltage.
Many years of theory and practice at home and abroad have proved that replacing the power frequency withstand voltage test with a 0.1Hz ultra-low frequency withstand voltage test can not only have the same effect, but also the size of the equipment is greatly reduced, the weight is lighter, and the theoretical capacity is one-fifth of the power frequency set, and the operation is simple. Compared with the power frequency test, it has more advantages. This is why this method is commonly used in developed countries.
The ultra-low frequency produced by Huayi continues to attract foreign buyers for frequent consultation with high-quality test performance, competitive price advantage, and professional technical support. Recently, it has just provided a VLF 80KV ultra-low frequency withstand voltage tester for Vietnamese customers. Used to test the withstand voltage of 35kV and below XLPE insulated power cables. While we provide high-performance products, we also provide customers with high-quality after-sales service, we are ensure your satisfaction.
