■ Product Overview

The high‑voltage withstand test of electrical equipment is one of the most important tests specified in the “Insulation Preventive Test” standard. Withstand tests are classified into AC withstand tests and DC withstand tests; AC withstand tests, in turn, can be further divided into power‑frequency, variable‑frequency, and… 0.1Hz Ultra-low-frequency testing technology, wherein 0.1Hz Ultra-low-frequency technology is the latest advancement and is currently recommended by the International Electrotechnical Commission. The new generation… NDBLF Series microcomputer-based 0.1Hz The ultra‑low‑frequency high‑voltage generator is a core product independently developed by our company. It overcomes many of the shortcomings of first‑generation mechanical models and offers a significantly higher cost‑performance ratio than comparable imported products, making it particularly well suited for electrical equipment with large equivalent insulation capacitances. ( For example : Power cables, power capacitors, large and medium-sized generators, and electric motors, among others. ) Withstand voltage test, NDBLF The series of ultra-low-frequency high-voltage generators complies with 2004 The state has recently promulgated the power industry standard “General Technical Requirements for Ultra-Low Frequency High-Voltage Generators.” DL/T849.4-2004 》Requirements.
