DC high-voltage generators play an indispensable role in power cable testing. This article will deeply explore the five major functions of DC high-voltage generators in cable testing, as well as their key position in ensuring cable quality and safety.

The DC high-voltage generator uses medium-frequency rectification and filtering technology to solve the shortcomings of large ripple coefficient and unstable waveform of the power frequency DC high-voltage generator. It is widely used in DC withstand voltage test and leakage current test of electrical equipment, and is specially equipped with the function of testing the voltage U1mA under 1mA and the leakage current under 0.75U1mA of the zinc oxide lightning arrester.

DC withstand voltage mainly test the insulation strength of the cable, is to check the oil and paper cable dry, bubbles, paper insulation in the mechanical damage and process wrapping defects in an effective method, DC leakage current test can be sensitive to reflect the cable insulation moisture and deterioration conditions.

With the continuous expansion of the market, our marketing department has recently reached an important shipment milestone: we have successfully exported 3 sets of equipment to international markets. The shipment includes 2 sets of DC High Voltage Generators, which will serve customers in the USA, and 1 set of Transformer DC Resistance Tester, which will be utilized in Vietnam.

Although the DC withstand voltage test and leakage current measurement methods are the same, their functions are different. The former is to test the insulation's dielectric strength, and its test voltage is higher; the latter is used to check the insulation condition, and the test voltage is relatively low.

Our American customer have placed three orders for DC high voltage generator all within recent three months. Now comes the third order.

Successful and continuous cooperation with American customers

Nigerian customers have reached a cooperation with Rui Du Mechanical and electrical to purchase a batch of RDYZ-302 Metal Oxide Surge Arrester Analyzer for total whole 7 sets from our company. Up to now, this batch of equipment has been produced and successfully sent to the port through quality control at different levels.

In June of this year, the performance of Rui Du Sales Department maintained a high-speed growth momentum, and good news was frequently reported. Compared with previous years, this month's sales have exceeded the record of previous years! Outbreaks are coming one after another. Under the background of overall economic contraction, it is not easy to achieve such achievements in the environment of increasing competition in the industry.
