Get ready to experience the cutting-edge technology of VACEM's electrical products! Our main products include the highly sought-after vacuum interrupter and embedded pole. Our vacuum interrupter is made of top-quality ceramics and boasts a voltage range of 1.14kV to 40.5kV, current from 63A to 4000A, and rated short circuit breaking current from 2kA to 40kA.
At VACEM, we take pride in complying with relevant national and international standards (GB and IEC standards). We've undergone three large-scale technical transformations and have introduced advanced production processing equipment from Germany and the United States. As a result, we have first-class technology equipment and perfect testing means. Our products are characterized by standardization, seriation, miniaturization, and specialization.
We have an experienced R&D team and a complete, mature R&D program, as well as a special department dedicated to organizing the development of new products. To stay ahead of the curve and accurately grasp the development trend of industry technology, we establish long-term good relations of cooperation with other well-known companies.
