Get ready to be electrified by VACEM's top-notch electrical products! Our main products include the incredible vacuum interrupter and the embedded pole, among others. Our vacuum interrupter is made of ceramics and boasts a voltage range of 1.14kV to 40.5kV, a current range of 63A to 4000A, and a rated short circuit breaking current of 2kA to 40kA. Plus, all of our products comply with relevant national and international standards, such as GB and IEC standards. VI is mainly applied to VCKJ5-1250A/1.14kV vertical LV AC vacuum contactor. Meets or exceeds the requirement of IEC60947-4 and GB/T14048-2001.
But that's not all! VACEM has undergone three large-scale technical transformations and has introduced advanced production processing equipment from Germany and the United States. As a result, we have first-class technology equipment and perfect testing means, and our products are characterized by standardization, seriation, miniaturization, and specialization. We also have an experienced R&D team, a complete and mature R&D program, and a special department dedicated to organizing the development of new products.
