Get ready to experience the power of VACEM's top-of-the-line electrical products! Our main products include the highly sought-after vacuum interrupter and embedded pole, both of which are designed to meet the highest standards of quality and performance. Our vacuum interrupter is made of top-grade 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. VI is mainly applied to VCKG3/VJCZ5 and VCZG1-7.2 series MV AC vacuum contactor. Meets or exceeds the requirement of IEC62271-100 and E2 level in GB1984-2003.
At VACEM, we take pride in complying with relevant national and international standards, including 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, and our products are characterized by standardization, seriation, miniaturization, and specialization.
Our experienced R&D team and complete, mature R&D program ensure that we stay ahead of the curve when it comes to industry technology. We even have a special department dedicated to organizing the development of new products. To accurately grasp the development trend of industry technology, we establish long-term good relations of cooperation with other well-known companies.
