VACEM's impressive range of electrical products includes vacuum interrupters, embedded poles, and more. Their vacuum interrupters are made of ceramics and boast a voltage range of 1.14kV to 40.5kV, current from 63A to 4000A, and a rated short circuit breaking current from 2kA to 40kA. These products comply with both national and international standards, including GB and IEC standards.
VACEM has undergone three large-scale technical transformations and has introduced advanced production processing equipment from Germany and the United States. As a result, they now have first-class technology equipment and perfect testing means. Their products are characterized by standardization, seriation, miniaturization, and specialization.
VACEM also has an experienced R&D team, a complete and mature R&D program, and a special department dedicated to organizing the development of new products. To stay ahead of industry technology trends, VACEM has established long-term cooperative relationships with other well-known companies.
