ISO 9001:2015 Certification

SEECO is proud to announce that we are now ISO 9001:2015 certified. ISO 9001 is the world's most widely recognized quality management standard.

The ISO 9001:2015 certification awarded is for the entire SEECO organization, covering all SEECO facilities and all business functions. This recognition highlights our ongoing commitment to providing quality products and exceptional customer service.


SEECO continues to deliver innovative switch designs that improve performance and reliability. Our unitized transmission switches are fully assembled and adjusted on a tube or truss and include factory adjustment of the interphase pipe and associated levers, cranks, clevises, along with synchronous clocking of all three phases. Before shipment, unitized switches are operated and undergo rigorous factory acceptance testing to ensure optimal performance when installed. Factory unitizing reduces installation time and cost, reduces the possibility of field adjustment error, improves installed switch performance and reliability, and delivers the lowest long term, total cost of ownership.
