The H-J Family of Companies, a leading supplier of Transformer and Switchgear Components worldwide, has continued its policy of using the latest technology in its production and manufacturing processes. As a leading manufacturer in this segment, H-J has taken the next step in its extensive customer support program with the development of an independent high voltage test laboratory. This laboratory allows H-J to stay on the vanguard of its industry and further advance its product offerings through high quality research and development.
H-J can now provide test services for its entire spectrum of customers, including Utilities, OEM’s, Repair Shops, Universities and others.
The laboratory is located in St. Louis, Missouri, adjacent to the Company’s manufacturing facilities. The floor space of the lab is 100’ X 100’ feet with a ceiling-to-floor clearance of 50 feet, thus accommodating small to large sized equipment.
Acknowledging that safety is the most important factor, the new laboratory includes extensive safeguards as well as the presence of highly qualified personnel, carefully developed systematic procedures, visual and audible safety systems and access controls to all test areas.
H-J has the ability to conduct testing in accordance with all applicable standards including: ANSI/IEEE, NEMA, CSA and IEC. Tests can also be performed according to customer specific requirements.
H-J’s commitment to always provide better products and broader support to its customers continues with the addition of this laboratory. It clearly represents just one more value added service in its continued commitment to provide “Quality Products of International Reputation.”
