Siemens has agreed to acquire California-based Trayer Engineering Corporation a prominent firm in the design and manufacturing of medium voltage secondary distribution switchgear suitable for outdoor and below ground applications. Trayer specialises in hermetically sealed padmount and submersible switchgear, specialised to be resistant to extreme weather conditions. The company is expected to provide complementary technologies to the Electrification and Automation Business Unit at Siemens, and to further support the market trend of undergrounding overhead electrical networks, to increase the resilience of North American distribution grids. Siemens intends to increase the availability of Trayer’s leading submersible and padmount switchgear portfolio via its own widespread presence in the market.

“We see a significant growth opportunity in secondary power distribution, particularly in addressing the challenges posed by extreme weather conditions. By combining forces, we will provide an end-to-end portfolio to our customers by unlocking resources and competencies to serve this growing demand,” said Stephan May, CEO of Electrification and Automation at Siemens Smart Infrastructure. “Our digital offerings and Siemens Xcelerator portfolio, Electrification X, complements Trayer’s resilient solutions to enable utilities and municipalities to upgrade their distribution grids and drive grid efficiency for outdoor and below ground applications.” 


Trayer has a long history in the production of maintenance-free switchgear of high quality, designed to meet the most challenging circumstances, such as areas prone to flooding or extreme weather conditions.
Trayer was founded as a family business in 1962 and will continue to operate as a separate legal entity, under the banner ‘A Siemens Business’. The transaction is subject to regulatory approval, and closing is expected to take place during this calendar year. The terms of the transaction have not been disclosed.
