BTH

BTH is an initialism that may refer to several entities or concepts depending on the context. The most widely recognized use is British Thomson-Houston, a historic British electrical engineering company. The name also appears in other, context-specific uses.

British Thomson-Houston (BTH) was formed through an alliance between British engineers and the Thomson-Houston Electric Company of the United States. It produced electrical equipment for power generation, railway traction, and industrial automation, including traction motors, switchgear, transformers, and control systems. The company contributed to the development of railways and electrical infrastructure in Britain and beyond. In the mid-20th century, BTH became part of Associated Electrical Industries (AEI), and the BTH name was gradually phased out as the group restructured.

In other contexts, BTH may serve as an acronym for different organizations, terms, or place names. These usages are less standardized and highly dependent on the field, region, or language, so their meanings vary and are often clarified by surrounding text.
