Tranberg have manufactured junction boxes for hazardous areas for the offshore installations in the North Sea since the beginning of the Norwegian oil history. Our strength is to develop junction boxes together with customers to meet the demands for flexibility and best solutions.

Stainless Steel Junction Boxes
All our junction boxes are produced in sheet metal, Stainless Steel AISI 316L, to meet the market for lighter weight and increased quality demands. The TEF 1058 and TEF 1059 series are used for a wide range of installations.

Junctionboxes for Electro, Instrument and Telecom
Typical solutions are for the Electro, Instrument and Telecom market, ESD’s and control stations i.e. They can be equipped with cable glands, terminals, pushbuttons and lamps, instruments, relays, fiber optical connections and patch panels, medium voltage connections up to 6,6kV etc.

Flexible enclosure system for RIO systems, switching and distribution panels, high voltage solutions
The series TEF 1060 is our most flexible enclosure system. The enclosures are often used for RIO systems, switching and distribution panels, high voltage solutions etc. Tranberg enclosure system TEF 1060 also includes solutions for encapsulating smaller EExd enclosures for Non-Ex components. Our solution is to use an aluminium EExd enclosure inside a TEF 1060 EExe Stainless Steel AISI 316L cabinet. This results in a very flexible and cost efficient solution.
