High voltage enclosures for hazardous environments

A-Block medium voltage enclosure

A range of medium and high voltage enclosures has been released for use in offshore and Arctic environmental conditions.

R Stahl, a manufacturer of safety equipment for hazardous areas, has launched a comprehensive range of Ex High Voltage Systems for Zone 1 and Zone 2 hazardous areas, as well as for safe areas.

The new range of medium and high voltage connecting systems is one of the largest ranges currently available globally from a single source. The range includes Tranberg A-Block medium voltage (MV) enclosures, high voltage busbar enclosures (up to 36kV), topside umbilical termination units, cable junction boxes, plug-in connectors and cable cleats. These systems are available as standard products or can be custom-engineered to suit specific customer requirements. Typical applications include power distribution for subsea applications, hazardous areas in offshore and onshore oil and gas installations, high voltage solutions, Arctic installations and saline atmospheres.

The Tranberg TEF 1060 A-Block range of medium voltage enclosures are manufactured to IEC60079 and certified to ATEX and IECEx standards. These flexible, compact, stainless steel enclosures are suitable for use in Zone 1, Zone 2 and safe areas and are available up to 11kV (as standard) and are suitable for DC systems. The A-Block product can be used with current loads of up to 100A.

The Tranberg TEF 1060 Busbar system is also available for use in Zone 1, Zone 2 and safe areas. These ATEX and IECEx-certified high voltage enclosures are available up to 11kV in three different designs: rectangular, curved and G-profile. These high voltage enclosures use tinned copper busbars combined with Ex-certified isolators.

The SHDSS (Sapphire) range of cable cleats are metallic cable cleats that are designed, manufactured and tested in accordance with the International Standard ‘cable cleats for Electrical Installations’ IEC61914:2009. The 316L stainless steel cable cleats are designed for high short circuit conditions on cables held in single and parallel/flat formation to ensure cable retention without damage. Combined single (M12) and two-bolt (M10) fixing designs are available. Low Smoke and Fume (LSF) liners are supplied as standard, helping to restrain the cables within vertical applications, providing a layer of protection between the cable sheath and the cable cleat during normal operation where thermal elongation of cable occurs. This protects the cable from chafing on any mounting surface due to differential movements such as those found in marine and offshore installations.
