Abtech High Voltage Stainless Steel Junction Boxes For Hazardous Area Oil & Gas Projects

T&D working with Abtech have secured new orders from KCA Deutag Tender Barges Pte Ltd for high voltage, hazardous area junction boxes with Ex e certification.

Abtech VPJB custom-built junction box enclosures have been specified by T&D to provide 3.3kV high voltage power distribution on the KCA offshore jack-up rig in a Zone 2 (Class 1 Div 2) hazardous area. Abtech VPJB customised bespoke enclosures are designed around the Abtech SX range of stainless steel, high voltage, hazardous area junction box enclosuresAbtech

Pictured today ready for delivery : Abtech High Voltage Hazardous Area Certified Junction Box (T4 Temperature Rating, IP66, 1300A, Rated Up To 11kV, ATEX Ex e Certified, 346W Power Dissipation). The stainless steel enclosure side is pre-drilled with 11 side entries (5 x 63.5mm and 6 x 40.5mm) and glanded using ATEX Certified nickel plated brass cable glands (M40 and M63) to terminate the incoming wire braid armoured marine cables.

The Lead Electrical Engineer was very concerned about the ability of the existing type cable glands to effectively seal the incoming 3.3kV braided power cables in harsh, hazardous area environments as can be seen from the site photograph below. The Abtech VPJB enclosures will be installed as part of major power upgrade to the offshore rig and replace the existing enclosures which were condemned during a recent hazardous area inspection.

T&D recommended CMP Triton T3CDS Hazardous Area, Flameproof & Deluge Proof Cable Glands compatible with all types of armoured cable providing a flameproof seal on the cable inner bedding and an environmental seal on the cable outer sheath with IP68 rating. CMP Triton CDS Type T3CDS Cable Glands are Triple Certified for hazardous area installation : Flameproof (Type 'd'), Increased Safety (Type 'e') and Restricted Breathing (Type ‘nR’). CMP Triton brass cable glands are nickel-plated to provide excellent corrosion resistance required for long-term service operation in offshore environments and hazardous areas.

Abtech have customised the junction boxes to include pre-fitted CMP Triton cable glands to enable quick on-site cable termination of the 3.3kV power cables.
