11kV Enclosure – Offshore Umbilical Cables Termination Box

11kV Enclosure - Offshore Umbilical Cables Termination Box

HV Enclosures & Junction Boxes Up to 11kV

Abtech SX125 high voltage hazardous area electrical enclosures and junction boxes provide safe power distribution to connect up to 24 power conductors for 11kV systems – ATEX certified for Zone 1 and Zone 2 connection of HV cables in hazardous area locations and are based on the Abtech DPJB.

The 11kV enclosure is made from a marine grade stainless steel construction with an impact resistance of >10Nm.

Abtech SX125 high voltage (HV) cable junction boxes are manufactured from 316L stainless steel and provides a unique solution for the termination of offshore umbilical cables or onshore distribution systems.

A separate control compartment is used for terminating fibre optic or control cables. This allows the installer to work on optical fibres or control conductors without isolating HV supply
