11kV Enclosure – Hv High Voltage Junction Box Zone 1 & Zone 2 Hazardous Area ATEX

High Voltage Junction Box 33kV-45kV - Zone 1 Zone 2 Hazardous Area ATEX

HV Enclosures & Junction Boxes Up to 45kV

Abtech HVJB high voltage hazardous area electrical enclosures and junction boxes provide safe power distribution for 11kV systems up to 1000sqmm cables offering flexibility over the choice of cables, entries and cable terminations – ATEX certified for Zone 1 and Zone 2 connection of HV cables in hazardous area locations.

11kV enclosure is suitable for low temperature applications and is DTS deluge tested.

Abtech HVJB high voltage (HV) cable junction boxes are manufactured from 316L stainless steel with a silicon gasket and stainless steel fasteners. The enclosure also features heavy duty machined hinges with lift off cover pad-lockable cover and has an orbital finish but painted and electro-polished options also available.

* (x‐x) demotes the number of connectors per phase, 1st position = top, 2nd position = bottom. For example: HVJB73(2‐1) = 2 x conductors per phase top entry and 1 x conductor per phase bottom entry. ** Power rating is determined by ambient temp range: ‐20 to +400C / ‐50 to +550C respectively. The higher power rating can also be achieved if the enclosure is marked Ex e IIC T1500C Gb. *** For cables greater then 300mm2, it is advisable to use the HVJB8 size enclosure.
