45kV Enclosure – HV High Voltage Junction Box Zone 1 Hazardous Area

Product Overview

Abtech 4TJB high voltage hazardous area electrical enclosures and junction boxes provide safe power distribution up to 45kV systems up to 1000sqmm cables – ATEX certified for Zone 1 and Zone 2 connection of HV cables in hazardous area locations.

The Abtech 4TJB can accept three phase connections either straight through or bottom entry only. The 45kV enclosure has heavy duty machined hinges with lift off cover pad-lockable cover and is DTS-01 deluge tested.

Abtech 4TJB high voltage (HV) cable junction boxes are manufactured from 316L stainless steel and used primarily for jointing cables or as a connection box, the 4TJB is capable of connecting three phases straight through or bottom entry only and one conductor per phase in and out.

Abtech 4TJB
