Abtech Busbar Box range of high voltage electrical enclosures enables 11kV cable terminations and cable connections up to 1000sqmm conductors. The intelligent design of the Abtech Busbar Box range allows high voltage cables to enter the electrical enclosure and to be terminated onto the busbar without having to be bent - quick and easy high voltage cable terminations (11kV) are thereby ensured in normally difficult cabling applications.

The 11kV enclosure has heavy duty machined hinges with lift off cover pad-lockable cover and is DTS-01 deluge tested.

Abtech Busbar Box high voltage (HV) cable junction boxes are manufactured from 316L stainless steel and used primarily for jointing cables or as a connection box, the Busbar Box is capable of connecting three phases plus neutral and up to six conductors per phase.
