Products & Solutions

Our betobar-r busways consist of copper or aluminium conductors with more than 98% IACS electrical conductivity for Cu and 61% IACS electrical conductivity for Al. These are embedded in a vacuum mixed insulation of epoxy and selected inert materials of different grain sizes to make up Eta-com's "BIM-mix". This casting mix has high mechanical strength, excellent electrical specifications as well as outstanding physical characteristics. The betobar-r system is also impervious to moisture, as well as being highly fire resistant.

An extensive range of element shapes can be manufactured. This is due to the flexible production method used in universal casting moulds with an integrated processed casting method.

The prefabricated elements are self-supporting and the conductors are electrically connected by double fishplate junctions. These junctions contain an oversized contact surface to allow for minimum contact resistance and more flexibility during installation.

The junctions are overcast with "BIM-mix" overlapping element ends in order to obtain a homogenous water- and dust proof insulation over the entire length of the busway, thus ensuring high quality and reliability.
