Eta-com UK - Cast Resin Insulated Busbars

Cast Resin Insulated Busbars - Cast-Resin Bus Bars IP65 IP68.7

Eta-com UK Eta-com Betobar Logo

The ‘betobar-r’ busbar, produced in Belgium, consists of copper or aluminium conductors embedded in an enclosure of a non flammable, self-extinguishing and homogeneous insulation mix, based on epoxy cast-resin with mineral fillers, ensuring high mechanical strength and chemical withstand. Standard types are available for current ratings + 6300A and voltage ratings up to 17.5kV. Systems for higher current ratings or DC applications are possible on request.

The busbar line consists of a number of prefabricated elements. The electrical jointing of the conductors is achieved by means of double fish plates and high tensile steel bolts. The junctions and the element ends are overcast with the same insulation mix as used for the elements. In this way, an integral insulating enclosure IP66/IP68 is guaranteed over the full length of the busbar run. Straight junctions and elbow junctions are available, each facilitating installation adjustments of 0-20mm per standard junction.

Element Shapes

The ‘betobar-r’ busbar system is available in a wide range of standard element shapes, forms and lengths fabricated to suit the typical project requirements:

  • Straight elements
  • Elbow elements, horizontal & vertical
  • Z (double elbow) & T elements
  • Flanged terminal elements
  • Tap-off facilities & phase-transfer elements
  • Thermal expansion compensation elements
  • Tailor-made terminal elements for transformer, generator or switchboard connection

Characteristics

The most important advantages of the ‘betobar-r’ system are:

  • High short-circuit withstand
