Betobar busbars have been developed as a modern, all-purpose means of efficient and safe transmission of electrical energy. They have been in manufacture for more than thirty-five years. This system complies with all the requirements for current distribution at low and medium voltage.The busbar consists of copper or aluminium conductors, embedded in an enclosure of a fire retardant, 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 up to 5000 A 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 joining 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 to IP68.IK10 is guaranteed over the full length of the busbar run. Straight junctions and also elbow junctions are available each facilitating installation adjustments of 10-20 mm per standard junction.
