Profile: Eta-Com UK Preedcrete Ltd. provides a full range of betobar-r cast-resin insulated busway systems. The betobar-r system complies with all the requirements for current distribution at low and medium voltage. The busbar consists of copper or aluminum conductors, embedded in an enclosure of a difficult inflammable, self-extinguishing and homogeneous insulation mix based on epoxy cast-resin with mineral fillers ensuring high mechanical strength and chemical withstand. 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.
