Carrying high currents (transformer to switchboards, main distribution lines, power distribution for factories) using “Cast Resin Busbars” in outdoor environments, gallery transitions, chemical plants, harbour applications, tunnels instead of cables that are applied as mandatory offers many advantages. Aluminium housing covers the “DUROCOMP” composite material that is manufactured from specially selected pure silicium minerals and epoxy resin and has superior temperature and mechanical operation features and insulates the E-Line CCR Busbar from external elements.
