BSM1 series copper conductor denselyinsulated Busway - Product

BSM1 busway system possesses the common characteristics of BSM compact insulation busway series; the differences are: its conductor adopts T2 quality copper. loading area of the selected is rather large (approximate the loading area of thetraditional air busway system),therefore the electric resistance is small; the rise of temperature is low, its power consumption is small.
