Surface Material for Substation Ground Grid

Oct 30, 2008· Surface Material for Substation Ground Grid Bilegan (Electrical) , I have seen some extreme cases where it was not possible to achieve an acceptable value using crushed stone so entire substations were paved with asphalt It is a somewhat rare case and definitely a more expensive option, but in a few cases maybe the one of the only ways to ....

What is the R

So let's keep in mind that while the R-value of two feet of soil outside of a building wall, say, may be between R 0135 and R 05, that 24" of dirt has much greater thermal mass than the same quantity (in equivalent R-value) of an insulating material such as fiberglass or solid foam insulation...
