RVV and BVR whether GM, what difference does it make?
General is not common, because of the big difference in structure;
RVV series sheathed multiple cord, rated voltage 300/500V, suitable for mobile laying;
BVR series insulated wire, rated voltage is 450/750V, when suitable fixed wiring need soft area. Under special circumstances, multiple BVR lines merge or replace the RVV;
RVV when BVR uses, even if the whole section to meet the requirements, but high costs and poor economy.
