The 230 volts AC cable developed by HUBER+SUHNER is a one-to-one replacement of the 48 volts DC cable in terms of function- ing but provides the customer with a solution that reduces power loss along the cable and can be more than 50 % lighter in weight. Avoiding CO2 emissions With a cell site of six remote radio heads with 1 200 W power consumption each, With many servic- es and applica- tions in demand, 5G will need a higher pow- er consumption of up to 1 500 W per RRH. This is a large increase in com- a cable length of 60 m and cross-sections of 10 mm2 per copper wire, the maximum energy loss of a 48 volts DC installation is 11.17 MWh per year, compared to a maxi- mum loss of 2.23 MWh of a 230 volts AC installation. Avoiding of 8.94 MWh corre- sponds to some 5 tons less CO2 per year. parison to the third and fourth generations, which typically needed around 300–500 W. Cable power dissipation from the line was recorded up to around 18 % for the 48 volts DC cable, whereas around 4 % of power was lost when testing the 230 volts AC solution. This saves the customer operating cost and avoids unnecessary CO2 emissions. brid High Voltage e system for RRH he capability to mast, the system ng with significant HUBER+SUHNER Sustainability report 2020Seite 31Seite 33
