Tower-top remote radio units (RRU) are powered by 48 VDC supplied by the station battery, increasing the risk of damage to equipment within the building should lightning strike the tower, as some of the lightning current will enter the building via the 48 V supply cables.
Equipment may be damaged either by direct strikes to the tower, strikes to the power line or from indirect strikes caused by cloud-to-ground or cloud-to-cloud discharge. Transient electrical disturbances similar to lightning may be caused by power switching operations and power line faults.
The Novaris RRU2+2-125-65DC Lightning and Surge Protector has been developed specifically to match with RRUs located at the tops of towers, such as those used by 4G systems.
