Why Use 3M 77 Tape in Base Station
Some base stations are set up on top of buildings or other high constructions or terrains. It can run unattended for a long period. Today's base station equipment is mainly electrical products such as power cabinets, communications cabinets, battery pack, air conditioner, etc. They are interconnected by various cables, and these devices can run uninterrupted all year round. Thus, the chance of fire and electrical hazard is increased due to the extended work time. Since electrical fire can burn very fast, a small fire will cause a considerable damage to the base station. For base station sites susceptible to megathermal climate, we will need not only apply weatherproof measures, but also fireproof measures.
