At this year's World Internet Conference, 5G was repeatedly mentioned. 5G telemedicine, 5G human-computer interaction, 5G rescue, 5G VR video and other applications were displayed one by one. The three major operators all focused on the experience of using the 5G communication network. The common fiberglass radome is widely used in 5G communication infrastructure. Traditional base stations are bulky and tall iron towers. 5G base stations are relatively small in size and can be aesthetically pleasing and diverse. Compared with traditional tall iron tower base stations, these small base stations can be made of fiberglass. The shell of this small base station is similar to an electrical cabinet. It is placed outdoors and needs to withstand wind, rain, and low temperature sunlight. The fiberglass radome can meet these weather resistance requirements.
Fiberglass radome has the following advantages
1. Non-metallic materials are not sensitive to electric shock, and are suitable for areas with more lightning and rainy climates;
2. The optical cable using FRP reinforced core can be installed next to the power line and power supply unit, and will not be interfered by the induced current generated by the power line or power supply unit;
3. Compared with the metal core, GFRP/KFRP will not produce gas due to the chemical reaction between metal and ointment, which will affect the optical fiber transmission index;
4. Compared with the metal core, FRP has the advantages of high tensile strength, light weight, bulletproof, anti-bite and anti-ant.
Applications in communication
Most of the towering communication towers are steel structures, but corrosion is a big problem, and fiberglass radome can solve this problem. The fiberglass cable tray is relatively light, and each independent part of the tower structure can be assembled quickly, and it is easy to install during the assembly process, which also reduces the weight of the entire tower body.
