The cold shrinkable tube of high ratio silicone rubber is made of special silicone rubber material, which has the advantages of large shrinkable ratio, excellent physical and mechanical properties and puncture resistance. It is suitable for waterproof and moisture-proof sealing of communication and cable TV connection joints, insulation sealing of wire and cable connection, insulation protection of other types of connectors, etc. The product is mainly used in the construction of 4G / 5G communication base station for sealing and waterproof protection of antenna feeder system.
Antenna and feeder system is one of the important parts of microwave relay communication. The antenna can transform the electromagnetic wave transmitted in the feeder into the electromagnetic wave transmitted in the free space or the electromagnetic wave transmitted in the free space into the electromagnetic wave transmitted in the feeder. The feeder is the transmission channel of electromagnetic wave. In the microwave relay communication circuit of multi-channel shared antenna and feeder system, the technical performance and quality index of antenna and feeder system directly affect the communication quality of each microwave channel of shared antenna and feeder system.
