Waterproof cold shrink tube used for Antenna and RRU
Time: 2020-07-18 14:08:17     Copyfrom: SuZhou Volsun Electronics Technology Co.,Ltd.

In the 3G era, there were distributed base stations, and there were two things, BBU and RRU. The BBU is the base unit and the RRU is the RF part.


After 3G, in the 4G era, it is the configuration of the BBU+RRU+ antenna feeder. The only difference is that the RRU in the 3G era is basically wall-mounted indoors, and is also connected to the antenna through a feeder. But in the 4G era, RRU is basically on the tower, saving some money for feeder. The BBU and the RRU are connected by a long fiber. Only a short jumper is connected to the antenna from the RRU. However, if the RRU fails, it will have to be taken with the tower to the tower, and it also takes up the position on the tower.



Cold shrink tube is widely used for connector insulation and protection. The main application is in Antenna and RRU connector. The following picture can show you the detail application of our silicone cold shrink tube:





The silicone cold shrink tube reliably seals electrical connections of electric communications and cable televisions against water and moisture and effectively insulates wire and cable connections or joints and other electrical connections etc.For the cold shrink tube,we have full set of technical performance test report from SGS. Such as IP68 waterproof grade,UV resistant,Ozone Aging, High temperature resistant,Antimicrobial activity test report,etc.So our quality is guaranteed.
