In especially 3G and LTE (4G) base station projects, the antenna outputs are very close to each other and it is almost impossible to make the isolation by electrical tapes. In order to be able to have perfect isolation, cold shrink tubes should be used in 3G and LTE base stations.
Wetra Cold Shrink Tube Techical Specifications
Wetra cold shrink tubes
Wetra cold shrink tubes are open-ended, tubular rubber sleeves that are factory expanded and assembled onto a removable core. Cold shrink tubes are supplied for field installation in this pre-stretched condition. The core of cold shrink tube is removed after the tube has been positioned for installation over an inline connection, terminal lug or other similar applications, allowing the tube to shrink and form a waterproof seal.
Wetra cold shrink tubes are cold applied. Cold shrink tube applications enable quicker, easier and safer isolation when compared to heat shrink tubes. Cold shrink tubes are also ideal solution where hot work permits are difficult to obtain.
Features of Wetra cold shrink tubes
