Weatherproofing Cold Shrink Tube for 12-40mm Connection
Cold shrink tube is designed for weatherproofing protection on connections between jumper cable and connector (7-16 DIN, N type or 4.3-10) of wireless equipment, such as RRU, Antenna and Microwave. Comparing with tape sealing protection, cold shrink tube installation is much shorter (15-30 seconds), convenient installation, uniform appearance for acceptance.
Features
» High elastic silicone rubber tube structure with mastic built-in for better weatherproofing protection;
» Stable and long life during operation;
» Fast installation, only 15-30 seconds needed to seal one connection;
» Perfect SWR performance approved by telecom operators;
» Good operating capability under extreme cold and hot condition, anti-UV, anti-ozone;
» Much time and labor cost saving;
