enRR-CST is new silicone rubber cold shrink tube (built-in Rubber Ring) with special appearance. It’s specially designed to improve silicone cold shrink tube’s resistance to puncture and other external damage. It’s a kind of good accessory for weatherproofing protection on cable connections or joint, mostly applied on cell sites, such as connection between jumper cable and connector (7/16 DIN, N type or 4.3-10 connector) on RF equipment (RRU, Antenna and passive device), and joint between feeder and jumper cable. Comparing with tape sealing protection, time of installation is much shorter (15-30 seconds), more convenient, uniform waterproofing quality.
Applications
1. It is widely used for waterproof seal in coaxial cables on telecommunication base stations, N-type connector, 1/2 jumper, Din head and 1/2 jumper connector;
2.It can be used as a waterproof seal for cable television connector;
3. It can be used as a waterproof seal for connecting wires and cables;
4.Insulation seal for other types of connection;
