Cold Shrink Tube Silicone Rubber for Weather Proof
Cold Shrink Tube, also is known well as “Cold Shrink Wrap”, is manufactured with silicone rubber for weatherproofing protection on telecommunication equipment connections, 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
» Easy and quick installation
» Does not require any tools or heat
» Provides good thermal stability
» Accommodates a broad range of cable sizes
» Excellent tear resistant
» UV and ozone aging resistant
Note: In certain applications, a foam tape will be needed for smaller cable diameter that cannot be covered with the tube range, the foam tape is used to increase the smaller cable diameter and assure the sealing of clod shrink tube.
