Applications
-
Wire and Cable Insulation: Ideal for providing robust insulation and strain relief for large-diameter electrical wires and cables, especially in environments exposed to moisture.
-
Connector Protection: Ensures watertight sealing for large connectors, safeguarding them from environmental damage such as moisture, dust, and corrosion.
-
Mechanical Protection: Offers a strong barrier against abrasion, chemicals, and physical impacts.

Bundling: Suitable for bundling multiple cables together, providing a neat and professional appearance.
Example Installation Scenario
Consider an installer working on a marine electrical system where robust insulation and protection are crucial for large-diameter cables. By using the Thermosleeve CBDWT3X3/4BK4, the installer can cut the tubing to the desired length, slide it over the cables and connectors, and apply heat with a heat gun. The tubing shrinks to form a tight, secure fit, and the adhesive melts to create a watertight seal. This ensures long-term protection for the cables against water ingress, mechanical stress, and other environmental factors, which is essential for marine applications.
