What is the installation process for this tubing?
Position the assembly on the cable before making connections, ensuring a clean cable insulation of at least 5cm. After connecting, slide the tubing over the lug and unwind the core while gently pulling the loose tab. Once positioned correctly, the installation is complete.
How does the cold shrink design offer an advantage over heat shrink options?
Cold shrink tubing does not require heat during installation, allowing for quicker and safer application, especially in environments where heat could damage other components.
What material is used in the construction of the tubing?
The tubing is constructed from EPDM rubber, which offers excellent flexibility and resistance to high temperatures, ensuring long-lasting performance in various application scenarios.
Can it be reused or repositioned after installation?
Once installed, the cold shrink tubing should not be repositioned. However, if removal is necessary, it can be cut away, but replacement will be required as the material does not allow for reapplication.
