Installation Tips and Best Practices for Cold Shrinkable Tubes

A type of connector that is commonly used to insulate cables and electrical components is cold shrinkable tubes. These shrinkable tubes are handy when safeguarding electrical wires and components from weather elements. Choosing top-quality customize cold shrink tube is not an easy matter, and you need to have sufficient knowledge about the various features of these shrinkable tubes. In this blog, we will take a detailed look at multiple factors in selecting shrinkable tubes of a robust quality and the technique to install them properly. 

Installing Cold Shrink Tubing: A Step-by-Step Procedure

Step1: Clean the Surface

Before applying the cold shrink tube, the object's surface is free from dirt and liquid like water, oil, and grease. Use a suitable solvent or cleaning agent to remove any residue that may restrict adhesion.

 Step 2: Position the Cold Shrink Tube to Face the Correct Direction

Adjust the placement of the cold shrink tubing so that the rip cord should pass through the tubing from top to bottom. This rip cod is meant to be pulled during installation. 

Step 2: Cover the Cable with a Cold Shrink tube

Make sure to select the appropriate size of shrink tube is selected. Insert the cable and pass it through the cold shrink, but do not tighten the shrink tubing. 

Step 3: Tighten the Cable Firmly in a Fixed place

Attach the cable and tighten the ends of the cable with a wrench. The cold shrink should then be installed once the cable is tightened.

Step 4: Push the loose, cold shrink tube up to cover the tightened cable connection 

 The shrink tube should be moved upwards to surround the cable connection. 

Ensure the tubing remains in this position until you pull the rip cord. 

Step 5: Slowly Pull the rip cord

Once the rip cod is pulled, the plastic core will slip away from the tightened cable connection end, and the cold shrink will replace the plastic core. Once the plastic core slips away further in those spots, the shrink tube wraps around. 

Step 6: Keep Pulling the Rip Cord

Continue pulling the rip cord until the plastic core reaches the end of the cable. In this way, the shrink tube will completely cover the cable. 

Step 7: Installation Complete

Just discard the plastic core once the shrink tube has covered the cable. Check the cold shrink tube for gaps, tears, or incomplete sealing that does not adhere. Ensure that the tube has formed a tight and uniform seal around the application area, providing reliable insulation and protection against moisture and contaminants.

Conclusion

Selecting the appropriate cold shrinkable tube for your intended use requires thoroughly assessing various elements. This includes identifying your application's specific needs and considering factors such as size, material characteristics, and technical specifications, all of which influence performance and durability.

Moreover, when dealing with separable connectors, ensuring compatibility is crucial. It is essential to confirm that the chosen cold shrinkable tube is expressly designed to seamlessly integrate with these connectors, thereby establishing a dependable and secure connection. By adhering to this comprehensive approach and carefully considering the distinct requirements of your application, you can confidently procure a cold shrinkable tube that satisfies your demands and enhances the long-term reliability and effectiveness of your electrical or industrial setups.
