Up to now, many wire joints or repairs have used electrical insulating tape for insulation protection. However, it will face the problem of aging and loosening. The degradation of the adhesive performance will lead to the insulation protection not meeting the requirements and safety accidents. Because the insulating tape is wrapped in circles, the integration is poor, and the process is complicated. If there are sometimes many wires, wrapping the tape will be troublesome. Let's follow the editor of DUWAI to see whether heat shrink tubes can replace insulating tape? What are the advantages of each?

Advantages of heat shrink tubing

1. Since the heat shrink tube is integrated, it can be cut as long as needed, which makes up for the gaps between the insulation tapes during the winding process, prevents them from loosening and falling off, and improves safety.

2. The insulation of heat shrinkable tubes is more excellent. The insulation voltage of ordinary heat shrinkable tubes can reach 600V for a long time, and the withstand voltage can reach 2500V. It does not break down in 1 minute, which can prevent breakdown caused by short circuit.

3. The heat shrinkable tube has complete specifications, and various inner diameters are suitable for various cables.

4. The heat-shrinkable tube will stick closely to each wire after being heated. The resulting joint will have better sealing performance, insulation performance and wear resistance than the insulating tape.

5. Although insulating tape only needs to be wound by hand, its performance in all aspects is not as good as that of heat shrinkable tubes. Electrical insulating tape will be affected by the ambient temperature and will easily lose its stickiness over time, causing it to loosen and fall off. The use of heat shrink tubing will make the appearance more beautiful and smooth, while the insulation tape will always have lines when wrapped, which affects the appearance.

Advantages of electrical insulation tape

1. Without cutting the cable, the advantages of electrical insulation tape will be more obvious. By directly wrapping the electrical insulation tape around the wire, you can complete the insulation of the conductor and the repair of the wire.

2. The compatibility of electrical tape is very strong. No matter how thick or thin the wire is, it can be wrapped with one specification of electrical tape. However, the heat shrink tube needs to be purchased according to the outer diameter of the wire. The heat shrink tube of the corresponding specification can be used. For small amounts of wire repair, electrical insulation tape is more appropriate.

    After the above, the advantages of heat shrink tubing are obvious. The insulation, integrity, and sealing properties are better than those of insulating tape. The wear resistance and waterproofing of heat shrink tubing cannot be replaced by insulating tape. However, the advantage of insulating tape is that it can quickly repair wires. Each has its own advantages, and they are reasonable if they exist. Choose whether to use heat shrink tubing or electrical tape based on the actual application. It can be concluded that heat shrink tube can replace insulating tape to achieve insulation function, but it cannot be completely replaced in terms of convenience and compatibility. If you need to enhance the sealing, you can use adhesive heat shrink tubing, which can effectively prevent dust and water vapor from contacting the conductor.
