Heat shrink tubing is used as an insulating sleeve. What is the insulation performance of heat shrink tubing? When I use heat shrink tubing as an insulating sleeve, how do I determine whether it meets the insulation requirements of the product? Now follow the editor of DUWAI heat shrink tube manufacturer to unlock this little skill.

    The insulation level of heat shrinkable tubes is mainly distinguished by voltage, because the voltage of the conductor may often be different depending on the industry. At this time, our heat shrinkable tubes need to be subdivided to a certain extent so that the heat shrinkable tubes can also Distinguish based on voltage intensity.

    Heat shrinkable tubes are mainly divided into five insulation levels: 600V, 1KV, 10KV, 20KV, and 35KV.

    600V low-voltage insulating heat shrinkable tube is mainly used in the electronic field, and is often used for low-voltage wiring harnesses, cable protection and other purposes. Like the general electronics industry, they are all 24V, 36V, or at best 220V and 380V, so low-voltage heat shrinkable tubes can cover all use occasions.

1KV heat shrink tubing is often used for busbar docking protection and is widely used in low-voltage electrical cabinets. The operating voltage is between 600V and 1KV, which makes up for the insulating strength of 600V heat shrink tubing.

10KV, 20KV, and 35KV are high-voltage busbar heat shrinkable tubes. Which one to use depends on the voltage strength.

    The above 600V, 1KV, 10KV, 20KV, and 35KV refer to the rated voltage. If the long-term working voltage of the wire is 2KV, then you need to choose a 10KV heat shrinkable tube. If you use a 1KV heat shrinkable tube, there is a possibility of breakdown. , leaving electrical traces.

    The insulation grade of heat shrinkable tubes is closely related to the wall thickness and formula materials. When the materials are the same, wall thickness is one of the main factors that affects the insulation grade. The main materials of 1KV and 10KV are PE polyethylene. The 10KV heat shrinkable tube is much thicker than the 1KV heat shrinkable tube. The higher the withstand voltage level, the thicker the wall thickness.
