The core function of insulation tape is to achieve electrical insulation, joint sealing and protective fixing. The core principle of selection is "voltage matching, scenario adaptation and safety compliance". LVZHIMEI insulation tape covers two series: polyvinyl chloride (PVC) and polyolefin, which can fully meet various needs of low-voltage electrical operations below 380V, and has passed national electrical product safety certification to ensure use safety. As a conventional industrial product, LVZHIMEI has optimized and upgraded the formula of PVC insulation tape. It uses high-strength PVC film as the base material, coated with high-quality rubber pressure-sensitive adhesive, and has good insulation (insulation resistance ≥10¹²Ω), flexibility and bonding strength, not easy to crack or degum. It is suitable for conventional scenarios such as indoor wire wrapping, joint sealing and local insulation of electrical equipment, with high cost performance, and is the preferred product for electricians' daily operations.
Polyolefin insulation tape is developed for special environmental scenarios, with better weather resistance, chemical corrosion resistance and waterproof performance, and can adapt to harsh working conditions such as humidity, high temperature and outdoor. In humid environments (such as kitchens, bathrooms, underground projects), LVZHIMEI polyolefin insulation tape has good waterproof and sealing performance, which can effectively prevent insulation failure caused by moisture penetration and ensure electricity safety; in high-temperature environments (such as motor rooms, boiler rooms), this tape can withstand long-term high temperature of 80℃, with stable insulation performance and no softening or deformation; in outdoor scenarios (such as overhead lines, outdoor distribution boxes), its UV aging resistance is excellent. After 5000 hours of UV aging test, the bonding strength and insulation performance still remain above 80%, and the service life is far longer than that of PVC insulation tape.
When selecting products, the insulation strength should first be determined according to the voltage level. LVZHIMEI PVC insulation tape is suitable for 220V household circuits and 380V industrial low-voltage circuits, while polyolefin insulation tape can be adapted to various low-voltage scenarios below 380V and is more suitable for special environments. At the same time, it is necessary to accurately judge according to the characteristics of the construction environment: waterproof polyolefin insulation tape is preferred for humid environments, high-temperature resistant insulation tape can be used in high-temperature environments, and polyolefin products resistant to UV aging must be selected for outdoor scenarios. In addition, LVZHIMEI reminds users that standardized construction is the key to ensuring insulation effect. Before construction, clean the wire surface with a dry cloth to ensure no oil or dust; when wrapping, overlap half the width, wind tightly without bubbles or gaps; wrap 2-3 more turns at the joint to enhance sealing protection. For important electrical equipment, it is recommended to regularly check the status of insulation tape and replace aging and damaged products in a timely manner to avoid electrical safety risks from the source.
