Abstract
Description
Technical Field
[0001] This utility model belongs to the field of insulated wire technology, and in particular relates to polyvinyl chloride insulated wires. Background Technology
[0002] Polyvinyl chloride (PVC) insulated wires are wires made of metals such as copper or aluminum as conductors, with an outer layer tightly wrapped with PVC insulation material. The PVC insulation layer has good insulation properties, which can effectively prevent current leakage and ensure electrical safety. It also has good chemical corrosion resistance and is suitable for various environmental conditions. Due to its comprehensive performance advantages, this type of wire is widely used in many fields such as construction, industry, and household appliances, and is one of the essential basic components of modern electrical systems.
[0003] Existing PVC insulated wires have some drawbacks. The surface of the insulation layer of PVC insulated wires is relatively fragile. In scenarios involving frequent friction with other objects, wear, scratches, and even damage can easily occur. This not only affects the appearance of the wire but also reduces its insulation performance, leading to safety hazards such as leakage. When PVC insulated wires are exposed to the natural environment for a long time, their molecular structure will be gradually destroyed by continuous ultraviolet radiation, causing the insulation layer to age, discolor, harden, and become brittle. This severely reduces flexibility and insulation effect, shortens the service life of the wire, and limits its long-term stable use in harsh outdoor environments.
[0004] To address these issues, we offer PVC insulated wires. Utility Model Content
