Description

Technical Field

[0001] This utility model belongs to the field of rubber thread technology, specifically relating to a rubber thread with wear-resistant and moisture-proof functions. Background Technology

[0002] Rubber-insulated wires, a common type of electrical cable, are widely used in electrical equipment, household appliances, and industrial fields. However, in humid environments, especially in the humid climate of southern my country, phenomena such as the "return of spring" (a period of high humidity) frequently occur, resulting in extremely high air humidity and persistently damp ground. When rubber-insulated wires are used on the ground, their outer surface is in prolonged contact with the damp ground, causing liquid to gradually penetrate into the wire's interior. This penetration significantly reduces the wire's insulation performance, increases the risk of leakage, and in severe cases, may lead to short circuits, fires, and other safety accidents. To improve the moisture resistance of rubber-insulated wires, existing technologies typically use a thicker outer rubber layer. However, this method has significant drawbacks: First, thickening the rubber layer increases the wire's weight, increasing the difficulty of transportation and installation and limiting its application in weight-sensitive scenarios. Second, thickening the rubber layer hinders heat dissipation during operation, leading to heat accumulation and potentially causing the wire to overheat, thus affecting its electrical performance and lifespan. Therefore, existing technologies suffer from the problem of increased wire weight and reduced heat dissipation performance due to thickening the rubber layer. Utility Model Content
