In-Depth Analysis of Aging and Cracking in Soft Sleeves for Electrical Terminals

2026,01,23
Soft protective sleeves used on electrical terminals are prone to aging and cracking when exposed to harsh environments such as high temperatures, humidity, or ultraviolet radiation. This is mainly caused by material quality issues and external environmental factors. For example, elevated temperatures can reduce the plasticity of the sleeve material, leading to embrittlement, while UV exposure accelerates surface oxidation. In addition, continuous mechanical vibration and fluctuations in electrical load may damage the internal molecular structure of the soft sleeve.

Common signs of aging include color fading, surface cracking, and reduced flexibility. These issues not only compromise the stability of electrical connections but may also result in equipment malfunctions or safety hazards. Therefore, an in-depth analysis of the causes of aging and cracking in soft sleeves helps enable effective countermeasures and fundamentally improves the durability of electrical equipment.
