Cold shrink cable accessories—pre-stretched elastomeric (silicone/EPDM) components that contract onto cables without heat—have become a dominant technology in medium- and high-voltage power networks. Since 3M pioneered the technology in the 1960s, the industry has evolved from niche to mainstream, driven by grid modernization, safety demands, and reliability requirements.
Aging resistance is one of the core performance indicators of cold shrink cable accessories, which directly determines their service life, operational reliability, and long-term stability in power systems.
