Cable accessories have evolved through three eras:
1.Early Era (Pre-1960s):
Oil-Paper Cables: Hand-wrapped taped joints; bulky porcelain terminations.
Limitations: Prone to leaks, partial discharges, and short lifespans.
2.Polymeric Revolution (1970s–1990s):
Heat-Shrink Tech: Polymer sleeves replaced tapes, improving sealing.
Cold-Shrink (1980s): Pre-expanded EPDM/rubber components enabled tool-free installation.
3.Modern Innovations (2000s–Present):
Pre-molded Accessories: Factory-tested silicone/EPDM systems with integrated stress control.
Smart Features: Embedded sensors for real-time temperature/PD monitoring.
