Cold-Shrink Cable Accessories
Tool-free cold-shrink caps, joints and breakout boots for telecom and power cables.
Application Overview
Cold-shrink accessories wrap a silicone sleeve around a cable, then a removable spiral lets it contract to a permanent, uniform radial seal — no torch, no tape, no special training. We produce cold-shrink end caps, joints and breakout boots with pre-lubricated inner walls and validated long-term retention, for telecom feeders through medium-voltage power cables.
Technical Standards
- ✓IEC 60502 / IEEE 48 style medium-voltage accessory performance envelope (MV builds)
- ✓IEC 60529 IP68 sealing performance validated
- ✓Long-term radial retention force validated by accelerated aging
- ✓RoHS / REACH compliant; -50 °C installation rating
Manufacturing Process
Sleeves are extruded and vulcanized, expanded onto removable support spirals, and packaged in ready-to-install kits.
- Inner-wall lubrication integrated for fast sliding during installation
- Support spiral extraction force validated — must release without snagging
- MV builds integrated with stress-control geometries
- Kit packaging with installation steps printed per market language
