Applications
- Repair of damaged cable jackets and insulation layers
- Protection of aerial power cables
- Repair of buried or ducted communication cables
- Restoration of polyethylene or metal cable sheaths
- Moisture sealing of cable contact connections
- Leak protection for pressurized and non-pressurized cables
- Maintenance and repair of telecom and power cable systems
Product Structure
The sleeve consists of a reinforced heat-shrinkable outer layer combined with a hot-melt adhesive inner layer. Fiberglass reinforcement significantly improves bursting strength and resistance to mechanical stress. A metal locking rail allows the sleeve to be wrapped around the cable before heat shrinking.

Installation Method
- Place the wraparound sleeve around the damaged cable section.
- Insert the metal locking rail and secure the sleeve edges.
- Apply heat evenly along the sleeve using an appropriate heat source.
- Allow the sleeve to shrink fully while adhesive flows to seal the cable.
- Ensure tight sealing at both ends of the sleeve.
