The Cembre 2811224 is a premium polyolefin heat shrink tubing designed to provide reliable electrical insulation, cable identification and long-lasting mechanical protection. Manufactured by Cembre, this TERMOBLOCK heat shrink sleeve is ideal for industrial wiring, control panels, automation systems and OEM electrical installations requiring dependable cable management.
Featuring a 2:1 shrink ratio, the tubing shrinks tightly around cables and electrical connections, providing excellent resistance to abrasion, moisture, chemicals and environmental contaminants. Its halogen-free, flame-retardant polyolefin construction delivers outstanding durability while maintaining flexibility for fast and professional installation.
With an internal diameter of 19.0 mm before shrinking, approximately 9.0 mm after shrinking, and supplied on a 5 m coil, the grey Cembre 2811224 is ideal for cable insulation, strain relief and wire identification across a wide range of industrial electrical applications.
Heat shrink tubing provides a durable insulating barrier around cables and electrical terminations while improving resistance to vibration, abrasion and environmental exposure. When heated, the tubing contracts tightly around the cable to create a neat, professional finish and extend the service life of electrical installations.
Cembre TERMOBLOCK tubing is trusted by electricians, panel builders and machine manufacturers for dependable cable insulation, wire identification and mechanical protection across demanding industrial environments.
