The Cembre 2811197 is a premium polyolefin heat shrink tubing designed to provide dependable electrical insulation, cable identification and long-lasting mechanical protection. Manufactured by Cembre, this TERMOBLOCK heat shrink sleeve is ideal for industrial wiring, electrical control panels, automation equipment and OEM installations requiring professional cable management.
Featuring a 2:1 shrink ratio, the tubing shrinks securely around cables and electrical connections, protecting them against abrasion, moisture, dust and corrosive environmental conditions. Its halogen-free, flame-retardant polyolefin construction delivers outstanding durability while remaining flexible for fast and reliable installation.
With an internal diameter of 12.5 mm before shrinking, approximately 6.0 mm after shrinking, and supplied on a convenient 10 m coil, the Cembre 2811197 is an excellent solution for cable insulation, strain relief and colour-coded identification in demanding electrical applications.
Heat shrink tubing provides a durable insulating barrier around cables and electrical connections while improving resistance to wear, vibration and environmental exposure. When heated, the tubing contracts tightly around the cable to create a neat, professional finish that helps extend the service life of electrical installations.
Cembre TERMOBLOCK tubing is trusted by electricians, machine builders and panel manufacturers for dependable cable protection in demanding industrial environments.
