The Cembre 2811201 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 panels, automation systems and OEM installations where reliable cable management is essential.
Featuring a 2:1 shrink ratio, the tubing shrinks tightly around cables and electrical connections, protecting them against abrasion, moisture, dust and environmental contaminants. Its halogen-free, flame-retardant polyolefin construction provides excellent durability while remaining flexible for quick and professional installation.
With an internal diameter of 25.4 mm before shrinking, approximately 12.7 mm after shrinking, and supplied on a 5 m coil, the Cembre 2811201 is ideal for cable insulation, strain relief and colour-coded identification in demanding electrical applications.
Heat shrink tubing creates a durable insulating barrier around cables and electrical terminations while improving resistance to wear, vibration and environmental exposure. Once heated, the tubing contracts tightly around the cable to provide a neat, professional finish and long-term protection.
Cembre TERMOBLOCK tubing is trusted by electricians, panel builders and machine manufacturers for dependable cable insulation across industrial automation, electrical distribution and OEM production environments.
