2811511 Cembre TCS381X50Y/G TERMOCOIL
Cembre TCS381X50Y/G 2:1 halogen-free polyolefin heat shrink tubing supplied in a 50 m yellow/green coil for cable insulation, protection and protective earth identification.
Why Choose the Cembre 2811511 TCS381X50Y/G Heat Shrink Tubing?
The Cembre 2811511 (TCS381X50Y/G) is a premium 2:1 heat shrink tubing designed to provide dependable electrical insulation, mechanical protection and protective earth cable identification for professional electrical installations. Manufactured from durable halogen-free flame-retardant polyolefin, it is ideal for industrial control panels, switchgear, machinery, cable harnesses and OEM applications.
Designed for demanding industrial environments, this heat shrink tubing delivers excellent dielectric strength together with outstanding resistance to abrasion, moisture and chemicals. Its low shrink temperature enables rapid installation while creating a secure protective covering around cables, terminals and electrical connections for long-lasting reliability.
Supplied as a 50 m yellow/green coil, the TCS381X50Y/G is specifically intended for protective earth (PE) conductor identification while providing reliable insulation and cable protection. The tubing complies with recognised international standards including UL 224, IEC 243 and RoHS.

Reliable Cable Protection for Professional Installations
Heat shrink tubing provides durable electrical insulation while protecting conductors against abrasion, moisture, contaminants and mechanical damage. Once heated, the tubing contracts uniformly around cables and connectors to create a secure insulating barrier that improves reliability and extends service life.
The yellow/green colouring provides immediate identification of protective earth conductors, making the tubing particularly suitable for industrial control systems, switchgear, distribution equipment and electrical installations where compliance with wiring identification standards is essential.
Typical Applications
- Protective earth (PE) conductor identification.
- Industrial control panels.
- Electrical switchgear.
- Industrial machinery wiring.
- Cable harness manufacturing.
- Maintenance and repair work.
- Commercial and industrial electrical installations.
