Why Choose the Cembre 4297742 H2-32-25-WH2 Heat-Shrink Cable Marker?
The Cembre 4297742, manufacturer type H2-32-25-WH2, is a white TERMO-ROLL H2 heat-shrink cable marker designed for clear, durable identification of electrical cables, conductors, pipes and conduits. Manufactured from cross-linked polyolefin, the marker combines a compact format with excellent identification performance for professional electrical, industrial, rail and infrastructure applications.
Part of the Cembre TERMO-ROLL H2 series, the H2-32-25-WH2 uses a 2:1 shrink ratio and is supplied in pre-cut 25 mm lengths that can be printed on both sides. Its halogen-free, flame-retardant construction with low smoke emission makes the H2 range particularly suitable for applications with demanding safety requirements, including tunnels, underground installations, railway systems, marine environments and industrial equipment.
The H2-32-25-WH2 is designed for conductors with a cross-sectional area of 0.5–1 mm² and cable diameters of approximately 1.8–2.8 mm. The marker has a nominal pre-shrink diameter of 3.2 mm, a minimum shrink temperature of 90 °C and an operating temperature range of -40 to +105 °C.

Heat-shrink cable markers provide a permanent and space-efficient method of identifying individual conductors, cables, pipes and conduits. Once positioned and heated, the marker shrinks around the cable to provide a secure fit while retaining clearly printed identification for installation, commissioning and maintenance work.
The Cembre TERMO-ROLL H2 range is particularly suited to environments where fire performance and low smoke emissions are important. Its halogen-free, flame-retardant construction makes the range suitable for enclosed and safety-critical locations, while the printable white surface provides high-visibility identification for complex electrical installations.
Typical Applications
- Electrical cable and conductor identification.
- Control panels and industrial automation systems.
- Railway electrical and signalling installations.
- Tunnels and underground infrastructure.
- Marine electrical installations.
- Machine building and OEM equipment.
- Industrial wiring and maintenance applications.
