Key Performance Advantages
Exceptional Submersible Capability
The (N)TSCGECEWOEU is engineered for permanent immersion in fresh, salty, and brackish water at depths of up to 300 metres, with AD8 waterproof rating. This makes it ideal for pumps, dredgers, floating docks, and offshore applications.
Superior Mechanical Durability
The individual copper wire screen on each phase core acts as a protective earth conductor, while the rugged 5GM3 rubber sheath provides outstanding resistance to abrasion, impact, and tensile stress encountered in trailing and reeling operations.
Excellent Torsional Resistance
With ±25°/m torsion rating, the cable withstands the high torsional forces generated during reeling and unreeling cycles on drum systems, particularly critical for tunnel boring machines and mining equipment.
High Safety Standards
The integrated UEL monitoring conductor enables continuous electrical integrity monitoring – a critical safety feature for hazardous mining and tunnelling environments. The cable is flame retardant to IEC 60332-1-2, oil-resistant to EN 60811-404, ozone-resistant, and UV-resistant.
Halogen-Free Option
The MT BMH PLUS variant features FRNC (halogen-free) rubber sheathing, significantly reducing toxic gas and smoke emission during combustion – essential for underground tunnel and mine safety.
