Special Cables / Reeling Cables - Tratosflex

TRATOSFLEX ES3 (Extruded screen) – Reduced weight and dimension medium voltage power cables (N) TSCGEWOU and TRATOSGREEN ES3 (Reduced halogens and reduced toxicity) is a TRATOS designed and manufactured flexible reeling cable for operation on cable reels on all kinds of cranes for material handling. They have special characteristics and high resistance to pulling tensions, being especially recommended for end feed applications or medium/ low travelling speed centre feed cranes. TRATOSGREEN ES3 (Reduced halogens and reduced toxicity) cables are recommended for applications where enhanced fire performance (LSZH) is required.
These reeling cables are yet more members of the wide range of TRATOSFLEX crane cables for power and data transmission in applications where the cable moves in operation.
The unique cable design focuses on tightening the internal structure, granting the cable exceptional strength and flexibility in a cable with a reduced outer diameter; this design prevents twisting and breakage and lasts longer under constant severe operating conditions, thus providing a reliable electrical feed and communication link to the is connected to.

TRATOSFLEX ES3 also features a red polychloroprene outer sheath, Tratosflex ES3 OS, equivalent to 5GM5, also if required, a conductor more flexible than Cl. 5 DIN VDE EN 60228 VDE 0295 and anti torsion protection. TRATOSGREEN ES3-FO (Reduced halogens and reduced toxicity) features a Low Smoke Zero Halogen sheath having the same robust characteristics as the halogenate Tratosflex ES3 OS sheath. These successful designs proven in Ports around the world allow these crane cables to outperform rivals on cranes in various ports around the world.

Today TRATOSFLEX cables are installed in more than 300 ports & terminals worldwide in the most demanding applications for prestigious global operators, including manual, semi-automatic and fully automatic yards. Its unique construction and materials make this cable suitable for end-feed applications and/or slower centre-fed machinery. This cable is recommended for various types of moving equipment inside ports, mining, shipyards and other industrial sectors; it can be found providing power to STS container cranes, Ship Unloaders (SU), Stacker Reclaimer (SR), Multipurpose Cranes or different kind of shipyard Cranes, these are just a few of the types of cranes where this crane cable is used.
