MEDIUM VOLTAGE POWER CABLES (N)TSCGEWÖU+LWL VDE 0250 p.813 (as applicable) & HD 620 S1 p.9

Special Cables / Reeling Cables

TRATOSFLEX ES3-FO (Extruded screen) – Reduced weight and dimension medium voltage power cables (N) TSCGEWOU+LWL and TRATOSGREEN ES3-FO (Reduced halogens and reduced toxicity) according to standard VDE 0250 p.813 (as applicable) & HD 620 S2 and DIN VDE 0298-4 for current carrying capacity for continuous operation (at 30ºC): 3 cores + earth conductor; is a TRATOS designed and manufactured flexible cable for cable reels on all kinds of cranes for material handling, with special characteristics and high resistance to pulling tensions specially recommended for end feed applications or medium/ low travelling speed cranes. Another member of the TRATOSFLEX range of cables for powering and data transmission for moving applications. Its unique cable design focuses on tightening the internal structure, granting the cable phenomenal strength and flexibility and reduced outer diameter and weight, which prevents twisting and breakage and lasts longer under constant severe conditions for electrical feeding and communication for its correspondent equipment. TRATOSFLEX ES3-FO also features outer sheath red colour polychroprene Tratosflex ES3 OS, equivalent to 5GM5 if required, a conductor more flexible than Cl. 5 DIN VDE EN 60228 VDE 0295, Optical Fibre cable (9/125 Monomode or 62,5/125 multimode) and anti torsional protection. This successful design allows these cable to outperform rivals on cranes on various ports around the world. Today TRATOSFLEX cables are installed at more than 300 ports & terminals worldwide at 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 port machinery, mining, shipyards and other industrial sectors, and can be found for feeding purposes from STS container cranes, Ship Unloaders (SU), Stacker Reclaimer (SR), Multipurpose Cranes or different kind of shipyard Cranes, just to mention a few.
