TST

TST stands for Triple Stranded Tube and is especially designed for vertical installation purposes in harsh environments. This cable comes up with a design, where the three inner tubes are stranded along with a smooth pitch, allowing the fibers to hold their place while gravity wants to elongate or break them during hanging applications. A final protective layer made of a highly anti-corrosive steel grade allows using this product even in aggressive environments. Due to high-precision in the manufacturing processes, this cable design can be combined with additional layers of stranding wires or compact metal sheets for even more tensile strength or hydrostatic pressure ratings.
