The cobra 8t is made of polypropylene monofilaments braided into a hollow cable with a diameter of 28 mm and has a tensile strength of 10.9 t. The 12-fold braiding of 3 yarns allows for an unproblematic insertion of expanding insert and shock-absorber. Also the manual preparation of the quick splice is very easy - without any tools. The initial tensile strength of the system is 10.0 t.
The cobra 8t cable has a ultimate ductile yield of 17 % and a service ductile yield between 3 - 10 %.
The polypropylene monofilaments are extremely resistant to environmental influences and therefore have an excellent durability - they lose 2 - 3 % of their tensile strength per year of service. That is why the cobra 8t system is extremely long-lived and can reliably protect a tree from damage for a period of 8 years.
