Applications These corrugate steel tape and aluminum tape armored and double sheath cables are suitable for installation in harsh environments where mechanical impact on the cable is to be expected,e.g.direct buried application.They are also suitable of installation in ducts where the rodent resistance is to be expected or the moisture resistance is expected. Features Up to 432 fibers The loose tube stranding technology make the fibles have good secondary excess length and allow the fibles free movement in the tube,which keeps the fiber stress-free while the cable is subjected to longifudinal stress. Corrugated steel tape armored and double PE sheath providing excellent crush resistance and rodent resistance. Metal strength member provides excellent strain perforance
