InArmor CST DJ
Corrugated Steel Tape (CST) Double Jacket (DJ)
Overview
InArmor CST DJ is a cost-effective and proven reliable design. It is a multi-tube cable with corrugated steel tape as an anti-rodent armoring and double jacket. Inner jacketing improves reliability. Apart from an excellent rodent resistance, this cable is also UV-resistant, so it features multi-purpose outdoor installation: from direct buried to duct and aerial lashed.
Typically, this cable consists of a stranded core with a central strength member (FRP) and dry loose tubes with optical fibers. The stranded core is fixed by water-swellable yarns. A water-swellable tape is laid over loose tubes. An armor of corrugated steel tape is laid over an inner jacket.
InArmor CST DJ’s maximum rated design tension can reach up to 607 lb but it may be produced with even higher MRDT up to 1.124 lb. It has a wide range of operating temperatures from -40°F to +158°F and installation temperatures from -22°F to +158°F (operating temperature range can be increased on request).
