Featuring corrugated steel tape and aluminum tape, these armored and double sheathed cables are suitable for installation in harsh environments where mechanical impact on the cable is expected, e.g. direct burial applications
The 250μm fibers are positioned in a loose tube made of high modulus plastic and filled with a water-resistant compound. A steel wire, sometimes sheathed with polyethylene (PE), is located in the center of the core and acts as a metallic strength member, protecting the integrity of the cable. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied to the cable core and filled with compound to protect from water ingress. Then the cable core is covered in a thin PE sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
