Structure Design
Description
In the Depuu ASU cable, fibers are positioned in central the loose tubes which is made of high modulus plastic materials, with two strength member (FRP) into a compact and circular cable core. The cable is completed with a PE outer sheath.
Application
Aerial
Features
Small size, Low cost. Up to 24 fibers.
Uni-tube gel-filled construction for superior fiber protection.
Two parallel FRP wire and overall glass yarn to enhance tensile resistant. and protect cable from mechanical damage.
Designed for use with inexpensive attachment hardware.
Self-supported no messenger needed.
