Core Features

1. Excellent resistance to lateral pressure and impact with high mechanical strength. It can withstand squeezing from earth and rocks as well as rock impacts, protecting the inner cable core and optical fibers from damage caused by external compression, making it suitable for direct burial installation.

2. Galvanized anti-corrosion protection. The hot-dip galvanized or electro-galvanized coating on the surface isolates air and moisture to slow down substrate corrosion. It can operate stably for a long time in ordinary soil and common underground pipeline environments.

3. Good bending and forming performance. Thin-gauge steel strips feature great flexibility and can be longitudinally wrapped. They are compatible with high-speed cable forming equipment for optical cables and closely fit the cable core after longitudinal wrapping.

4. Cost advantage. It is cheaper than stainless steel strips and serves as the most dominant armoring material for ordinary directly buried optical cables.
