Outdoor cable available semi conductive buffer waterstop, semi conductive buffer resistance hose can also from between the two layers of non-woven fabrics with water blocking powder.

Once outdoor optical cable inlet, semi conductive buffer resistance hose inside the water resisting powder absorbent rapid expansion is dozens of times, produce the jelly like gel block water to cable deeper spread. The waterstop coated corrugated steel strip, strip the main role in the cable is resist compression, tensile, anti mouse bite, protect the beam pipe. Outside the steel strip, we see two parallel steel wire, the wire is the role of strengthening the tension of the cable.

Although the outdoor cable available semi conductive buffer resistance hose, but there are also some cable to a few beam tube stranded in a nonmetallic reinforcing core, stranded gap filling cable paste or insurance on a circle of semi conductive buffer resistance hose outside without armor directly extrude the sheath.
