Description of mining photoelectric fiber composite cable

The mining photoelectric fiber composite cable uses 250μm optical fiber in the loose tube of high modulus material and fill waterproof compound into the loose tube.

We use a metal strength member (with a layer of PE) as the cable core.

The loose tubes (with filler strip) and wire are stranded around the strength member into a compact and tight cable core which is filled with the filling compound to protect it from water ingress.

Polyethylene layer should be extruded out of the metal strength member to form the loose tube.
