Optical Fiber Composite Ground Wire 52 Core Single Mode Multiple Loose Tube Type Overhead Aerial Opgw Cable
Description:
The Aluminum tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. Good anti-corrosion performance. Material and structure are uniform, good resistance to vibration fatigue, Short circuit current has small effect on the optical fiber transmission properties,Good anti-lightning performance.
Application:
Optical fiber composite ground wire [OPGW] is suitable for installation on new power lines with double function of ground wire and communication. Especially for installation on normal voitage and extra high voltage power lines. OPGW can replace conventional ground wire of old power line with increasing fiber communication function. They conduct short circuit current and provide lightning resistance.
Features:
1. Up to 144 fibers
2. Cable diameter and weight approximate with another ground wire. Less additional load to tower, high tensile strength.
3. Excellent stainless steel tube stranding technology make the fibers have good secondary excess length and allow the fibers free movement in the tube. Which keeps the fiber stress-free while the cable is subjected to longitudinal stress.
4. Optical fibers are protected by stainless steel tubes.
5. Excellent security, good bullet resist performance.
6. ACSW, AAW and SST stranded design provide wide range combination of electrical conductivity and mechanical tensile strength.
