48 Core Self-Supporting Overhead Ground Wire OPGW Optical Fibre Cable



The fibers is placed loosely in a sealed and water resistant stainless steel tube filled with water blocking gel. Two or three stainless steel optical tubes are helically stranded in the inner layer of a multiple-layer strandard cable. The multiple loose tube type is designed mostly for very high fiber count requirement over 48 with the maximum fiber count reaching 144. The multiple loose tube type can meet the requirement of huge cross and large current capacity.



  • Cable diameter and weight approximate with another ground wire. Less additional load to tower, high tensile strength.
  • 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.
  • Optical fibers are protected by stainless steel tubes.
  • Excellent security, good bullet resist performance.
  • ACSW, AAW and SST stranded design provide wide range combination of electrical conductivity and mechanical tensile strength.


  • Stainless steel tubes filled with hydrophobic gel provide the protection and support of the optical fibres.
  • Accurate process control ensures good mechanical and temperature performances.
  • Larger diameter, larger fibre count.Stable structure and high reliability.
  • High tensile strength and large short time current capacity to reach optimum balance of mechanical and electrical properties. 


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.
