OPGW Typical Designs of Central Stainless Steel Loose Tube
Details

3D.jpg


Fiber Type: G652D; G655C; 657A1; 50/125; 62.5/125; OM3; OM4 As Options

 

Applications:

●  Replacement of existing ground wires and reconstruction of old lines.

●  Applicable to low-grade lines, such as GJ50/70/90 and etc.

 

Main Features:

●  Small cable diameter, light weight, low additional load to the tower;

●  The steel tube locates at the center of the cable, no second mechanical fatigue damage.

●  Low resistance to side pressure, torsion and tensile (single layer).
