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).
