Description
● Central Stainless Steel Loose Tube OPGW Cable:
OPGW Mainly used for power communication with accessories, relay protection,automatic transmission,installation together with high-voltage lines. The central stainless steel tube is surrounded by single or double layers of aluminum clad steel wires (ACS) or mix ACS wires and aluminum alloy wires, which are the most widely used cables ,their design is fully adapted to the most common electric line needs.
● Fiber Type:G652D; G655C; 657A1; 50/125; 62.5/125; OM3; OM4 As Options
● 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).
● Applications:
►Replacement of existing ground wires and reconstruction of old lines;
►Applicable to low-grade lines, such as GJ50/70/90 and etc.
