Description
● Stranded Stainless Steel Tube OPGW Cable:
OPGW Mainly used for power communication with accessories, relay protection,automatic transmission, installation together with high-voltage lines. The Stranded Optical Ground Wire (OPGW) is stranded by double or three layers of aluminum clad steel wires (ACS) or mix ACS wires and aluminum alloy wires, Its 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:
►Stable structure, high reliability;
►Able to obtain the second optical fiber excess-length;
►Excellent resistance to distortion and side pressure;
►Can withstand high mechanical stress, and excellent lighting protection performance.
● Applications:
►Commonly used in newly built overhead power lines;
►Can meet the requirements of big number of fibers and ultra high voltage (UHV) transmission lines;
►Can provide protection against lightning by transmitting large fault short-circuit current.
