OPGW Optical Cable is primarily used by the electric utility industry, placed in the secure topmost position of the transmission line where it “shields” the all-important conductors from lightning while providing a telecommunications path for internal as well as third party communications. Optical Ground Wire is a dual functioning cable, meaning it serves two purposes. It is designed to replace traditional static / shield / earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes.

Stranded stainless steel tube OPGW, Central Al-covered stainless steel tube OPGW, Aluminum PBT Loose Tube OPGW are three typical designs of OPGW optical cables.

The Stranded Optical Ground Wire (OPGW)

Structure: Double or three layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.

Application: Aerial , Overhead , Outdoor

Typical design for Double Layer:

Specification Fiber Count Diameter(mm) Weight (kg/km) RTS(KN) Short Circuit (KA2s)
OPGW-89[55.4;62.9] 24 12.6 381 55.4 62.9
OPGW-110[90.0;86.9] 24 14 600 90 86.9
OPGW-104[64.6;85.6] 28 13.6 441 64.6 85.6
OPGW-127[79.0;129.5] 36 15 537 79 129.5
OPGW-137[85.0;148.5] 36 15.6 575 85 148.5
OPGW-145[98.6;162.3] 48 16 719 98.6 162.3

Typical design for Three Layer:

Specification Fiber Count Diameter(mm) Weight (kg/km) RTS(KN) Short Circuit (KA2s)
OPGW-232[343.0;191.4] 28 20.15 1696 343 191.4
OPGW-254[116.5;554.6] 36 21 889 116.5 554.6
OPGW-347[366.9;687.7] 48 24.7 2157 366.9 687.7
OPGW-282[358.7;372.1] 96 22.5 1938 358.7 372.1

Central AL-covered Stainless Steel Tube OPGW

Structure: central AL-covered steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.AL-covered Stainless Steel Tube design increases the cross section of aluminum.

Application: Aerial , Overhead , Outdoor.

Typical Design for Single Layer

Specification Fiber Count Diameter(mm) Weight (kg/km) RTS(KN) Short Circuit(KA2s)
OPGW-80(82.3;46.8) 24 11.9 504 82.3 46.8
OPGW-70(54.0;8.4) 24 11 432 70.1 33.9
OPGW-80(84.6;46.7) 48 12.1 514 84.6 46.7

 

Typical Design for Double Layer

Specification Fiber Count Diameter(mm) Weight (kg/km) RTS(KN) Short Circuit(KA2s)
OPGW-143(87.9;176.9) 36 15.9 617 87.9 176.9

Aluminum PBT Loose Tube OPGW

Structure: single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.

Application: Aerial , Overhead , Outdoor

Technical Parameter:
Specification Fiber Count Diameter(mm) Weight (kg/km) RTS(KN) Short Circuit(KA2s)
OPGW-113(87.9;176.9) 48 14.8 600 70.1 33.9
OPGW-70(81;41) 24 12 500 81 41
OPGW-66 (79;36) 36 11.8 484 79 36
OPGW-77 (72;36) 36 12.7 503 72 67
