Supply and provide optical fiber overhead ground wire opgw to overhead power transmission lines
Overhead Stainless Steel Tube Optical Fiber Composite Ground Wire OPGW Cable
Overhead Fibre Optic Cables shall be 24 core
OPGW (Optical Ground Wire). The opgw optical ground wire is proposed to be installed on the transmission line 400kV IBTPS -Meramandali of Orissa Power Transmission Corporation Ltd. (OPTCL). The design of cable shall account for the varying operating and environmental conditions that the cable shall experience while in service. The exact transmission line details shall be collected by the Contractor during survey.
Several different styles of OPGW are made. In one type, between 8 and 48 glass optical fibers are placed in a plastic tube. The tube is inserted into a stainless steel, aluminum, or aluminum-coated steel tube, with some slack length of fiber allowed to prevent strain on the glass fibers. The buffer tubes are filled with grease to protect the fiber unit from water and to protect the steel tube from corrosion, the interstices of the cable are filled with grease. The tube is stranded into the cable with aluminum, aluminum alloy or steel strands, similar to an ACSR cable. The steel strands provide strength, and the aluminum strands provide electrical conductivity. For very large fiber counts, up to 144 fibers in one cable, multiple tubes are used.
1. Central Tube Optical Ground Wire (OPGW)
The
Central Tube opgw optical ground wire is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. are the most widely used cables, their esign is fully adapted to the most common electric line needs.

3.Characteristics:
Stranded Stainless Steel Tube OPGW
- 1.High quality standards for designing, testing and producing with grade A materials available to ensure long-term reliability.
- 2.Engineering support supervising and providing its own line of accessories hardware.
- 3.Seal stainless steel tube superior protection to the fiber optical to moisture and extreme environmental conditions such as lighting
- 4.To construct OPGW must cut power,resulting in greater loss,thus OPGW must be used in constructing high pressure line over 110kv
