Fiber Optic Heat Resistance Tape Aluminum Tube OPGW Cable
Fiber Optic Heat Resistance Tape Aluminum Tube OPGW Cable
An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications.
Anoptical ground wire cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire.
Theoptical ground wire cable is run between the tops of high-voltage electricity pylons. The conductive part of the cable serves to bond adjacent towers to earth ground, and shields the high-voltage conductors from lightning strikes.
The optical fibers within the cable can be used for high-speed transmission of data, either for the electrical utility's own purposes of protection and control of the transmission line, for the utility's own voice and data communication, or may be leased or sold to third parties to serve as a high-speed fiber interconnection between cities.
1. Central Tube Optical Ground Wire (OPGW)
The Central Tube optical fiber ground wire (OPGW) 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
High quality standards for designing, testing and producing with grade A materials available to ensure long-term reliability.
Engineering support supervising and providing its own line of accessories hardware.
Seal stainless steel tube superior protection to the fiber optical to moisture and extreme environmental conditions such as lighting
To construct OPGW must cut power,resulting in greater loss,thus OPGW must be used in constructing high pressure line over 110kv
Apply to the transformation of old lines.
Central (Al-covered) Stainless Steel Tube OPGW
High quality standards for designing, testing and producing with grade A materials available to ensure long-term reliability.
Engineering support supervising and providing its own line of accessories hardware.
Larger tensile strength and fault current capacity to reach a better balance of electrical and mechanical performance.
4.Aluminum Tube OPGW
