2-288core Self-supporting Loose Tube Fiber Optic Cable OPGW
OPGW or known as Optical Ground Wire is a type of cable or wire that is used in transmission lines construction. It is also known as optical fiber composite overhead ground wire. It can serve as a grounding wire, shielding wire, and at the same time a cable used for communication purposes.
OPGW contains a tubular structure with one or more optical fibers in it. It is then surrounded by layers of steel and aluminum wire. It can be compared like an ASCR, except that steel is the one covering the tube with fiber optics inside.
1. Central Tube Optical Ground Wire (OPGW)
The Central Tube optical power 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
Good anti-corrosion performance.
Material and structure are uniform,good resistance to vibration fatigue.
Short circuit current has small effect on the optical fiber transmission properties.
Good anti-lightening performance.
