Product Description

24 core optical ground wire overhead power line (OPGW) in aerial high-voltage electricity pylons

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. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire. The OPGW 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.

Applications
1.aerial ground wires
2. Power line communication systems

Feature
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 lightening.
4. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110KV.
5. Apply to the transformation of old lines.

Layer stranding structure

1.Big diameter and more optical fiber.
2.Big tensile strength and short-circuit capacity,arrive the best balance of machanical and electrical properties.
3.One or more optical unit.
4.Best design of stranding,obtain secondary optical fiber extra length.
5.Strands piles can be two or three,the wire can be ACS wire and/or the combination of aluminium alloy wire and aluminium wire.

Central tube structure

1.Small diameter and light weight,small short-circuit capacity.
2.Optical unit forms appropriate primary optical fiber extra length.
3.Characteristics of tension resistance,torsion resistance and side pressure resistance are good enough.
4.Suitable for matching with GJ-35,GJ-50,GJ-70.

The Aluminum tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. 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-lightning performance.
