manufacturer supply telecommunication optical fibre Overhead Ground wire OPGW

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.

The optical fiber itself is an insulator and is immune to power transmission line and lightning induction, external electrical noise and cross-talk. Typically OPGW cables contain single-mode optical fibers with low transmission loss, allowing long distance transmission at high speeds. The outer appearance of OPGW is similar to aluminium-conductor steel-reinforced cable (ACSR) usually used for shield wires.

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.
