A Best & Reliable OPGW Cable Manufacturer since 2000

Here is some brief introduction & guide of an OPGW cable

With the rapid development of the power industry and the improvement of modern management level in the power system, the form and capacity of information that needs to be transmitted within the power system are increasing day by day. The advantages of an OPGW Cable include large transmission capacity, fast speed, suitability for long-distance transmission, resistance to electromagnetic induction and crosstalk interference, and the high mechanical performance, high conductivity, and good corrosion resistance of aluminum clad steel wire. . OPGW optical cable has double functions for both lightning protection and communication.  Therefore, OPGW optical cable is now widely used in overhead transmission line grounding. The use of OPGW optical cables as overhead ground wires has many advantages: ① low transmission signal loss, high communication quality, and the number of cores of the optical cable can be large; ② Good safety, less prone to theft and cutting, and less susceptible to destructive shooting; ③ Suitable for transmission lines with multiple voltage levels; ④ Fiber optic cables and conventional ground wires are integrated, avoiding the huge cost of duplicate construction and maintenance.

The exact type of OPGW Cable used in the project varies depending on the ice zone and the cross-section of the wire. In addition to meeting the cross-sectional requirements required by the regulations, it is also necessary to meet the requirements that when a line fault occurs, a large short-circuit current will pass through the ground wire, causing a sharp increase in temperature of the ground wire, which may cause damage to the ground wire. Therefore, the selected overhead ground wire should also meet the requirements of thermal stability.

What types of an OPGW Cable

There are a wide variety of OPGW cable with different fiber counts;

Central aluminum pipe OPGW Cable

Stainless steel tube OPGW Cable in a central or a stranding form with a single or double layer, which is preferred to use on some HV power transmission lines.

Aluminum cladding stainless steel tube OPGW cable in a single or double layer.

Components of an OPGW cable

1. Optical unit to house different fibers on custom request
2. Aluminum wire, aluminum cladding steel wire or aluminum alloy wires for a higher strength and corrosion resistance in some polluted areas or coastal areas.
