Optical Power Ground Wire (OPGW Cable)
ZMS cable manufacturer’s aerial OPGW optical fiber cable is to place the optical fiber in the ground wire of the overhead high-voltage transmission line to form the optical fiber communication network on the transmission line. This structure has the dual functions of ground wire and communication. The optical power ground wire is more reliable, stable, and firm due to the metal wire wrapping. Because the overhead ground wire and the optical cable are combined as a whole, compared with other methods of optical cables, the construction period is shortened, and the construction cost is saved.
ZMS OPGW Optical Cable Manufacturer Characteristics & Advantage
Optical Power Ground Wire for Transmission Applications
Aluminum Tube Layer Warping Core Type OPGW
Our optical fiber is located in a PBT plastic loose tube, and the outside is covered with a seamless aluminum tube. The aluminum tube is stranded with 1 to 2 layers of monofilament, which can be all-aluminum-clad steel wire or a mixed twist of aluminum-clad steel wire and aluminum alloy wire.
Aluminum Tube Center Tube Type OPGW
This optical fiber product is located in a single PBT plastic loose tube, and the outside is covered with a seamless aluminum tube. The aluminum tube is stranded with 1 to 2 layers of monofilament, which can be all-aluminum-clad steel wire or a mixed twist of aluminum-clad steel wire and aluminum alloy wire.
Aluminum Clad Steel Tube Structure OPGW
The optical fiber is placed in a sealed stainless-steel tube, and the outer layer is covered with an aluminum layer to form an optical fiber unit. The aluminum-clad stainless-steel pipe is stranded with 1 to 2 layers of monofilament, which can be all-aluminum-clad steel wire or a mixed-stranded aluminum-clad steel wire and aluminum alloy wire.
Rust Steel Tube Structure OPGW - Layer Stranded
The stainless-steel tube is twisted with 2 to 3 layers of aluminum-clad steel wire, or the aluminum-clad steel wire and aluminum alloy wire are twisted together, which can accommodate single or multiple optical units.
Stainless Steel Tube Structure OPGW - Center Type
The center stainless-steel tube is twisted with 1 to 2 layers of monofilament, which can be all-aluminum-clad steel wire or a mixed-stranded aluminum-clad steel wire and aluminum alloy wire.
OPGW Optical Cable Application
OPGW aerial optical cable can adopt aluminum tube type, aluminum frame type, and (stainless) steel tube type structure respectively according to user needs. The optical fiber is sheathed in a tube made of stainless steel, the tube is surrounded by aluminum-clad steel wire (AS wire), and the outer layer is wrapped with aluminum alloy wire (AA wire) and twisted into a cable. We customize 2, 4, 6, 12, 24, 48 cores of OPGW optical fiber cable. Meanwhile, the price of our OPGW fiber optic cable is competitive.
- OPGW optical cables are mainly used on 110KV, 220KV, 550KV voltage level lines, and are mostly used in newly-built lines due to factors such as line power outages and safety.
- Lines with high voltage exceeding 110kv have a larger range (generally above 250M).
- Easy to maintain, easy to solve the problem of line crossing, and its mechanical characteristics can meet the line of large crossing;
- The outer layer of OPGW is metal armor, which does not affect high voltage electric corrosion and degradation.
- OPGW must be powered off during construction, and the power loss is relatively large, so OPGW should be used in newly built high-voltage lines above 110kv.
OPGW Optical Cable Related Accessories
Overhead Line Damper
The iron or aluminum metal accessories widely used in optical cable products are collectively referred to as fittings. There are many types of fittings with different uses. Most of the fittings need to withstand greater tension during operation, and some must also ensure good electrical contact at the same time. It is related to the safety of the wire or the tower. Even if one is damaged, it may cause a line failure. Therefore, the quality, correct use, and installation of fittings have a certain impact on the safe power transmission of the line.
