The overhead OPGW fiber optic cable of ZMS fiber optic cable manufacturer is placed in the ground of overhead high voltage transmission lines to form a fiber optic communication network on the transmission line.
This structure has the dual function of ground line and communication.
The wrapping of the metal wire makes the fiber optic ground wire more reliable, stable, and solid.
As the overhead ground wire and fiber optic cable are combined into a whole, it shortens the construction cycle and saves the construction cost compared with other ways of fiber optic cable.
ZMS OPGW fiber optic cable manufacturer features and advantages
Adopting good stainless steel tube production technology, the tube is filled with a water-blocking compound, which can effectively protect the optical fiber.
Good compactness and high tensile strength.
Low mutual interference of short-circuit current to the power grid and communication network.
Similar specifications to common grounding wire, very convenient to erect, and can directly replace the original grounding wire.
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.
Good corrosion resistance
The material structure is uniform, and the vibration fatigue resistance is good
Short-circuit current has little effect on optical fiber transmission performance
The non-metallic tube is placed in the aluminum tube. And it is separated from the metal monofilament when it enters the connector box. The end of the optical cable is easier to handle, especially the optical fiber splicing
The internal non-metallic tube reduces the risk of damage to the fiber connection when the edge of the metal tube moves compared to the edge of the metal tube
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.
Good corrosion resistance
The material structure is uniform, and the vibration fatigue resistance is good
Short-circuit current has little effect on optical fiber transmission performance
The non-metallic tube is placed in the aluminum tube. And it is separated from the metal monofilament when it enters the connector box. The end of the optical cable is easier to handle, especially the optical fiber splicing.
The cable core is smaller than the aluminum tube type stranded cable core type OPGW, and the aluminum tube OPGW with a smaller structure can be made.
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.
The design of the aluminum-clad stainless-steel tube increases the aluminum cross-section, which can obtain better short-circuit current and lightning resistance characteristics.
Good corrosion resistance, suitable for areas with high corrosion environment, no need to use anti-corrosion cable paste separately.
Applied to lines requiring small cable diameter and large short-circuit current capacity.
This design can better enable the internal optical fiber to withstand lateral pressure and mechanical protection from the external environment.
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.
The cable diameter is larger, and the capacity of the number of fiber cores increases.
The tensile strength and short-circuit current capacity are larger, and the mechanical performance and electrical performance are better balanced.
The number of light units can be 1 to 3.
Obtain a suitable secondary excess length through the best twisting design.
2 to 3 layers of outer monofilament, which can be all-aluminum-clad steel wire or mixed-stranded aluminum-clad steel wire and aluminum alloy wire.
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.
The cable diameter is small, the weight is light, and the short-circuit current capacity is small.
The tensile strength and short-circuit current capacity are larger, and the mechanical performance and electrical performance are better balanced.
Slightly poor tensile, torsion, and lateral pressure resistance.
It is suitable for the transformation of general old lines, and the optical fiber has good strain characteristics under high tension.
OPGW overhead fiber optic cable can adopt aluminum tube type, aluminum frame type, and stainless steel tube type structure respectively according to users' needs.
The optical fiber is sheathed in a tube made of stainless steel, and the tube is surrounded by aluminum-clad steel wire (AS wire) the outer layer is wrapped with aluminum alloy wire (AA wire) and wound into a cable.
We can customize 2, 4, 6, 12, 24, and 48 cores of OPGW fiber optic cable.
Meanwhile, the price of our OPGW fiber optic cable is competitive.
OPGW optical fiber cable is mainly used on lines of 110KV, 220KV, and 550KV voltage levels, and is mostly used on new lines due to line blackout and safety factors.
Voltage over 110kv lines, the range is large, generally above 250M.
Easy to maintain, and easy to solve the problem of line crossing, its mechanical characteristics can meet the large crossing of the line.
The outer layer of the OPGW cable in transmission line is metal armored, which does not affect the corrosion and degradation of high-voltage electricity.
OPGW must be disconnected during construction, and the power loss is relatively large, so OPGW should be used in the new high-voltage lines above 110kv.
The iron or aluminum metal fittings that are widely used in fiber optic cable products are collectively referred to as fittings.
There are many types of fittings that serve different purposes.
Most fittings need to be able to withstand high tensions during operation, and some must also ensure good electrical contact, as these factors relate to the safety of the wire or tower.
Even if only one is damaged, it may lead to line failure. Therefore, the quality, proper use, and installation of the fittings have an impact on the safe transmission of power on the line.
ZMS's main fiber optic cable products include ADSS fiber optic cable, OPGW fiber optic cable, OPPC power cable, and other fiber optic cable products.
Our power fiber optic cable products are widely used in wind farm projects and power grid projects in many places to ensure the normal and stable operation of power communication lines.
We also support customized cables according to customer's specific needs for cables.
Difference between OPGW and ADSS Cable
If wires need to be rewired or replaced due to aging, it is more appropriate to use OPGW fiber optic cable.
Unlike OPGW fiber optic cable, ADSS fiber optic cable is more suitable for installation on energized lines in distribution and transmission environments.
What are the two fiber types in OPGW?
We have two main fiber types:
Single-mode
Multimode
ZMS cable products are manufactured according to GB, IEC, BS, NFC, ASTM, DIN, and other international standards. Our technical team can customize cable products that meet your requirements according to your need.
ZMS cable packaging is provided in the form of wooden reels, corrugated boxes, and coils.
The cable ends are sealed with BOPP self-adhesive tape and a non-hygroscopic sealing cap to protect the cable ends from moisture.
We can print the required marks on the outside of the barrel with waterproof material according to customer requirements.
