Cables are an essential part of modern infrastructure. They play a crucial role in energy transmission, communications and control systems. With the development of electrical and communication networks on a global scale, Various cable technologies continue to emerge.
Whether for urban electricity networks, data centers or electric vehicle charging systems, the choice of cables directly influences the efficiency and safety of the systems.
In this article, we will take an in-depth look at several popular cable models in the international market, as well as their areas of application. The objective is to help industry professionals and buyers better understand the advantages of these cables and the selection criteria to consider.
Electrical cables
XLPE cables
Models : 1X120mm², 1X240mm²
XLPE cables (cross-linked polyethylene) are widely used in power transmission systems. They offer excellent thermal stability and electrical insulation properties. Thanks to these characteristics, XLPE cables have become the preferred choice for medium and high voltage electrical systems. What's more, they are resistant to high temperatures and corrosion, while having great mechanical robustness. Currently, 1X120mm² and 1X240mm² specifications are the most popular in the international market, finding their place in urban electricity networks and in industry. High electrical performance XLPE cables guarantees long-term security and stability.
PVC cables
Models : H07V-U, H07V-R
PVC cables are renowned for their economy and versatility. They represent an ideal choice for low voltage power transmission. H07V-U and H07V-R models are the most common for electrical wiring in buildings. They are popular due to their affordable cost and ease of installation, especially in interior constructions and commercial environments. Although PVC cables are not as high temperature resistant as XLPE cables, their economic advantage gives them a competitive position in low voltage applications.
Armored cables
Models : AWA cables (aluminum armored cables) an SWA (armored steel cables)
Armored cables have an additional layer of metallic protection, providing effective resistance to mechanical damage. AWA and SWA cables are the most common choices in environments likely to be disrupted by external factors. AWA cables typically use aluminum shielding, which makes them light, suitable for lightweight and construction systems. On the other hand, SWA cables are steel armored, providing enhanced mechanical protection. They are widely used for high intensity power transmission, especially in underground installations.
Fiber optic cables
Single-mode fiber
Models : G.652.D, G.657.A1
Single-mode fiber offers significant advantages for long-distance communications. The G.652.D and G.657.A1 models are the most common. G.652.D fiber displays low attenuation, ideal for data transfer over long distances. It is commonly used in the backbone networks of telecommunications operators and in fiber optic projects to the home (FTTH). For fibers G.657.A1, as for her, stands out for its flexibility and curvature performance, making it particularly suitable for installation in buildings. It is widely used in data centers and urban networks.
Fibre multimode
Models : OM3, OM4
Multimode fiber is typically used for short-haul, high-bandwidth applications, especially in data centers and local networks. OM3 and OM4 fibers are recognized for their wide bandwidth and rapid transmission capacity, supporting 10G speeds, 40G, even 100G. OM4 fiber, compared to the OM3, provides greater range and bandwidth capacity, giving it enormous potential for high-speed, data-intensive Internet applications.
High capacity fiber
Models : G.655, G.659
Faced with the rapid increase in demand for data transmission, high-capacity fibers become essential for long-distance telecommunications and wide-area networks. G.655 and G.659 fibers have excellent dispersion management, allowing high transmission speeds to be maintained over long distances. They thus meet the growing bandwidth needs of modern telecommunications networks..
Aerial fiber optic cable
OPGW
OPGW cables are composite aerial cables that combine the functions of optical fiber communication and power transmission. They are mainly used for high voltage transmission lines. OPGW cables are installed on electricity pylons, thus allowing them to benefit from their electrical and communication functions, and they are widely used by electricity companies.
ADSS
ADSS cables are self-supporting optical cables, capable of supporting their own weight and wind load without additional support structure. They are suitable for aerial installation in urban and rural areas, particularly for the communication needs of power lines.
Cables for electric vehicle charging systems
Connection cables for charging stations
Models : Type 1, Type 2, CCS charging cable
With the rise in popularity of electric vehicles, demand for connection cables for charging stations has exploded. Cables Type 1 and Type 2 are the main interface models between Electric vehicles and charging stations, while the CCS cable supports high-power fast charging. These cables are generally designed to be robust and resistant to wear, making them suitable for frequent use.
Power cables
Models : MV-90, EPR
Electric vehicle charging systems depend not only on connection cables, but also high voltage power cables to provide sufficient energy. MV-90 and EPR cables stand out for their excellent conductivity and durability, meeting the energy needs of charging stations.
Control and communication cables
Models : Low voltage control cables, CAN bus cables
Signal transmission is crucial when charging electric vehicles. Low voltage control cables and CAN bus cables are used in charging station control systems, ensuring the accuracy and stability of signal and data transmission.
Special cables
Fire resistant cables
Models : Nym, Nyy, Ny-j (Germany), FP200 (United Kingdom), Firetuf (multinational)
Fire-resistant cables are designed to maintain power transmission in the event of a fire, thus ensuring the proper functioning of emergency lighting and fire safety systems in buildings. German NYM cables, NYY et NYY-J, the British FP200 cable, as well as Firetuf brand models, are widely used in public spaces and industrial facilities.
Ecological cables
Model : LSZH cables (low smoke and halogen free)
LSZH cables do not release no toxic gases in case of fire, making it an example of an environmentally friendly cable. These cables are particularly suitable for high traffic locations, such as hospitals, shopping centers and schools.
Conclusion
The international cable market is constantly evolving, with extensive use of different models depending on their technical characteristics and areas of application. Whether for medium and high voltage power transmission with XLPE cables, or for fiber optic communication networks with single-mode and multi-mode fibers, all these types of cables contribute to the modernization of global infrastructure. In the future, with the generalization of charging systems for electric vehicles and the increase in ecological requirements, cable technology will continue to innovate to meet emerging needs.
