Fiber optic cables and photovoltaic cables, although they both belong to one type of cable, differ considerably in their definition, their use, their structure and transmission support. Photovoltaic cables and fiber optic cables are not the same thing.
Definitions
Photovoltaic cable
PV cable is mainly used for internal connection of solar power plants and is a special cable designed for photovoltaic power generation systems. It is responsible for connecting the photovoltaic modules, inverters and other equipment for power transmission and system control. In general, solar energy is converted into electrical energy (direct current), which is then converted into alternating current by the inverter to power equipment that requires electrical energy. Failure to use special cables for solar applications will affect the lifespan of the entire system.
fiber optic cable
A fiber optic cable is a cable that uses optical signals as a medium for transmitting information. It is a communication line in which a number of optical fibers are formed into a core in a certain way, with an outer cover, or in some cases an outer sheath, for the transmission of optical signals. The fiber optic cable est chargé de connecter les émetteurs optiques, signal amplifiers convert electrical signals into optical signals for transmission and enhancement, and receivers convert optical signals into raw electrical signals to complete the transmission of information. It is mainly used in the field of optical communication, such as telecommunications and satellite transmission.
Transport
Optical fiber cable mainly transmits optical signals and completes the transmission of information through the mutual conversion of electrical and optical signals.
The photovoltaic cable, as for him, transmits various forms of electrical energy, by converting solar energy and other forms of electrical energy to supplement the electrical supply.
Structure
The structure of PV cables is relatively simple and is generally divided into three layers, namely the inner layer, the insulation layer and the outer layer. The inner layer of PV cables is made of pure copper or tinned copper conductors, which are mainly used to transmit electrical energy.
The conductor diameter of a PV cable is larger than that of an ordinary cable, and its current transmission capacity is also higher.
The insulating layer of PV cables is made of polyolefin, which protects and insulates the inner layer, which allows the cables to be used in harsh environmental conditions. The outer material of the PV cables is corrosion and UV resistant, which effectively protects cables from environmental and chemical erosion. Parallel, the outer layer of PV cables has good abrasion resistance, at high temperature and low temperature, which helps maintain stable performance in various environments.
La structure de base du câble à fibres optiques est généralement composée d’une âme (fiber optics), a reinforcing steel wire, of a mastic, a sheath and other elements, as well as a waterproof layer, a buffer layer, insulated metallic conductors and other components as required.
Technical background
Photovoltaic cable
The photovoltaic cable industry began to develop in the years 1980 following the oil crisis and the search for alternatives in terms of renewable energy. Due to environmental protection and various excellent properties, this type of cable has received considerable attention and research. With the constant advancement of technology, the efficiency and stability of photovoltaic cables continues to improve, and the cost continues to decrease, which makes photovoltaic cables widely used in solar energy systems.
fiber optic cable
With the advent of the information age and exponential growth in demand, people urgently need a means of long-distance transmission, at high speed, high bandwidth, à haute sécurité et à haute protection environnementale pour répondre à la demande de transmission d’informations at high speed, and fiber optic cables were born. Fiber optic cable communication technology is developing rapidly, optical fiber is widely used in access networks, metropolitan networks and basic networks, thus becoming the ideal means of transmission.
Benefits
Photovoltaic cable
Compared to ordinary cables, les câbles photovoltaïques sont résistants aux températures élevées et aux rayons ultraviolets ; photovoltaic cables are oil resistant, with acid and alkali ; les câbles photovoltaïques ont une résistance élevée à la compression et sont plus résistants au froid.
Photovoltaic cables have high current transmission capacity and long service life. The conductor diameter of photovoltaic cables is larger and their current transmission capacity is higher. Parallel, photovoltaic cable conductor materials are also specially treated to provide high resistance to corrosion and aging, which makes it possible to meet the needs of long-term outdoor operation of photovoltaic energy production systems while extending the lifespan of photovoltaic cables, which is generally not less than 25 ans.
Photovoltaic cables are flame-retardant and halogen-free, energy efficient and environmentally friendly. The insulating layer of photovoltaic cables has excellent flame retardant properties, which effectively prevents fires. The main materials of photovoltaic cables are recyclable and meet environmental protection requirements. Furthermore, PV cables consume virtually no energy during transmission.
PV cables have good compatibility compared to ordinary cables. Cable insulation and jacket can be stripped in one go, which ensures good compatibility with standard joints or connection systems.
fiber optic cable
The main function of fiber optic cables is to transmit optical signals, qui peuvent transporter de grandes quantités de données et d’informations. Les câbles à fibres optiques ont une vitesse de transmission élevée, a large transmission capacity, long distance and high quality. The fiber optic cable itself is small in size, light in weight, wide by bandwidth, weak from loss, strong by anti-jamming power, high on reliability and low on cost, it has many advantages over ordinary cables.
Utilisation
Photovoltaic cable
Photovoltaic cables are mainly used to transmit and distribute electrical energy. They are generally used to connect the components of a solar power plant, such as solar panels, inverters, connection boxes, etc. They are also used to distribute energy to the different loads of a photovoltaic plant to improve energy utilization and economic efficiency.
fiber optic cable
With the advent of the era of high-speed communication, fiber optic cables are widely used in many fields such as telecommunications, satellite transmission, the internet, radio and television broadcasting, data centers, video surveillance, transportation, audio and video transmission, medical care, smart manufacturing, etc. due to their many characteristics, thus becoming an indispensable and important element in the field of modern communication.
In summary, fiber optic cables are used in the field of optical communications, while photovoltaic cables are used in the field of internal connections of solar power plants.
