High voltage cable is the main means of transporting electricity in the network. In cities, The power supply system plays an important role. In the choice of cable installation methods, The high voltage cable are not buried, which has advantages in terms of cable protection, heat dissipation and others.
For high voltage cable, The buried pose presents a series of inevitable problems. For example, The impact on the underground environment, The difficulty of construction, Maintenance work, the efficiency of transmission and other aspects.
Introduction of Cease at Hcar Tension
Before proceeding with aerial pose of high -voltage cables, It is essential to fully understand the structure and characteristics of high voltage cable operating.
As a type of electric line used to transmit a large current and high voltage, The high -voltage cable play a crucial role in connecting energy transmission links over long distances, such as power plants, Urban stations and power lines.
Limited by insulation materials, high voltage cables are generally Naked drivers without insulation.
The high -voltage cable structure is generally made up of naked conductors, which is limited by insulation materials. Unlike other power lines, High voltage cables generally do not have an insulating layer. This construction is designed to meet the specific operating requirements and the environmental conditions of high -voltage cable.
The naked driver design makes it possible to effectively reduce resistance and improve current transmission capacity, thus guaranteeing the stability and reliability of energy in the long -distance transmission process.
Characteristics of Cease at Hcar Tension
High -voltage air cables, As an electric lines carrying significant currents and high voltages, are generally subject to considerable voltage and current loads. Their tension levels can range from several thousand volts to tens of thousands of volts.
These high load working conditions have a direct impact on the operating state of the cable. High voltage cable must withstand very high voltages and currents during their operation in order to guarantee the stability of electricity transport.
Excessive load causes cable overheating, an increase in electric losses and other problems. In the most serious cases, It can even cause damage and cable failure.
Cable Hcar Tension Enterré
The installation of underground cables raises a number of complex questions and requires taking into account a certain number of factors in order to make a reasonable decision.
To determine if the high -voltage cable are suitable for underground installation, It is necessary to examine in detail security, loss of power, Maintenance costs, construction difficulties and other factors, and make scientific and reasonable decisions.
L’IMPACT DE L’Envirt SOuterrain on the Cable
As part of long -term use, humidity, The temperature and salinity of the underground environment will also have an impact on the performance and safety of high -voltage underground cables.
Humidity can cause aging of the cable, temperature changes can affect cable conductivity, and salinity and alkalinity can speed up corrosion of the cable and therefore reduce its lifespan.
Therefore, The long -term stable exploitation of underground cables is faced with many uncertainties and many challenges.
Maintenance and Rwilness
When the underground cables are defective or damaged, their revision and repair often require a lot of time and labor. Ensuite, The difficulty of locating and repairing cable defects is also one of the difficulties in maintaining underground cables.
Furthermore, untimely maintenance and repair can also have an impact on the reliability and speed of the restoration of the power supply, which harms the normal functioning of the city.
Difficulties and Cwhere Construction
Underground construction requires significant human equipment and human resources. Construction high -voltage underground cables requires large excavators, installation machines and other specialized equipment, as well as a large workforce for collaboration, which increases the difficulty and cost of construction.
Secondly, The complexity of the land and the obstacles to construction also constitute challenges for the installation of underground cables. There are underground installations such as roads, des pipelines, metros, etc. in the city, And the presence of these installations increases the difficulty of building underground cables and increases the risk of failures and accidents.
Selection of Maerial ISolants
High voltage cables buried must be covered with appropriate insulating materials to guarantee safety and stability during electricity transport.
However, There is currently no material capable of effectively responding to UHV cable insulation requirements.
On the other hand, For very high voltage cables, There is currently no effective insulating material. The current will run away through the capacitor, resulting in a loss of power. What's more, These leaks lead to significant risks for the safety of staff and equipment.
Advantages of POR Aerian Cà lap Hcar Tension
According to the analysis of the cable operating conditions, The air voltage cable has major advantages in terms of maintenance, cost and insulation.
During the transmission of important currents, High voltage cable generates a lot of heat. The cable placed in aerial is exposed to air and has good conditions of heat dissipation. This promotes the reliability of energy transmission.
Air is a good insulation, which can effectively prevent direct contact of the current between the wires. This reduces the appearance of electrostatic damage and short-circuit defects.
The earth is electrically conductive, Thanks to high -voltage cable landing. The current can be channeled towards the earth, which avoids overload of the electrical system.
High voltage cable are placed at high altitude, which can reduce contact with ground objects and improve the safety of the electrical system.
In RESUMÉ
In summary, to guarantee safe and reliable cable operation, It is recommended to use the aerial installation method in order to avoid the various problems that can occur during the underground pose of high voltage cable.
