Why Can’t High-Voltage Cables Be Buried Underground?
What Is A High-Voltage Cable?
Ultra-high voltage transmission refers to the use of 500 kV-1000 kV voltage levels to transmit electricity.
If the 220 kV transmission index is 100%, the relative investment per kilometer of UHV transmission, the relative cost per kilowatt-hour electricity transmission a hundred kilometers and the consumption of metal materials, etc., have been significantly reduced, and the line corridor utilization rate has been significantly improved.
In our daily lives, we can often see the overhead ultra-high voltage transmission project, whether we have thought about the question: why can not be like the city underground cable, high-voltage power lines all buried underground?

6 Characteristics of Braided Cable
Braided cables are required for stability.
Crossed threads allow the braid to flex and stretch without bending, folding or kinking.
There are excellent electrical conductors braided cables and an electrostatic shield to ensure signal integrity.
Copper, tinned copper, and aluminum are examples of these conductors.
What Factors Affect The Output Power Of Solar Photovoltaic Modules
Solar modules are the core part of solar power systems.
Its function is to convert solar energy into electrical energy and send it to the battery for storage to facilitate the work of the load.
As an important part of photovoltaic modules, the output power of solar cables is very important.

Three-core Cables, A Better Choice to Ensure Safety and the Success of Project
Three-core cable helps connect devices and machines to the mains.
The size of the 3-core cables you choose to use and the way you design your circuit can also affect your project.
Because of differences in applications and variations in project specifications.
Additionally, high-voltage applications often require high-quality cables, known as steel wire armor (SWA), and their applicable standards and specifications.
Therefore, you must be familiar with the 3-core armored cable colors, and what the conductors of each color are for.
In this post, we will discuss all of these issues in more detail.
