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?

Important! What You Need To Know About The Role Of Shielding In Control Cables


A shielded control cable is generally used as the connection line of electrical instruments.
It is suitable for the connection line of electrical instruments with an AC-rated voltage of 450/750V and below and the transmission line of the automatic control system.
It has excellent properties such as oil resistance, water resistance, wear resistance, acid and alkali resistance, resistance to various corrosive gases, aging resistance, and non-combustibility.

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.

Three-core Cables, A Better Choice to Ensure Safety and the Success of Project

TCCT

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.
