# What Is High Voltage (High Tension Line)?

Have you ever wondered, what is High Voltage? The answer is quite simple and is used extensively in the energy industry’s power generation, transmission, and distribution sectors. It is essential to break down the main uses and where high voltage systems can be found below.

Remember: High Voltage is usually measured in volts, and it’s important to note that the higher the Voltage, the more dangerous it is.

## What Do We Know About High Voltage?

Voltage refers to the electric potential difference between two points in a circuit. High Voltage is the potential difference between two circuits above 35 kV.

So, what potential difference do we call high Voltage?

In brief, High Voltage (HV) is an electric potential difference or voltage intermediate between two electric circuits. High-Voltage Direct Current (HVDC) voltage sources are usually above 1000 volts, but the concept of high-voltage sources also applies to lower voltages.

The term “high voltage” is not generally used to refer to transmission voltages above 35 kV, even though these voltages are higher than those conventionally called “high-voltage.”

## Why Do We Use High Voltage?

High Voltage is a way to transmit large amounts of electric energy from a generator to another electrical substation if it’s further away. It’s used in high voltage transmission lines and high voltage cables.

If we want to send the power generated by hydropower plants, gas power plants, nuclear power plants, or wind power plants directly to users, high-voltage transmission lines are needed. That’s why it is said, “high-voltage transmission lines are the arteries of the electric power grid.

## High Voltage Transmission Line

This High Voltage electric transmission line is mainly used for long-distance transmission and long-distance distribution; the length is generally 1-100 kilometers. High voltage electric transmission line in the long span conductor, leakage current is small.

It has little impact on the tower structure to ensure good stability of the voltage drop caused by wind. The extended space power supply system uses high voltage electrical wire with excellent performance.

High voltage electric power transmission lines are usually made of steel tower structures, steel towers structures, or steel towers structures; concrete buildings are not commonly used.
