**[Transmission towers](https://forumelectrical.com/stringing-in-electrical-transmission-lines/)** are an important part of the electrical power transmission network.

They support conductors and maintain the required mechanical strength and electrical clearances.

## 1). Suspension / Tangent Tower

Used mainly on straight sections of a transmission line.

## 2). Tension / Strain Tower

Designed to withstand conductor tension and used at section points and important crossings.

## 3). Angle Tower

Used where the transmission line changes its direction.

## 4). Dead-End / Terminal Tower

Used at the end of a line or near substation entry/exit points and designed for high conductor tension.

## 5). Transposition Tower

Used to change the physical position of the three-phase conductors to maintain better electrical balance.

## 6). Special Tower

Used for special requirements such as river, railway, highway or long-span crossings.

**Tower classification by circuits:**

**Typical Power Flow:**

The correct tower design depends on voltage level, line angle, span, conductor loading, terrain, wind conditions and crossing requirements.
