Tension Towers

Tension towers are a type of transmission tower used to handle the pulling force and tension in overhead power lines where the line changes direction, terminates, or spans long distances. They are designed to bear significant longitudinal mechanical loads and provide stability, unlike the simpler suspension towers that mainly support the weight of the conductors between them. These towers use strain insulators to securely anchor the conductors and play a crucial role in isolating parts of the line for maintenance or protection.

Key functions

Handle direction changes:

They are used at points where the transmission line turns, such as angle towers, at the end of a line (terminal towers), or where lines split (branch towers).

Bear longitudinal forces:

They are built to withstand the pulling force of the conductors in the direction of the line, a stress much greater than what suspension towers experience.

Provide stability:

They serve as strong anchoring points that prevent the entire transmission line from becoming unstable and collapsing progressively.

Isolate sections:

By breaking the continuity of the mechanical load, they help isolate sections of the line for maintenance or to limit the impact of a fault.

Design and features

Insulators:

They use strain insulators, which are often arranged horizontally, in V-strings, or inverted V-strings to manage the increased mechanical stress.

Structure:

Their design can vary, with some common configurations including cup-shaped, cat-head shaped, and cantilever-shaped towers.

Placement:

To maintain stability, they are typically spaced no more than 15 spans or 5 kilometers apart.

Large Angle Tower with Tension Strings

Deviation angle:

45º–60º (69kV to 230kV) and 35º–60º (380kV)

Purpose:

Designed for high-stress deviation points.

Key Notes on Tower Design

Deviation Angles & Spans:

Angles mentioned are for the design ruling span, but can be optimized depending on clearances and safety factors.

Wind & Load Conditions:

Towers must meet strict clearance, phase spacing, and safety requirements under worst-case conditions.

Special Designs:

For sites requiring longer spans, custom towers are designed with optimized conductor spacing.
