Key features and functions

Support high-voltage conductors: Their primary function is to hold the bare, high-voltage conductors of overhead power lines.

Ensure proper clearance: They keep the conductors elevated at a safe height, ensuring adequate space between the lines and the ground for people, vehicles, and other objects.

Withstand mechanical stress:

Their sturdy, often lattice-like steel construction is designed to withstand the mechanical load of the conductors and the stress from factors like wind and weather.

Various designs:

Towers come in different types based on their function, such as suspension, tension, and terminal towers, and their design can be adapted for specific needs like river crossings or sharp direction changes.

Durability and protection:

They are often made of galvanized steel to prevent corrosion and are designed for a long lifespan.

Steel Grade

High strength low alloy structural steel:

Q420B which is equivalent with ASTM Gr60

High strength low alloy structural steels:

Q355B which is equivalent with ASTM Gr50 or S355JR

Carbon Structural Steel:

Q235B which is equivalent with ASTM A36 or S235JR

Types of steel transmission towers

Lattice towers:

These are the most common type for high-voltage lines, with a framework construction of steel angle sections bolted together.

Tube towers:

Constructed using welded steel tubes, these also provide excellent strength and durability.

Single pole structures:

While often made of concrete or wood, steel versions are also used, especially where right-of-way is limited.

H-frame towers:

A standard type that uses two poles connected by crossbars to support a single circuit.

Components of Transmission Tower

01.

The Cage Of The Tower

The area between the body and the peak is the cage of the transmission tower. The vertical section of the tower, which has a cross-sectional design, is the cage. The design can take the shape of a square or a triangle according to the height of the tower.

02.

Peak Of The Tower

The portion at the top of the tower, which is above the top cross arm is called the peak of the tower. For the supply of electricity from tower to homes, an earth shield wire is connected to the top of the peak of the tower.

03.

Cross Arm Of The Tower

The side arms of the tower on both sides hold the transmission conductor is called the cross arm of the tower. The dimension of the cross arm depends on the transmission voltage, angle, stress distribution, and configuration of the wires. The cross arm of the tower helps in connecting wires from one tower to another.

04.

Transmission Tower Body

The distance from the lowest cross arm of the tower to the ground is called the transmission tower body. It is necessary for towers, as it provides the height of the tower required for ground clearance.

Package and Shipment

Our poles & towers as normal cover by sea/road-worthy wooden packing material, anyway also can following by client required, each 40HQ or OT can loading how many pcs will calculation base on the client actually specification and date.

Before shipment, we have a final inspector manager to check the products on every detail and component to make sure it all meet the drawing.
