一、 Definition and function of holding pole
Holding poles refer to metal components installed in power, communication, lighting and other lines to support and fix wires, cables, equipment, etc., also known as pillars in power line equipment. Its function is to bear the weight of the line, maintain the geometric shape of the line, isolate the air gap between the line and the supporting structure, and ensure that the distance between the wire insulator and the bracket meets the requirements, ensuring the safe operation of the line.
二、 Type and characteristics of pole
1. V-shaped pole
V-shaped pole, as the name suggests, has a V-shaped shape and is a common type of pole. Usually used for light power lines such as medium voltage power lines or communication lines, it can meet the requirements of line support, maintenance, and isolation. The V-shaped pole has the characteristics of light weight, beautiful appearance, convenient installation, and high reliability.
2. U-shaped holding pole
U-shaped pole, as the name suggests, is a type of pole that forms a U-shape. It has a wide range of applications and is mainly used for power transmission, transformation, distribution and other power lines. The installation of U-shaped pole has strong practicality, flexible installation methods, and can meet the installation needs of various power grid conditions. The U-shaped pole also has strong wind pressure resistance and good corrosion resistance.
3. Straight holding pole
A straight pole is a type of pole shaped pole commonly used in power and communication lines. It has the characteristics of easy installation, strong load-bearing capacity, and stable center of gravity. The straight pole is mainly used in high-voltage power lines and heavy-duty communication lines.
4. Irregular holding pole
Heterogeneous pole is an unconventional type of pole, which not only has the basic functions of traditional poles, but also meets the requirements of line rigidity, as well as aesthetic and anti theft functions. Heterogeneous poles are widely used in fields such as power, communication, and lighting.
三、 Application fields of holding poles
In addition to the basic power and communication fields introduced above, pole holders are also applied in urban lighting, bridge and tunnel lighting, environmental protection, river and ocean monitoring, and other special equipment fields. In different application fields, it is necessary to select different types of poles for installation to meet the actual needs of the project.
