Power poles
Power poles are structures designed to support wires and equipment of power transmission lines (PTL) of various voltage classes. They ensure reliable transmission of electricity, withstanding mechanical loads and environmental influences.
Classification of Power Poles
- By purpose:
- Intermediate poles: used on straight sections of the PTL route to support wires.
- Anchor poles: installed at points where the route changes direction or in areas with increased loads.
- By design:
- Single-column poles: consist of one column, used for lines with lower loads.
- Multi-column poles: include two or more columns, used on lines with higher loads.
- By material:
- Steel poles: offer high strength and durability.
- Reinforced concrete poles: characterized by corrosion resistance and long service life.
Technical Characteristics of Power Poles
- Pole height: determined by the PTL voltage class and terrain.
- Nominal load: depends on the number and cross-section of wires, as well as the climatic conditions of the region.
- Corrosion protection: includes hot-dip galvanizing or application of protective coatings to extend service life.
Advantages of Modern Power Poles
- Versatility: suitable for use in various climatic zones and operating conditions.
- Durability: service life of poles reaches 50 years or more with proper maintenance.
- Cost-effectiveness: optimized designs reduce installation and maintenance costs.
