Multifaceted portals of ODD

Effective management of electrical networks ensures the uninterrupted operation of businesses, infrastructure, and residential sectors. Open distribution devices (ODDs) are key components of energy substations. They enable the reception, distribution, and transmission of high-voltage electricity. The efficiency and safety of ODDs impact the stability of power supply, which is why they require reliable supporting structures — metal portals.

Metal portals are the main load-bearing structures of ODDs. They withstand significant loads of switching equipment, busbars, and weather conditions. Their primary functions include connecting power lines, distributing electricity between multiple users, and managing electrical loads. The choice of material and design directly affects the stability of the entire energy infrastructure. Reliable metal constructions reduce the risks of emergency situations and ensure a long operational lifespan.

Metal ODD portals consist of separate metal elements forming a U-shaped structure. They feature vertical multifaceted supports connected by horizontal crossbars using flanges. This design ensures a secure connection both to the foundation and between the individual components. The number of spans depends on the substation's specific requirements, allowing for portals with one or several sections.

Multifaceted metal portals are made from high-quality steel. The manufacturing process includes bending steel sheets, welding, and applying anti-corrosion treatment. The design of multifaceted portals ensures an optimal balance between strength and lightness. They offer even load distribution, reducing the risk of deformation. Due to their modular design, they can be adapted to meet various technical requirements of substations.

Modern multifaceted metal portals offer several advantages over traditional lattice and reinforced concrete structures:

• STRENGTH AND RELIABILITY:
  Multifaceted structures have high load-bearing capacity. They maintain their operational characteristics even under extreme weather conditions and heavy mechanical loads.

• COMPACTNESS AND MINIMAL LAND ALLOCATION:
  One of the key benefits of multifaceted ODD portals is their ability to occupy minimal space when installed. Their design allows to install them in hard-to-reach areas, which is particularly useful for urban substations or sites with limited space.

• FAST INSTALLATION:
  The installation of multifaceted ODD portals takes minimal time and labor (compared to lattice structures), thanks to their simple design and fewer components. Unlike reinforced concrete counterparts, multifaceted portals are lighter, which reduces transportation and installation costs.

• EASE OF TRANSPORTATION:
  Multifaceted portals have a compact design and take up significantly less space during transportation compared to other types of structures, which lowers transport costs.

• REDUCED WIND LOAD:
  Their aerodynamic shape helps evenly distribute wind pressure, which is particularly important for open areas.

• SEISMIC RESISTANCE:
  Due to the optimal distribution of mass, multifaceted portals are better able to withstand seismic loads. They minimize the risk of damage during earthquakes.

• CORROSION PROTECTION:
  Multifaceted ODD portals are subjected to anti-corrosion treatment through hot-dip galvanizing, which coats both the outer and inner surfaces of the structure. This is especially crucial in regions with high humidity or aggressive environments. The anti-corrosion coating extends the portal’s service life to up to 70 years.

Multifaceted metal portals represent a modern, reliable, and efficient solution for open distribution devices. They outperform traditional lattice and reinforced concrete structures in many aspects. Choosing these portals helps minimize installation and maintenance costs.
