Shielding channels

Shielding channels are a key element of modern electrical systems. They provide effective protection of cables against electromagnetic interference. At Onninen, we understand their importance perfectly. Our experts advise on the selection of appropriate solutions every day. Shielding channels are used in a variety of facilities. They can be found in offices, production halls or data centers. Their role is invaluable in places with high signal intensity.

We offer a wide range of screening channels from renowned manufacturers. In our assortment you will find products from brands such as Onnline or FXA. These are our own brands, guaranteeing the highest quality at an attractive price. Various sizes and types of channels are available. Popular models are 40x20 mm and 40x33 mm. The selection of the right size depends on the number and cross-section of the cables. Our consultants will be happy to help you choose the best one.

Types and applications of screening channels

Shielding channels come in several main variants. The most popular are:

Aluminum channels - lightweight and corrosion-resistant
Steel channels - durable and providing the best screening
Plastic channels - economical and easy to install

The choice of channel type depends on the specific installation and the requirements for the level of shielding. In high-noise environments, we recommend steel ducts. They provide the highest attenuation efficiency. Lighter options are best for offices and less demanding locations. Plastic ducts are a good choice for budget-conscious users.

We recently completed a project for a large logistics center. The client needed a solution that was resistant to mechanical damage. We used 40x33 mm steel screening channels. They not only provided effective protection for the cables, but also ensured the durability of the installation. This is an example of how selecting the right type of channel affects the efficiency of the entire system.

Criteria for selecting screening channels

When selecting shielding channels there are several key factors to consider:

Type and number of cables to be routed
The level of electromagnetic interference in the environment
Requirements for mechanical resistance
Environmental conditions (humidity, temperature, exposure to chemicals)
Aesthetic aspects and architectural requirements

The correct selection of screening channels is crucial to the reliability of the installation. At Onninen, we often come across questions about optimizing cable systems. Our specialists always recommend a comprehensive approach. We take into account not only current needs, but also the potential for future system expansion.

Our experience shows that it is worth investing in higher quality solutions. Seemingly more expensive screening channels often turn out to be more cost-effective in the long run. They provide better protection, are more durable and easier to maintain. This translates into lower operating costs and a lower risk of failure.

Installation and maintenance of screening channels

Correct installation of screening channels is crucial for their effectiveness. It is worth paying attention to several aspects:

The continuity of the shielding is essential for the effectiveness of the protection. It is necessary to ensure proper connections between channel segments. Special connectors are used for this purpose, ensuring electrical conductivity. It is also important to ground the channel system. Properly performed grounding significantly increases the effectiveness of screening.

In the case of office reorganization, the need to modify cable routes most often arises. Screening channels facilitate such changes. Their modular design allows for easy adaptation to the new layout of the rooms. However, it is worth remembering to adhere to the assembly principles with each modification.

The maintenance of screening channels is not complicated, but requires regularity. Periodic inspections are recommended, especially in difficult conditions. The condition of connections and possible mechanical damage should be checked. If necessary, gaps in the screening coating should be filled. Proper maintenance extends the life of the system and maintains its efficiency.

In our daily practice, we see how important a professional approach to installation is. We recently helped a client modernize the system in an older office building. The use of screening channels allowed for the organization of the chaotic installation. This significantly improved not only the aesthetics, but also the electrical safety of the facility.

Onninen recommends the use of complete shielding duct systems. They provide the best compatibility of components and ease of expansion. In our offer you will find all the necessary components. From the ducts themselves, through mounting accessories, to finishing elements. Comprehensive solutions guarantee the highest shielding effectiveness.
