How electrical conduits with wires facilitate the installation of systems

Added: Tuesday, 2/10/2026


In today's pace of installation work, every minute counts. Electrical installation pipes with wires are revolutionizing the way we approach the installation of electrical systems, offering ready-made solutions that significantly speed up the construction process and guarantee high quality workmanship. At Onninen, as a market leader in installation, we see a growing interest in these modern products among professional installers.

Our long-term contact with installers shows that the traditional method of running wires - first installing pipes, and then painstakingly pulling wires - is often a time-consuming process fraught with potential problems. Ready-made solutions in the form of pipes already filled with wires meet the real needs of the industry, offering installers significant time savings and a guarantee of hassle-free installation.

Why installers choose ready-made pipes with wires

From our experience as a supplier of installation solutions, it appears that electrical installation pipes with wires are gaining popularity for very specific practical reasons. Installers appreciate primarily the significant reduction in working time and the elimination of typical problems associated with pulling wires.

In the traditional method, the installer must first install the pipes and then pull the wires through them - a process that can be very problematic with longer runs or complicated layouts. Ready-made sets eliminate this stage, offering a complete solution ready for installation right away.

Main benefits for installers

  • Time savings - elimination of the wire pulling stage
  • Installation certainty - no risk of wires getting stuck or damaged
  • High quality - factory quality control of the entire set
  • Professional appearance - even arrangement of wires in the pipe
  • Cost reduction - less working time means lower implementation costs

Key applications in installation practice

In our daily cooperation with installers, we observe that electrical installation pipes with wires are used in a wide range of installation projects. They are particularly appreciated in situations where traditional installation would be difficult or time-consuming.

Concealed installations

In concealed installations, ready-made pipes with wires offer unparalleled installation convenience. The installer can immediately lay complete sections in grooves, eliminating the need to pull wires through already installed pipes later. This is especially important in the case of long runs or complicated layouts with many bends.

Modular construction installations

In modern construction, where speed of execution is crucial, ready-made sets of pipes with wires are invaluable. They allow for the preparation of complete installation modules before delivery to the construction site, significantly speeding up the entire process.

Renovations and upgrades

In renovation work, where access to installation routes is limited, ready-made solutions enable quick replacement of entire sections of the installation without the need for painstakingly pulling new wires through old pipes.

Technical aspects of choosing the right solutions

As experts in the installation industry, at Onninen we always emphasize that the choice of appropriate electrical installation pipes with wires should be tailored to the specific requirements of the project. Not all solutions will work in every situation.

Selection of cross-section and number of wires

In our assortment, you will find ready-made sets tailored to the most common installation applications. We offer configurations from simple lighting circuits with 1.5 mm² wires to power socket circuits with 2.5 mm² wires and special circuits with larger cross-sections.

Practical installation tips

From the extensive experience of our specialists, it follows that the proper installation of electrical installation pipes with wires requires adherence to certain technical rules. Below we present the most important recommendations from our practice.

Preparing the installation route

Before starting the installation, it is crucial to carefully plan the route and check whether the prepared grooves or channels have the appropriate dimensions. A pipe with wires requires a bit more space than an empty pipe, so it is worth considering this at the design stage.

Laying techniques

Our experience shows that the best results are achieved by gently guiding the ready-made sets, avoiding sharp bends or stretching. Pipes with wires should be treated as Corrugated gray protective pipe (PESZEL) RKWG-P 11-16 non-flammable with 750N remote control ONNLINE /50m/ W2710 a complete unit, being particularly careful at connection points with boxes.

Mounting and securing

In concealed installations, ready-made pipes with wires are mounted according to the standards for electrical installations, maintaining appropriate distances between mounting points. In Onninen's assortment, you will find a complete range of brackets and mounting elements tailored to different types of substrates.

Frequently asked questions

1. What are the main advantages of electrical installation pipes with wires?

The main advantages are significant time savings in installation and the elimination of problems with pulling wires. Ready-made sets allow installers to complete projects faster, reduce the risk of damaging wires during installation, and guarantee a professional appearance of the final installation.

2. In which installations do ready-made pipes with wires work best?

They are ideal for concealed installations, modular construction, and renovation work. Particularly useful in situations with long runs, complicated layouts, or limited access to installation routes. They also perform excellently in projects where speed of execution is crucial.

3. How to choose the appropriate pipe diameter for the number of wires?

The pipe diameter must allow for the free placement of wires while maintaining 40% free space. In practice, this means that for 3 wires of 1.5 mm², a pipe Ø16 mm is sufficient, for 3 wires of 2.5 mm², a pipe Ø20 mm is needed, and for a larger number of wires, pipes Ø25 mm or larger.

4. Can wires from different circuits be combined in one pipe?

No, only wires belonging to one electrical circuit can be run in one pipe. This is a basic safety rule for electrical installations. Wires from different circuits require separate pipes or channels, ensuring clarity of the installation and safety for users.

5. What tools are needed to install ready-made pipes with wires?

The basic set includes a pipe cutting saw, mounting brackets, expansion plugs, and screws. Depending on the type of installation, additional accessories such as connectors, elbows, or conduits may be needed. In Onninen's offer, you will find tool sets tailored to different types of installations.

6. How long can sections of pipes be without junction boxes?

The maximum length of a straight section is 5-6 meters, and at bends, a maximum of 2 meters. These limitations arise from the need to ensure the possibility of replacing wires in the future. In practice, this means that junction or connection boxes should be provided every few meters.
